INTRODUCTIONAria is an electronic controller for the management
of direct expansion air-conditioning developed by Carel for the
home andcommercial markets.It features a room terminal which
communicates with a power board installed on the air-conditioning
unit itself.

With its accurately-designed appearance, it is ideal for the
sector it is used in. Another important feature of the product is
its easeof use, with a large LCD display and a highly intuitive
user interface.

Furthermore, unlike other existing products on the market, the
connection of the actuators is handled by an electronic
boardlocated directly on the machine’s electrical panel, thus
avoiding the need to lay large quantities of cables to the control
itself.

The serial communication allows cabling reduction between the
terminal and the power board to just 2 wires.The instrument can
manage both conventional units and heat pumps with up to a 3
heating and 2 cooling stages (in a single

refrigeration circuit); its operational flexibility is
guaranteed by a parameter used to quickly configure the type of
air-conditioning unit being controlled.

A special version is also available for multi-zone applications,
in which up to 30 terminals are located in different
rooms,measuring the local temperature and optionally humidity, then
communicating with the control of the centralised air-conditioning
unit (pCO or pCO2).

1. GENERAL CHARACTERISTICS

1.1 Functions

Aria is a Carel electronic microprocessor-based control designed
by Carel to manage single or multi zone Air Conditioning units
inresidential/commercial applications. Aria is organized into two
integrated systems: aterminal, installed in the room, and a
powerboardfor managing the actuators to be placed in the electrical
panel of the Air Conditioning unit itself. The terminal is
connected tothe power board using a two-lead cable, thus greatly
simplifying installation.The power board is available in two
different models, depending on the specific application:

one model for the control of stand alone air-conditioning units
(relay power board)

one model for the control of a motorized damper, where Aria is
used for zone control (triac power board).

1.2 Terminal

The terminal is the heart of the system; it is fitted with an
internal probe for measuring the ambient temperature (this may be
remotely-

located in the duct) and can be supplied with an extra
active-type probe (0/1Vdc output) for measuring the ambient
humidity.The instrument’s user interface has been designed for ease
of use, featuring:

the use of a complete and large-sized liquid crystal display

the ergonomic separation of the buttons for programming (on the
side) from those used for the immediate modification of thedesired
temperature (set point), placed on the front

the back-lighting of the buttons and the display, useful when
there is not enough light

a built-in buzzer (can be bypassed using a specific parameter)
which signals any operating anomalies of the unit, and alsofollow
the pressing of each button.

The presence of an optional real time clock allows the
instrument to be independently time-band programmed each of
theseven days of the week. Being fitted with an independent power
supply, it constantly maintains the correct time even in thecase of
interruption to the main power supply.

The terminal is very easy to install, as:

just 2 leads connect the terminal to the power board

the quick insertion terminals used allow the connection of the
cables to the terminal using the rear shell of the box;
theelectronic parts are connected at the end, as the front panel is
closed.

the instrument may be programmed by simply copying the settings
from another master machine, using a hardware key

Figs.: 1.2.1 and 1.2.2 represent respectively the rear view of
the terminal and the view of the rear shell.

1.4 Power board for the control of a motorized damper
(multi-zone system

codeTAZONE0000)

This board manages the motorized inlet air damper with a 3-point
control, typically in multi-zone applications.Its main features
are:

two 24Vac triac outputs to control damper opening/closing

three multifunctional digital inputs (see 5.6);

one analogue input, for automatic cooling / heating selection
using the probe located inthe air duct (see 5.2.8).

The following areas of connection can be identified on the
board:

G and G0 for power supply (24Vac)

terminals T-and T+for connection to the terminal

terminals ID COM, ID1, ID2 and ID3for connection of the digital
inputs

terminals B3and GNDfor connection of a NTC temperature probe

terminals OUT1, OUT2 and C to open and close the zone
damper.

2. APPLICATIONS

The Aria control can be used in a wide variety of applications,
which are selected using the parameter H1. The possibleapplications
can be divided into two families:

stand-alone applications, where Aria controls directly the
air-conditioning units via relay power board. The power boardis
available in two different models, with either 5 or 7 relays (part
no. TABASE5000 and TABASE7000).

multi-zone application control where a series of terminals are
connected to a Carel pCO programmable control using the CarelpLAN
local network (pCO Local Area Network). In this situation the
terminal ARIA measures the temperature and the humidity of

the zone, sends the data via pLAN to the centralized machine’s
controller pCO or pCO2, which, depending on the informationreceived
from the other zone terminals (up to a maximum of 30), decides the
operating logic and thus the temperature and humidityof the air to
be introduced into the duct. Each terminal is connected to triac
power board (code TAZONE0000) which manages the

local zone damper (with floating control) in order to maintain
the required ambient conditions.WARNING: before modifying parameter
H1and thus changing the type of application, the machine should be
switched OFF(by keypad), as the outputs will change their function
immediately after each change of H1.

