EDIT THE SET-POINT FROM 0-10V INPUT OR FROM RATIOMETRIC INPUT
Another type of adjustment allows you to edit the setpoint by adding (or subtracting) a value depending on the 0-10V input (if enabled). To
enable the function, set H22=40, and, if appropriate, edit the value of the parameter b15 (range 0-10), keeping in mind that if b20=0, 0-10Volt
input, if b20=1, ratiometric input.
-b20 = 0 with input at 0 Volt, the current setpoint: (Coo/Hea) setting – b15/2
-b20 = 0 with input at 5 Volt, the setpoint will be that set (Coo/Hea)
-b20= 0 with input at 10 Volt, the current setpoint: (Coo/Hea) setting + b15/2

7. CIRCULATOR
The circulator of the heat pump can be set in the following operating modes:
- operation on call by temperature controller
- operating on call by temperature controller with periodic activation;
14
i-32V5 Pompe di calore inverter aria/acqua con ventilatori assiali
- continuous operation (default);
The circulator is switched off immediately if:
-There is a manual reset pump block alarm, including the flow switch alarm;
-With remote input in standby or off, the pump (if running) is always switched off with a delay equal to P02 in tenths of a minute (default P02=2)
The circulator can be configured with P03 to operate independently from the compressor or on call.
0=continuous operation in heating/cooling mode(default P03=0)
1=operating on call by temperature controller
Note: with automatic reset flow switch alarm triggered, the circulator is on even if the compressor is off. The circulator is always on when the
antifreeze heaters are running and if operation of the hydraulic pump in antifreeze is enabled. Antifreeze operation is enabled if the regulation
temperature drops below P04 °C (default 5°C), and disables if the regulation temperature rises above P04+P05 °C (Default value P05=2,0°C).
7.1
CONTINUOUS OPERATION [P03=0] - Default
The circulator is only off with the unit OFF, in all other cases it is always on.
7.2
OPERATION ON CALL BY TEMPERATURE CONTROLLER [P03=1]
In this operating mode, the circulator is active on demand by the temperature controller, after a delay time of P01 seconds (default P01=30) from
when the pump switched on, the compressor switches on as well.
Whereas when switching off, the pump is deactivated after a delay time of P02 minutes (default P02=2) from when the compressor switches off.
With automatic reset flow switch alarm triggered, the circulator is on even if the compressor is off.

If P03=1, the circulator turns on periodically for a time defined by the parameter P17 (in seconds) after a count, lasting a time set by parameter
P16 (in minutes), activated when the pump switches off because temperature control fulfilled.
With automatic reset flow switch alarm triggered, the pump is on even if the compressor is off.
The periodical function is a suspended if the antifreeze protection trips.

PROPORTIONAL REGULATION OF THE CIRCULATOR
The speed of the circulator changes depending on the temperature difference between the inlet water and outlet water of the heat exchanger,
according to the diagram below, where:
• P07: Maximum speed = 100%
• P08: Minimum speed = (according to model)
• P09: modulating pump inlet/outlet water Delta T setting (°C) (according to model)
• P10: Modulating pump Delta = 3°C (default)

Function used to vent the system, with the circulator at maximum speed.
To enable the function:
• Controller OFF
• Access the parameters PRG ->PSS ->PRG -> (enter Service password)
• Press the UP and DOWN keys simultaneously for 3 seconds
The circulator switches on at maximum speed, and then switches off after 5 minutes.
The system venting cycle can be exited manually by pressing the MODE/ESC key, or by pressing the UP and DOWN keys simultaneously for 3
seconds.
During this function, the flow switch alarm is disabled, the maintenance technician must guarantee that there is water inside the system.
8. COMPRESSOR OR ACTIVATION LOGIC
The restart of compressors is in operation of a set point refered to the inlet water temperature. It is based on calculation of Si basa sul calcolo
di ∆T,set which is the difference between outlet water temperatures and inlet water temperatures, detected while the compressor for thermoregulation is turning off.

CONTROLLER FUNCTIONS
The following is a list of the functions which can be activated in the machine controller; not all of them can be selected simultaneously.
Values other than the default values can jeopardise proper operation of the unit. If in doubt on which value to set, contact our headquarters.
10.1
ANTIFREEZE PROTECTION HEATERS (IF KA ACCESSORY IS AVAILABLE)
If the optional KA kit is present, the function is active by default.
The water antifreeze heaters on the faces of the evaporator plates even activate with the machine off (but powered) when the delivery water
temperature drops below r02 °C (default 4°C) in “heating” mode or below r03 °C (default 4°C) in “cooling” mode or when switched “OFF”. The
heaters are switched off when the temperature measured by the outlet water probe exceeds r02+r06 in “heating” or r03+r06 in “cooling” or
when “OFF” (default value r06=2.0 °C).
The heating cable at the base of the machine activates when the outdoor air temperature drops below 3°C. It deactivates when the outdoor
temperature rises above 5°C.
10.2
ENABLING DOMESTIC HOT WATER PRODUCTION
To activate the domestic hot water functions, connect a probe to be placed inside the tank to terminals X17.1-X17.2 (enabled as analogue input).
The sanitary function must be enabled after positioning and connecting the temperature probe.

DHW temperature probe enabling
DHW valve control
If the domestic hot water temperature is lower than its setting (set by default at 48°C, edited by accessing the menu PRG->Set->SAN) the machine activates the DHW valve and the compressor is set at maximum frequency, starting modulation one degree before the setting and switching off one degree after. When the set point is reached, the valve goes back to the rest condition and the compressor starts to regulate normally.
Switching from utility water to domestic hot water, the working probe changes from “water outlet probe” to “DHW tank probe”. Switching from
winter mode to sanitary mode, the compressor does not switch off and is brought to the maximum frequency established by the controller,
whereas switching from summer mode to domestic hot water, the compressor is switched off and waits a safety time.
Defrosting is always carried out in winter mode on the utility side, and never on the domestic hot water tank.
NOTE:
-If H10 = 1/3/5. Switching off the unit by remote control (remote on-off, see paragraph 10.4.1) does not affect domestic hot water operation. The
unit goes to priority sanitary mode just powered on. The display on the machine shows the temperature detected by the probe inside the DHW
tank. When the sanitary cycle has finished, the display goes back to showing the water outlet probe temperature.
If the remote ON-OFF digital input (terminals 15.1 / 15.2) is open, with sanitary function enabled (H10=1 and H20=6), the wording “SAN” will
appear on the machine display. When the sanitary cycle has finished, the display goes back to showing “E00” indicating that the remote ON-OFF
contact is open.
-If H10 = 2/4/6, the remote on-off function disables domestic hot water production and operation of the heat pump in heatin and cooling mode,
system side.
10.2.1
MEMORISING THE PROBE IN HEATING MODE
Switching from utility water to domestic hot water, the working probe changes from “water outlet probe” to “DHW tank probe”. For this reason,
in heating mode, before entering sanitary mode, the last value read by the heat pump delivery probe is stored.
When sanitary temperature control is fulfilled, the system side temperature of reference goes back to that previously stored. The memory
function interrupts:
• when the temperature read by the probe becomes lower than the stored value;
• or when a time equal to b06 seconds (default b06 = 45) has elasped.
10.2.2
HEATING MODE ON DHW STORAGE TANK
If the parameter H130=1, the machine exploits the DHW storage tank even for central heating. In these conditions, the outlet of the DHW valve
is also enabled during operation in heating mode and not only in sanitary mode. The valve is deactivated during defrosting and in cooling mode.
When H130=1, the DHW integration heater can be enabled also to act as system integration heater: to do this, set r10=1 e r15=2 (for other r15
settings see Paragraph 10.6.3); furthermore no digital output must be set as system integration heater.
10.2.3
INSUFFICIENT HEAT EXCHANGE IN A DHW SYSTEM
During DHW production, if the heat pump flow probe detects a temperature higher than 60°C, the DHW valve output is de-energised (DO6), and
the value of the DHW probe at this time is recorded (Tsan,set).
-if the operation is San or Cool+San the compressor is stopped.
-If the operation is Heat+San, the system evaluates for b06 seconds whether there is a demand for heating from the system. If the system requires it, the compressor continues to work on the system, otherwise it is switched off.
-If the DHW resistor is present (e.g. DO3, H81=26), r15 = 0 or 1 and r24=2 or 3 it is activated until the DHW setpoint detected by the DHW probe
is met (and any offset).
The compressor restarts when the flow temperature of the heat pump falls below 60°C again and the temperature measured by the DHW probe
is lower than Tsan,set - 4°C.
10.3
REMOTE-CONTROLLED FUNCTIONS