2.1 Stand-alone applications

The list below describes the value of parameter H1 and the
function of each relay for each application, using the
followingabbreviations:

3. INSTALLATION

3.1 Terminal installation

For correct installation, the following warnings must be
heeded:

always disconnect the power supply before performing any
operations on the board during assembly, maintenance or
replacement.

the terminal must be mounted vertically, allowing for air to
circulate through the instrument’s vent-holes. Avoid placeswhere
the measurement of the ambient temperature by the internal sensor
may be altered, such as outside walls, near doors

leading outside, in direct sunlight, etc. the cables for
connection to the power board must be kept separate from other
cables, using an individual raceway and,

possibly, shielded cables. In such a case connect the cable
braid to terminal G0, reference for the 24Vac power supply
(leavethe other side of the braid free). The maximum length allowed
is 150m, according to the section of the cable, as per the
table:

length of connection (m) minimum cross-section (mm2)

0 — 50 0.5

50 — 150 1

Tab. 3.1.1

when making the connection to the power board special attention
must be paid to the polarity; the T+ pin on the terminal sidemust
be connected to the T+ pin on the power board; similarly for the T-
pin ( however in case the cables are connected inthe opposite order
the instrument will not be damaged).

The installation procedure is the following:1. To detach the
front panel of the terminal from the rear shell, place a flat-heat
screwdriver in the slot in the centre of the

bottom side of the housing and release the locking flap (Fig.
3.1.1).

2. Raise the front panel using a hinge movement, using the upper
edge of the instrument as the pivot and raising the loweredge (Fig.
3.1.1);

3. To mount the rear shell to the wall, place the hole in the
centre of the shell over the control cables of the instrument
whichcome out of the wall. The placement of the mounting holes has
been designed to allow the instrument to be fixed ontostandard
European flush mounting boxes conforming to standards CEI C.431 —
IEC 670. If this is not available, use themounting holes on the
shell as a guide for drilling holes into the wall and then use the
screw and plug kit supplied.

4. Connect the cables to the terminals on the rear shell of the
terminal, as indicated in Fig. 3.2.1 or Fig. 3.4.1, according to
theapplication you are facing to (stand alone or multi-zone).

5.

Check the correct installation of the two jumpers J1 and J2
located on the rear side of the terminal (see Fig. 1.2.1)6.
Finally, close the instrument, moving the front panel onto the rear
shell with a hinge movement, in the opposite way asused for
opening. First the long side of the front panel near the display is
snapped onto the rear shell, then the opposite side,being careful
that the terminal pins slide into their corresponding female
terminals.

3.3 Installation of the relay power board (STAND ALONE system)
and multi-zone

power board

The power board may be installed on the electric panel of the
air-conditioning unit to be controlled. Its dimensions, DINstandard
compatible, allow installation on omega rail by means of suitable
adapters available on the market. Connect the

actuators as in Fig. 3.2.1; the relays no.1 and no.2 have dual
contacts, while the others have only one contact, normally open.For
a description of the devices controlled by each relay please refer
to the Applications (pg. 7), according to the specificconfiguration
of the machine.

The digital inputs ID1, ID2, and ID3 are optically insulated and
suitable for 24Vac/dc signals with normally closed logic (atthe
contact opening there is alarm condition). To simplify the wiring
it is possible to get the 24Vac/dc power supply from theGND
terminal (see Fig. 3.3.1). In fact J3 jumper can be placed as
follows:

J3: in position1-2(INT — ID COM): digital inputs powered
internally (Fig. 3.3.1);in position 2-3(ID COM — EXT): 24Vac/dc
power supply to be provided by the user (Fig. 3.3.2).

In order to get a real optical insulation, digital inputs power
supply must be different from the one on the board that is
24Vac/Vdc. In case the digital inputs are supplied by direct
current, the IDCOM terminal must be connected to the positive
pole,ID1, ID2 and ID3 to the negative one.

For correct installation the following warnings must be
heeded:

always disconnect the power supply before performing any
operations on the board during assembly, maintenance or
replacement.

the cables for connection to the power board must be kept
separate from other cables, using an individual raceway
and,possibly, shielded cables. In such a case connect the cable
braid to terminal G0, reference for the 24Vac power supply
(leavethe other side of the braid free). The maximum length allowed
is 150m, according to the section of the cable, as per table
3.1.1.

when making the connection to the power board special attention
must be paid to the polarity; the T+ pin on the terminal sidemust
be connected to the T+ pin on the power board; similarly for the T-
pin ( however in case the cables are connected in

the opposite order the instrument will not be damaged).

For the multi-zone power board (TAZONE0000), follow the same
correct installation procedurefor the relay power board.

The [^] and[v] buttonsallow the increase/decrease of the current
set point by 1F or 0.5C.Specifically, in time-band operating mode
(indicated by the clock symbol), pressing the [^] and [v] buttons
temporarily modifies(overrides) the current set point. The
duration, in hours, is shown at the bottom of the display and being
decreased every hour

until the preset value elapses (parameter H8); the controller
will then return to the previous operating mode (time bands).During
the modification phase the display shows the temperature set point,
on the large display in the top left, in the place of the

measured temperature, if this is not already displayed on the
small display in the top right (this function can be selected
usingparameter H7)..Modifications are acknowledged by the
controller 5 seconds after releasing the buttons, when the related
symbol stops blinking.