The function is enabled by default on digital input ID 3 (terminals X15.1/X15.2).
Remove the terminal block jumper to place the unit in standby (the text “E00” appears on the controller display). When the contact closes, the
machine comes out of standby and the circulator switches on for 2 minutes.

DHW CALL FROM DIGITAL INPUT
Function which can be activated instead of managing the double setpoint.
If DHW mode is enabled, instead of using the temperature probe, the domestic hot water function can be activated by the opening/closing of
a digital input on the unit. This function is recommended when using two or more heat pumps in cascade hydronically connected to the same
domestic hot water storage tank; this way activation of the domestic hot water function is controlled by the tank probe connected to the first
unit, while the other units are enabled automatically by digital consent.
The system goes to sanitary mode when the digital input closes and exits DHW production when it opens.

SYSTEM WATER REMOTE PROBE
In some engineering solutions (e.g. heat pump in parallel to boiler on same hydronic circuit and shut off diverter valve) it could be necessary to
enable a system temperature probe so that the controller can correctly process the management.

Description
Enables plant remote probe
The plant remote probe controls the temperature of the heat pump only during the compressor start-up phase. Shutdown is managed by the
probe on the heat pump delivery line.
The table below illustrating operation of the system helps to understand this concept:
Operating mode

Temperature detected by the heat pump delivery probe > Coo setpoint+ 0.5°C
and
Temperature detected by system remote probe > Coo setpoint + b22
Nota: b22=5°C. See paragraph 13.
10.5
AUXILIARY HEATERS
In certain engineering solutions, it could be necessary to use an additional heater for the plant or for domestic hot water.
Parameter r24 must be set to define the operating mode of the additional heaters:
- r24=0 integration heaters not used;
- r24=1 only plant integration heater used;
- r24=2 only DHW integration heater used;
- r24=3 both plant and DHW integration heaters used.
10.5.1
PLANT HEATER
If the regulation temperature remains below water setpoint in heating (Hea) – 0.5°C for a time equal to r12 the integration heater is activated
according to operation of the machine in joint time slots or in substitution, as indicated in Paragraph 10.11.
The heater switches off when the setpoint is reached (also taking into account an offset set with parameters r29 or r30).
If the regulation temperature remains below the water setpoint minus r11 (°C) and the machine is blocked due to triggering of an alarm, the
heater switches on. It switches off when the machine exits the alarm block.

Function which can be activated instead of managing the plant heater
This is an additional resource for heating the domestic hot water storage tank if the compressor alone is not capable of fulfilling the request in
a reasonable time.
If domestic hot water production lasts longer than r16 (minutes) or if the machine blocks due to triggering of an alarm, the heater switches on.
It switches off when the unit finishes domestic hot water production (also taking into account an offset on the setpoint with parameter r31, as

SINGLE PLANT/DHW INTEGRATION HEATER
By configuring the DHW integration heater, it is possible to use this heater declared also as plant integration heater, setting the parameter r15=2
and r24=3.
In case of plant integration demand, the heater declared as DHW integration is activated, thus allowing to have a single integration heater for
plant, domestic hot water and plant under defrost.
10.6
INTEGRATION HEATER SELECTION MODE
The priority can be set in the order to activate the plant side and sanitary side integration heaters; specifically the configurations are:
1. r14=0 (default), the heaters can be activated simultaneously, if present;
2. r14=1, the heaters can be activated, excluding one another:
2.1. r20=0, priority to the plant (the DHW heater only switches on if the temperature control for the plant side heater is fulfilled);
2.2.r20=1, priority to DHW (the plant side heater only switches on if the temperature control for the sanitary side heater is fulfilled).
10.7
CIRCULATOR MANAGEMENT WITH HEATER ON
The circulator of the heat pump can be activated when the plant and/or DHW integration heaters are active with the compressors not running
(by substitution, by alarm or by integration in bracket II or III).
-r33 = 0: The circulator of the heat pump is activated on demand of the compressors or boiler,
-r33 = 1: The circulator of the heat pump is activated if the plant heater is active.
-r33 = 2: 2: The circulator of the heat pump is activated if the DHW heater is active.
-r33 = 3: The circulator of the heat pump is activated if the plant or DHW heater is active.
The circulator switches off after post-pumping (P02).

BOILER ENABLING
Function which can be activated instead of managing the double setpoint.
This is an additional resource to enable the boiler in integration or substitution of the heat pump.
Define the use mode by setting the parameter r23:
• r23=0 (default) boiler not used (operating priority of heaters);
• r23=1 only boiler on plant used (operating priority of heaters);
• r23=2 only DHW boiler used (operating priority of heaters);
• r23=3 DHW and plant boiler used (operating priority of heaters);
• r23=4 only boiler on plant with priority used (no heater operating priority);
• r23=5 only boiler in sanitary with priority used (no heater operating priority);
• r23=6 boiler on plant and in sanitary with priority used (no heater operating priority);
Define the supply of the boiler, setting parameter r32:
• r32 = 0: boiler without circulator with temperature control by heat pump,
• r32 = 1: boiler with autonomous circulator with temperature control by heat pump;
• r32 = 2: boiler without circulator with autonomous temperature control;
• r32 = 3: boiler with circulator with autonomous temperature control.

10.9 ACTIVATION OF INTEGRATION HEATERS AND BOILER IN JOINT OPERATION AND IN
SUBSTITUTION OF HEAT PUMP COMPRESSOR
The auxiliary parts that can be used for joint operation or for operation in substitution are:
• boiler
• plant integration heater
• DHW integration heater
Considering the operating modes in heating and/or DHW, there are 4 operating areas:

OPERATION IN SUBSTITUTION
If you need to change the values of the parameters r22, r28, r08, follow r22 ≥ r28 ≥ r08.
Setting r22=r28 allows you to eliminate the zone relative to joint operation bracket I; setting r28=r08 allows you to eliminate the zone relative to
joint operation bracket II; setting r22=r28=r08 allows you to eliminate both brackets relative to joint operation.
Do not modify value r08, as it could jeopardise operation of the unit
10.9.1
OPERATION IN HEAT PUMP MODE
Normale operation of the heat pump in which the integration heaters and-or the boiler only intervene when a heat pump alarm is triggered.
10.9.2
JOINT OPERATION (I BRACKET)
If the outdoor temperature is between r22 and r28, the compressor operates in synergy with the auxiliary heaters in winter or DHW mode.
In this operating bracket, first the heat pump is activated and after r12 minutes the plant side auxiliary heaters, or after r16 minutes the sanitary
side auxiliary heaters.
The intervention priorities are defined by the parameters r14, r20, r23, r24.
It goes back to normal operation if the outdoor temperature is greater than r22+1.0 (°C).
NOTE: In the joint operating bracket, the boiler is temperature controlled by the plant water remote probe (if enabled). In particular, if the
temperature detected by the remote probe is lower than the Hea setpoint, the boiler is switched on and then will go off when the temperature
detected by the remote probe is higher than the Hea setpoint. The heat pump follows the activation logic described in paragraph 10.5.
If the remote plant water probe is not enabled, the boiler will be managed by the delivery probe of the heat pump.
10.9.3
JOINT OPERATION (II BRACKET)
If the outdoor temperature is between r28 and r08, the compressor operates in synergy with the auxiliary heaters.
In this operating bracket, first the boiler is activated, then the heat pump and auxiliary heaters intervene after a time defined by r12 (minutes)
for the plant side and r16 (minutes) for the sanitary side
The intervention priorities are defined by the parameters r14, r20, r23, r24.
It goes back to normal operation if the temperature rises above r28+1.0 (°C).
Note: In the joint operating bracket, the boiler is temperature controlled by the plant water remote probe (if enabled). In particular, if the
temperature detected by the remote probe is lower than the Hea setpoint, the boiler is switched on and then will go off when the temperature
detected by the remote probe is higher than the Hea setpoint. The heat pump follows the activation logic described in paragraph 10.5.
If the remote plant water probe is not enabled, the boiler will be managed by the delivery probe of the heat pump.