4.2.3 Selecting the machine’s operating mode ([MODE] button)

Aria allows different operating modes of the air handling unit
described below:

OFF: the thermostat does not perform any control: however, it
prevents the temperature from dropping below the safety
lowlimit(see paragraph 4.2.4.1);

COOL: the thermostat controls cooling only;

HEAT: the thermostat controls heating only;

AUTO: heating and cooling control (automatic). The system
switches from one function to the other depending on the value

of the ambient temperature in respect to the set point; FAN:
ventilation only; you select the operating mode of the supply fan
among 1, 2, 3, AUTO and OFF by means of the [FAN] button.If you
press the MODE button in the time-band operating mode, it displays
the current operating mode for 5 seconds (indicatedby the
corresponding blinking writing in the place of the clock). In the
manual operating mode, instead, the operating mode isalways
shown.By pressing the button repeatedly the possible operating
modes for the machine selected alternates.

Fig. 4.2.4.1

The operating mode selected is acknowledged 5 seconds after
setting, when the related symbol stops blinking.4.2.3.1 Selects the
supply fan operating mode ([FAN] button, stand-alone version
only)Depending on the number of the supply fan speeds available and
the machine operating mode, the FAN button scrolls throughthe
following modes:

o OFF: supply fan off (available only when in simple
ventilation)o 1: supply fan constantly at speed 1

o 2: supply fan constantly at speed 2o 3: supply fan constantly
at speed 3o AUTO: supply fan switched on and off along with the
actuators

When selected speed 1, 2 and 3, the symbol corresponding to the
selected speed lights up for 5 seconds. Afterwards, the
numbercorresponding to the actual operating speed lights up; it may
temporary differs from the one selected due to parameter c8
(delaywhen varying the speed rates of the supply fan). Having set
AUTO operation, when the fan starts, the text AUTO also appears

next to the fan symbol.For details, see Output management.

4.2.4 Setting the temperature and humidity set points

4.2.4.1 Setting the temperature set point category ([SET]
button)

There are 3 possible situation available (unoccupied, comfort,
night-time) indicated by the relative symbols, as well as
themachine OFF limit category:

comfort set point (indicated by the symbol ): the room is
occupied, therefore a certain level of comfort isrequired

night-time set point (indicated by the symbol): the room is
occupied yet a lower level of comfort is required,obtained moving
the cooling and the heating stages a few degrees away from the
comfort set point (like having a neutralzone in between). This also
results in reduced operating noise and energy consumption.

unoccupied set point (indicated by the symbol ): typically used
when the room is not occupied. The temperaturedeviation with
respect to the comfort set point accepted is wider than the
night-time set point, as cooling andheating stages are engaged at
temperature values much higher and lower than the set point. Energy
consumption resultsminimized.

Pressing the SET button in manual operating mode (without clock)
changes the category currently used by the control. In time-band
operating mode, on the other hand, the category is automatically
set by the current program, as previously saved.If [^] and [v] are
pressed within 5 seconds of pressing SET (when category symbols are
flashing) the set points of the selectedcategory can be modified.
The default values for the various categories are:

category set (

C / F)

21 / 70

2 / 4

4 / 7

Tab. 4.2.5.1.1

Graphically the regulation obtained in the three different

When the unit is turned off (symbol visualized in the display)
or on in MODE=FAN, Aria will still start the heating stages

whenever ambient temperature drops below the low limit set with
parameter P4 (Carel default value is= 10C) in order to avoidany
damage in the room. In any case, this anti-freeze function can be
excluded using parameter R14.The right value of each category is
related to the season and the personal idea of comfort of each
user.

4.2.4.2 Setting the humidity set point ([SET] button for 3
seconds)

This can only be modified if the presence of the humidity probe
has been enabled, using S1=2. The set point is modified usingthe
[^] and [v] buttons (modifications are acknowledged by the
controller 5 seconds after releasing the buttons). The humidity

set point can also be set by parameter R5.

4.2.5 Programming the parameters

The user has numerous parameters available to customise the
operation of the control, making it adaptable to a wide range
ofneeds and applications. The parameters have been divided into 3
levels:1. DIRECT (D): directly accessible without protection
code;2. USER (U): accessible with protection code (installer
level);3. FACTORY (F): accessible with protection code at factory
level (manufacturer level).

4.2.5.1 Setting the DIRECT parameters ([SET]+[HOLD] buttons)

Fig. 4.2.6.1.1

The display shows the first of the main machine operating
parameters available. The parameters are scrolled using the [^]
and[v] buttons. Once having selected the parameter to be modified,
proceed as follows:

press the SET button to enter modifying mode, the selected
parameter flashes;

press the [^] and [v] buttons to modify the value of the
parameter;

press the SET button to confirm the modification.To exit
programming mode and accept the modifications to the parameters,
press the HOLD button.

To exit programming mode, and NOT accept the modifications to
the parameters, press the RESUME button, or wait for 1minute of
inactivity (the final 15 seconds are signalled by the flashing of
the characters on the display).

4.2.5.2 Setting the USER parameters (installer, [SET]+[MODE]
buttons)

These are the machine’s working parameters, and are
password-protected to avoid access by non-authorized persons. First
ofall the access code 22 must be entered using the [^] and [v]
buttons and confirmed using the SET button; when setting the
code,the right display shows the text Usr, telling the user what
branch they are in.

Fig. 4.2.6.2.1

Proceed then as per the setting of the DIRECT parameters.The
USER parameters also comprise the DIRECT parameters. The USER-only
parameters are signalled by the key symbol.

Fig. 4.2.6.2.2

Pressing the MODE button during the modification of a parameter
enables a DIRECT parameter to become a USER parameterand
vice-versa. On displaying the parameter in question the key symbol
will appear or disappear.

4.2.5.3 Setting the FACTORY parameters (configuration,
[SET]+[MODE] buttons for more than 3 seconds)

These are the machine’s configuration parameters. They are
protected by a separate code from the USER code, to allow
onlyspecific persons to access the data. First of all set the
access code 177 using the [^] and [v] buttons, and confirm it using
the SETbutton; when setting the code, the right display shows the
text Fac, telling the user what branch they are in.Proceed as per
the other parameters.

4.2.5.4 Setting the default parameters ([SET] + [RESUME] buttons
when powering the controller)

These are pressed before switching on the machine and held until
the settings have been entered, as signalled by the script
dEFdisplayed for 5 seconds. This operation allows the automatic
setting of all the parameters contained in the Table 7.1.1 at
their

default value (column def of the same table) except for the
following parameters: S1, S2, S3, R8, R14, R18, R27, F7, F8,
F9,F10, F11, F12, F13, H1, H2, H15, H16, P12, d12.

4.2.6 Using the Hardware key

4.2.6.1 Copying parameters from the removable hardware key to
the controller ([SET]+[^] buttons when powering Aria or

even only [^] button when powering Aria)

At the start of the operation the script CE appears; at the end
OK or NO appears, according to the result of the data transfer.

4.2.6.2 Copying parameters from the controller to the removable
hardware key ([SET]+[v] buttons when powering Aria)

At the start of the operation the script EC appear; at the end
OK or NO appear, according to the result of the data transfer.

4.2.7 Real time clock and time-bands

4.2.7.1 Setting the time ([CLOCK] button, version with built-in
clock only)

The value to be modified, that is, hours, minutes and day of the
week, is selected by pressing CLOCK repeatedly, modifiedusing [^]
and [v], and confirmed by pressing CLOCK again.

Pressing RESUME or after 60 seconds of inactivity, normal mode
is resumed, and the modifications entered are lost.

4.2.7.2 Time bands

The time bands are the intervals of time into which a 24 hour
day is divided; in each band, the operating mode of the unit can
be

selected, between: — — -There are 6 possible time bands for each
of the 7 days of the week.When programming the time bands, these
are indicated respectively by the letters t1-t2-t3-t4-t5-t6 on the
small display in the topright. When selecting one of the symbols,
that is, comfort, night-time or unoccupied, for a time band, the
unit will maintain theset temperature value throughout the interval
of time in question.If selecting the Standby symbol for a time
band, the unit will switch off throughout the interval of time in
question. If a set pointcategory symbol (comfort, night-time,
unoccupied) has then been selected for the following time band, the
unit will

automatically switch back on. When a Standby time band is
active, if the unit has not already been switched off using the
Modebutton, the Standby symbol will blink.Digital input ID3, if
used as a serious alarm, does not have any effect if Aria is OFF,
either due to the time bands or using theMode button. The unit can
be temporarily activated during a Standby time band by pressing the
Hold button (see par. 4.2.8.1).Pressing Resume returns to the
Standby time band (see par. 4.2.8.2).

4.2.7.3. Setting the time bands ([CLOCK] button more than 3
seconds)

The time bands refer only to temperature and not humidity
regulation which is always based on the same set point.The choice
among the symbols is always highlighted by having the currently
selected symbol flash and leaving the othersymbols constantly on;
[^] and [v] are used to change the selection, making the next
symbol in the sequence flash. To confirmthe selection and pass to
the following field use the CLOCK button.To set a program, after
having pressed the CLOCK button for more than 3 seconds, the
following steps must be performed:

set the program start day

set the start hour and minutes for the first band

set the temperature set point category for the band

after programming the band the symbols to continue () appear,
accompanied by the words cont and end

cont scrolls cyclically to the other bands, setting the start
hours and minutes for the second band and so on (the currentband
ends when the successive one starts)

end stops the programming for that day (thus cancelling any
unprogrammed bands)

after end or after having programmed the final band for the
current day, the day of the week programmed flashes followedby the
word copy. Use [^] and [v] to scroll to the other days, which flash
in turn, confirming the day using the CLOCKbutton, thus extending
same program to the selected days. The symbols cont (flashing) and
end and the script cont andmemo appear on the alphanumeric
field

use memo to exit from programming mode and enable time-band
operation. If there are days which have not been set, thesecontinue
to use the previous program. On pressing the RESUME button, on the
other hand, or after 1 minute of inactivity,the modifications
entered are lost.

use cont to program the remaining daysThe time interval
identified by time current band is shown on the display using the
clock symbol, divided into 1-hour sections.Thus, the time band from
3 to 7 oclock is indicated as follows

4.2.8 Alarm management and general functions

4.2.8.1 [HOLD] button.

This button has the following functions:

exits the parameter programming phase, saving the modifications
entered; on models with built in clock it passes from time-band to
manual operation; in such a situation the word HOLD appears

and the comfort set point resumed, independently from any
previous operating Set Point.

4.2.8.2 [RESUME] button.

This button has the following functions:

exits from the current programming phase without saving the
modifications;

exits from overriding the set point in time band operation
(models with real time clock);

exits from manual operation (HOLD) and returns to time band
operation (models with real time clock);

resumes the comfort set point on models without real time
clock;

silences the buzzer.

4.2.8.3 [RESUME] button for more than 3 seconds

Manually resets the active alarms, cancelling the message on the
display and de-energizing the alarm relay, if the alarmconditions
do not persist any more.

4.2.8.4 [^ ] + [v ] buttons simultaneouslyThis displays a value
marked R SP in the lower display; the value corresponds to the
effective start-up temperature of thedevices in the current
situation. For example, in cooling operation with Comfort
Set=21.0C, Night-time Set=4.0C (active), and

a compensation of +2.0C, the effective start-up point of the
compressors is 27.0C, that is, the value displayed by R SP. Thismay
be useful in the test phase.The firmware version is displayed by
holding the arrow buttons for more than 3 seconds.

5. OPERATION

5.1 General

The term SET POINT refers to the point which sets the position
of the controls working range within the interval of

measurement of the value being regulated. The set point thus
identifies the regulation value (temperature or humidity) that
thecontrol aims to maintain.

The term DIFFERENTIAL, on the other hand, refers to the value
assigned to the controls working range. Thus choosing anarrow
differential means that the control will operate very close to the
set point, with minimum variance from the set value, yetthis also
means an increase in the number of interventions of the control,
thus reducing the life-span of the systemscomponents. Vice-versa,
choosing a differential which is too wide, while providing system
stability, means that the values

reached during regulation may vary greatly from the set point.
The terms DIRECT and REVERSE indicate the two types ofregulation
logic for the device. The control uses direct logic when the
controlled measurement (e.g. temperature or humidity)

tends to increase, aiming to reach the desired value (set point)
(e.g. cooling, dehumidification); it uses reverse logic when
thecontrolled measurement tends to decrease, aiming, again, to
reach the desired value (set point)(e.g. heating,
humidification).Automatic (AUTO) operation refers to when the
device works in both direct or reverse logic according to the value
of thecontrolled measurement in respect to the set point.

The regulation set point for the Aria control is a lateral band
type, that is the band identified by the differential is aside
theset point, graphically on the right or on the left of the set
point (if we are respectively cooling or heating). Normally the
actuators

are deactivated when the value of the controlled measurement is
equal to the set point. For temperature regulation it is
howeverpossible to define a zone centred around the set point,
called the Neutral zone (see Fig. 5.1.1), inside of which the
actuatorsare already deactivated. This type of regulation is
proportional. The stand-alone version can also performProportional
+ Integral regulation (selected by parameter R19).

5.2 Stand-alone version

5.2.1 Proportional regulation algorithm

For the models with 1 regulation output, in direct operation
without neutral zone5.2.1.1, Aria activates the output when
thecontrolled measurement exceeds the value of set
point+differential and the output remains ON until the controlled
measurementdecreases to the value of the set point. In reverse
operation, still without neutral zone (Fig. 5.2.1.3), the device
activates theoutput when the controlled measurement falls below the
value of set point-differential and the output remains ON until
thecontrolled measurement rises to the value of the set point.

The Fig. no. 5.2.1.1 and 2 show respectively: direct without
neutral zone and direct with neutral zone.In AUTO operation (Fig.
5.1.1) the device can operate in both direct and reverse modes.. If
the system has one or twoauxiliary heaters, these (if enabled) are
activated according to the value of Haux set point (relative to the
current temperature setpoint) less the eventual neutral zone.

The Fig. no. 5.2.1.3 and 4 show respectively: reverse without
neutral zone and reverse with neutral zone.For the models with 2
regulation outputs, in direct operation without Neutral zone (Fig.
5.2.1.5) the device activates the first output

(OUT1) when the controlled measurement exceeds the value of set
point+1/2 differential; the second output is then activated
(OUT2)when the measurement exceeds the value of set
point+differential. The outputs remain ON until the controlled
measurement fallsbelow the value of set point+1/2differential (OUT2
goes off) and set point (OUT1 also goes off). In reverse operation
withoutNeutral zone (Fig. 5.2.1.7) the device activates the output
OUT1 when the controlled measurement falls below the value of set
point-1/2 differential; output OUT2 is also activated if the
measurement falls below the value of set point-differential. The
outputs remainON until the controlled measurement reaches the value
of set point-1/2 differential (OUT2 goes off) and set point (OUT1
goes off too).

The Fig. no. 5.2.1.7 and 8 show respectively: reverse without
neutral zone and reverse with neutral zone.

In Fig.5.2.1.9 provides a description of a heat pump unit with 2
compressors and 1 auxiliary heater in AUTO operation, with
thefollowing parameter settings: R1=18, R3=6, R4=2, R8=6, R9=2.

Humidity regulation (Fig.5.2.1.10) is very similar to the
temperature one; humidification (=reverse) is driven by a single
stage(relay OP, programmed accordingly, H2=0) while
dehumidification is performed by the available cooling stages
which, according

to the model, may be 2. Graphically a 2 compressor unit with
relay OP programmed to drive an humidifier is hereafter

5.2.2 Proportional + Integral regulation algorithm

If systems point of equilibrium is required to correspond to the
value of set point, more sophisticated regulation must be

imposed. Integral-type regulation must be added to proportional
regulation (available as standard). Integral-type regulation actson
the variation of the point of equilibrium from the set point,
aiming to reduce this to zero. The integral time must be set; a

typical value for this parameter, recommended as an initial
setting, is 600 seconds (10 minutes). The integral error is
notcalculated at all points of regulation, but rather only when the
measurement is located in the zone identified by the
differentialplus 10%. Outside of this zone, proportional regulation
only is performed.

Once PI regulation is activated, the control increases the
integral error, which is added to the proportional error, in every
instant:this means that the instrument is constantly acting to
reduce the total error being accumulated, with the result that the
point ofequilibrium is continuously being brought nearer to the
required set point.

5.2.3 Split operation

The machine model H1=14 allows the management of split-type
units, that is single-compressor heat pump with the possibilityto
manage a three-speed supply fan in the internal exchanger. The
ability to modify through ventilation the overall capacity —

0100% — of a single compressor based unit has led to the
development of temperature control which is different from the
oneavailable on the other selectable machine models (parameter H0).
Given the set point and the differential, the following control

logic has been preferred, considered as being more
efficient:

The compressor is in fact switched on at 50% of the temperature
differential (both in heating and cooling), with the supply
fanalready on at minimum speed; if the temperature continues to
rise the fact of switching the supply fan to speed two at 66%
and

speed three at 100% of differential allows the temperature to be
smoothly brought back within the set point.This system has the
following advantages:

on minimum temperature variations the supply fan is started (if
it has not be set for continuous operation) at minimum
speed,circulating the air in the environment, overcoming any
stratification of the air and providing a certain level of
comfort.

The compressor starts-up at 50% of the differential and no
longer at 100%, thus accelerating the overall response of
themachine to changes in ambient temperature.

When the compressor is running there are two further supply fan
steps which allow modulation of the refrigeration power,both on
increase and decrease of the temperature. In practice, the
efficiency of the machine is optimised accordingly thevariation of
thermal load.

This logic is of course valid in heating, cooling and automatic
operating modes. In addition, the neutral zone function is
still

available, if necessary; when enabled the start-up point of the
compressor is moved away from the set point of the value of
theneutral zone (as for other operating modes).The supply fan is
driven using 3 contacts, RL3, RL4 and RL5, activating the different
speeds in mutual exclusion:

at maximum speed relays RL4 and RL5 are off and relay RL3 is
energised.The reverse sequence is adopted for switching off.The
configuration H1=19 is a variation of H1=14, where the reverse
cycle valve and the heating element are absent; that is,
acooling-only unit.

5.2.4 Defrost managementThe defrost process (enabled if
parameter d1=1) is activated in the heat pump units during heating,
when the outside temperatureis very low and the coil of the
external heat exchanger is getting frozen. The start of the defrost
is determined by the drop in thetemperature of the external coil
(measured by probe B3) below a certain threshold (parameter d3) for
a minimum time(parameter d5) and brings about the immediate
shut-down of the external and supply fan and the inversion of the
reverse cyclevalve; the compressors remain on. If enabled by
parameter d8, the auxiliary heaters are also activated; in this
case the internal

fan remains on. The end of the defrost may be based on time
(parameter d2=0) or determined by the return of the
temperature(parameter d2=1) of the evaporator above a certain
threshold (parameter d4) or by the opening of digital input ID3
(parameterd2=2), in any case it must end within a maximum time
period (parameter d6). The minimum interval between two defrost
cyclesis set by parameter d7.

5.2.4.1 Forced defrost due to low outside temperature

If the temperature of the condenser (probe B3) falls below a
certain temperature value (d11), even if the minimum time
between

two defrosts has not elapsed (d7), a defrost is performed in any
case. At the end of the defrost, the time d7 restarts. The
programmay not perform more than one forced defrost at a time, and
in fact after having ended the first, it waits for the end of the
timebetween two defrosts, even if the outside temperature B3 is
lower than d11. Note that the forced defrost is valid if the
starttemperature d11 is lower than the normal setting, d3.

5.2.4.2 Manual defrost

Parameter d13 can be used to activate a manual defrost, if the
unit is operating in PdC mode. The defrost can be ended by
usingparameter d13 again (setting it to 0) or alternatively when a
temperature is reached (d4), or a maximum time elapses (d6), or
by

pressure switch on a digital input; in the latter three cases
parameter d13 changes from 1 to 0 automatically.

5.2.4.3 Compressor stops at start and end defrost

The compressor can be stopped at the start and the end of the
defrost cycles. The defrost start sequence is the following:1.
defrost request2. stop compressors3. wait time d94. reversing
valve

5. wait time d106. compressor starts and defrost is
performed.

The end defrost sequence is the following:1. end defrost
reached2. stop compressors3. wait time d94. reversing valve5. wait
time d106. compressor starts (if required by the system).

If one of the two times d9 or d10 is equal to 0, the compressor
is not stopped at the start or at the end.

5.2.4.4 Supply fan activation delay after defrost

If a defrost is performed without the support heaters (d8=0),
the supply fan remains off. To prevent the fan from starting

immediately at the end of the defrost, sending cold air into the
room, this can be delayed from the start of the compressors by
atime set using parameter F13.

5.2.4.5 Smart defrost cycles

The minimum time that must elapse between two defrosts, d7, can
be automatically decreased if the defrost requests are sofrequent
that the time d7 is considered too high. The time d7 is decreased
if two successive defrosts are started when the time d7has already
elapsed, that is, were already requested by the system before the
time elapsed, but were waiting for the start signal.

From this moment on, the time d7 is further decreased for each
defrost that starts when the time has already elapsed.
Vice-versa,

d7, after having been decreased, is increased a little at a time
if the defrosts do not start so frequently, that is, are requested
sometime after the time d7 has elapsed. The parameter defining the
value that the time between defrosts is increased or decreased byis
d10, and is expressed in minutes.

The time between defrosts may be decreased by a maximum of 60%
of the set value; if, for example, d7=20 minutes, it may
bedecreased by a maximum of 12 minutes, and the minimum value it
may assume is 8 minutes; it cannot be decreased below thislevel. If
d10=0, the function is disabled. When switching Aria off and on
again, or after a blackout, the time d7 is reset to itsoriginal
value . Below is a time diagram relating to the intelligent defrost
function, and to the compressor stops; as can be seen,

the temperature at the end of the defrost cycles is below the
activation threshold two consecutive times, which therefore
causesthe time d7 to be decreased.

5.2.5 Dehumidification management

The process of dehumidification is initiated by activating the
cooling actuators when the ambient humidity exceeds the humidityset
point + the corresponding differential, as described for direct
operation.In case two stages for cooling are available, the first
one is engaged at 50% differential, the second one at 100%.

The process can only occur if:

the machine selected is a conventional one, with cooling
(compressors) and heating actuators (heaters), that is
whenparameter H1 has a value between 5 and 10

the process has been enabled (parameter R7=1)

the humidity probe is present (parameter S1=2)

the temperature does not fall below the set point — differential
— possible neutral zone -0.5C (priority is given to temperature

regulation). In such event, the process of dehumidification is
interrupted to allow the ambient temperature to return to the
setpoint value; following this the process of dehumidification may
recommence.If more two compressors are available and compressors
rotation has been enabled, the actuator to be activated by
thedehumidification process is determined as described in the
section about paragraph Output management and under the heading

Compressor rotation.In the event of cooling calls along with
dehumidification requests, the number of cooling stages energized
will vary according

the higher of the two requests.Whenever in dehumidification
process, the symbol of ice will lit (only if any of the heating
actuators are not energized yet).

5.2.5.1 Dehumidification in Night-time or Unoccupied mode

In order to save energy, it may be useful to exclude
dehumidification during the night or in periods when the
environment beingclimate controlled is unoccupied. To do this, use
parameter H15. If H15=0 with the Night-time or Unoccupied set point
active,

dehumidification is not performed. If H15=1 dehumidification is
performed.

5.2.5.2 Dehumidification stop temperature

Dehumidification is in essence a cooling function that may lower
the ambient temperature. To prevent the temperature fromdecreasing
too much, a minimum temperature value is used to disable
dehumidification. This limit is: (Comfort SetDifferential0.5C);
below this temperature value, dehumidification is deactivated until
the temperature reaches the Comfort setpoint. The support heaters
can be activated during dehumidification to increase the
temperature; for all types of active set point

(Comfort, Night-time or Unoccupied) with dehumidification
enabled, the heaters are activated immediately below the Comfortset
point, in order to keep the temperature high.The diagram below
refers to the situation with the Night time or Unoccupied set point
active and dehumidification active. Thewhite steps refer to the
normal activation thresholds of the heaters based on temperature
(away from the set point due to the deadband), while the grey steps
indicate the activation of the heaters in the special case of
dehumidification.

5.2.6 Automatic set point compensation

The temperature set point can be modified automatically based on
the outside temperature value. If the outside temperaturereaches
values that may affect the operation of the unit, for example,
temperatures above 40 degrees in summer, the set point isworsened,
that is, increased; in this way, the level of comfort is decreased,
yet this has a positive effect on energy savings andthe life of the
machine. Another use of compensation is to maintain a maximum
difference between the ambient temperature andthe outside
temperature, to prevent, for example in shops, large differences
between the outside and the inside and consequent

irritation to those who enter and exit. The function is
described in the following diagram:

Cooling compensation starts when the outside temperature is
greater than: Set point+R3+4C. Following the example in thediagram,
with Set=25.0C and R3=3.0C, the compensation starts when the
outside temperature is greater than 31.0C (cooling

compensation) and less than 18.0C (heating compensation). The
intensity of the compensation can be set using parameters R23and
R24; these represent coefficients, and the higher their value, the
lower the compensation for the same outside temperaturevariation.
For example, setting R23=1 leads to a 1.0C increase in the set
point for each 1.0C increase in the outsidetemperature; setting
R24=2 leads to a 0.5C decrease in the set point for each 1.0C
decrease in the outside temperature. SettingR23 or R24 to zero
disables the corresponding compensation.

The maximum set point increase and decrease values are set using
parameters R25 and R26.The function is enabled using parameter
H16.N.B.For the correct use of the external probe, see the
paragraph: Using probes B2 and B3.

5.2.7 Free-cooling & Free-heating

The terms Free-cooling and Free-heating refer to the
introduction of outside air into the climate controlled
environment, infavourable temperature conditions, to either heat or
cool the environment and save energy. The outside air is introduced
into theroom by modulating the degree of opening of a damper,
controlled by two relays, one for opening and one for closing. The
relayactivation time is the total damper stroke time (parameter
L4). Whenever the control requests the total closing or opening of
thedamper, the system increases the energising time of the
corresponding relay by 25% to ensure complete closing or opening.
Ateach start-up, e.g. switching from Off mode to Auto mode, and
whenever Aria is powered, the damper is immediately fully

closed.Different options can be chosen (parameter R27):
free-cooling only, free-heating only, both enabled, and in addition
with orwithout compressors. The with or without compressors option
indicates that the compressors can or cannot start during
free-cooling / free-heating. In any case, if the outside
temperature conditions are not favourable, the free-cooling and
free-heatingfunctions are not activated and the compressors start
normally.

To prevent the introduction of outside air when the temperature
differs too much from the ambient temperature, there is amaximum
value for the difference between the two that, if exceeded,
disables the free-cooling and free-heating functions(parameter
R29); the functions are reset when the outside temperature is at
least 2C within the limit R29.

N.B.For the correct use of the external probe, see the ph. 5.2.8
Using probes B2 and B3.

5.2.8 Using probes B2 and B3

Three probes can be connected to ARIA: two NTC temperature
probes (B1 and B3) and one active humidity or temperature

probe (B2). The first NTC probe, B1, is designed to measure the
ambient air temperature.

The use of probes B2 and B3 changes automatically according to
the functions chosen.ACTIVE DEFROSTS (d1=1) ON UNIT PDC

AND/OR ACTIVE CONDENSATION (F7 different from 0)

Probe B3 is used for the defrost function and/or to manage the
condensation.

Probe B2 is used to measure the humidity if S1=2; Compensation,
Free-cooling and Free-heating can not be enabled.Probe B2 can be
used as the outside temperature measurement if S1=1; in this case
the Compensation, Free-cooling and Free-

heating functions can be enabled.

5.2.9 Output management

Compressor management.

When powering the controller, the compressor/s are activated
after an initial delay, set by parameter R21. During the normal

operation the optimisation of the starting is managed using an
intelligent activation program, as follows:

— when a compressor is activated, it is not shut-down within a
minimum running period (parameter c1);

— once the compressor has been shut-down, it is not re-activated
within a minimum stop period (parameter c2);

— a set time interval must elapse between two successive
start-ups of the same compressor (parameter c3).

— the second compressor, if present, may only be started after a
set interval (parameter c4) from the starting of the
firstcompressor;

— when there are 2 compressors, compressor rotation is enabled
if parameter R18 is set to 1.

Compressor rotation.Compressor rotation is a system which
controls compressor activation in such a way as to equalise
theiroperating times. The operating logic when 2 compressors are
activated is that the first to be started/stopped is the first to
be

stopped/started. When just one compressor is activated (in a
system with 2 compressors) this is done by alternating
thecompressors used. After a certain operating period, set by
parameter c7, the compressor maintenance required message is
displayed.

Reversing cycle valve management

This is controlled by the HEAT/COOL/AUTO setting on the terminal
or by digital input ID1 in the heat pump units.Heat: heating mode,
valve de-energized

Cool: cooling mode, valve energized

Auto: the state of the valve depends on the value of the ambient
temperature in respect to the set point. The state of thevalve is
changed, if required, at the moment the actuators are
activated.Parameter H14 can be used to choose the logic of the
relay dedicated to the reverse cycle valve. When the unit
isswitched off or when the set point has been reached, stopping the
devices, the valve remains in its existing position,until the next
request.

Heater management

When the instrument is configured for 2 or 3 heaters, SEQUENTIAL
heater management is used. The heaters are switched on/offin
sequence, with a time interval (parameter c8) between the
activation of heater 1, always activated first, heater 2,
alwaysactivated second and heater 3, always activated third. During
shut-down heater 3, if activated, is switched off first, then
heater 2and finally heater 1.

Auxiliary heater management

The auxiliary heater is activated, if enabled by parameter R10,
when the heat pump system is not able to maintain the
desiredtemperature, such as when the outside temperature is too
low. If this is an occasional occurrence, the compressors may be
lefton; otherwise they are shut-down (selected by parameter R11),
still respecting the time delays protection.

Supply fan management

The supply fan may feature from 1- to 3- speed operation. In
order to reduce current absorbed during start-up, the activation
of

the corresponding outputs is never simultaneous, but rather
delayed by parameter c8. The button Fan selects the fan
operatingmode (energized whenever at least one actuator is
operating or always ON).To reduce the stream of cool air in the
ambient, the supply fan is stopped while defrosting except when the
auxiliary heater areset to be energized in such situation; this is
performed in order to evacuate the energy provided. Using the MODE
button the

only ventilation mode can be selected (FAN script appears in the
alphanumeric field), disabling temperature and
humidityregulation.

Particularly, depending on the speeds of the fan available and
the machine model selected, the symbols 1, 2, 3 and auto next
to

the fan symbol, which alternate on pressing the FAN button, have
the following meaning:

Only ventilation mode (enabled by the MODE button):