10.9.4
OPERATION IN SUBSTITUTION
If the outdoor temperature drops below r08 use of the heat pump compressor will be inhibited.
- If the auxiliary system is composed of plant and/or DHW heaters, they are active in substitution of the compressor with defined times, r12
(minutes) for plant side and r16 (minutes) for sanitary side.
Whereas in the operation in substitution bracket, the integrations do not need to be enabled with r10 or r15 as the heaters need to operate in
substitution (and not in integration) of the heat pump (therefore simply select the type of use with the parameter r24).
- If the auxiliary system is a boiler with autonomous circulator (r32 = 1 or 3).
The circulator of the heat pump is off, after P01 (default 30 seconds) the boiler is enabled.
NOTE: With water side antifreeze protection, the pump used is activated (or remains active) anyhow.
- If the auxiliary system in substitution is a boiler with autonomous temperature control (r32 = 0 or 2).
The boiler is enabled regardless of the temperature control of the heat pump.
- If the auxiliary system in substitution is a boiler without circulator (r32 = 0 or 2).
The circulator of the heat pump is on when the boiler is enabled.
The compressor switches back on if the temperature rises above r08+ r09 (°C) (r09=1.0 °C by default).
10.10 OPERATING BRACKETS - ACTIVATION OF INTEGRATION HEATERS (PLANT REMOTE
WATER PROBE NOT ENABLED)
The possible configurations of the integration parameters are listed in tables 1,2,3 and 4 shown below, divided by operating brackets (the operating modes and possible values of the parameters are indicated in the “STATUS” boxes and in the parameters “rxx” so that a given order
of intervention of the integrations occurs in a certain operating mode of the unit; other statuses and values of the parameters can be selected
instead and therefore they are provided in the same cell separated by the symbol ”/”).

10.10.1 AUXILIARY SYSTEMS OFFSET MANAGEMENT
Lastly you may establish that the boiler and/or integration heaters (according to the resources and selected priorities) have a setpoint in heating
mode and in sanitary mode higher than that of the heat pump. This is achieved by setting an offset on the following setpoints:
• r29 = First setpoint temperature offset for boiler and plant heaters (G02);
• r30 = Second setpoint temperature offset for boiler and plant heater (G05);
• r31 = Temperature offset for boiler and DHW heaters (G03);
This way the heat pump stops at the setpoint (G02,G03,G05) and the temperature difference, according to the set outset, will be supplied by
the boiler and/or heaters.
10.11 WARNINGS
If the double setpoint function is not active, one of the following warnings can be configured.
10.11.1 PLANT SEASON
A digital output can be configured indicating the operating season of the unit, plant side.
The output is active in summer mode, while it is deactivated in OFF or heating mode.
During DHW production and defrosting, the output maintains the setting of the source season.

10.12 DEFROST CYCLE
The defrost cycle is only active in heat pump mode and is used to prevent the formation of ice on the surface of the air/air coil. The formation of
ice on the evaporator, which is quite frequent with very low outdoor temperatures, in addition to considerably downgrading the thermodynamic
performance of the unit, also risks damaging the unit itself.
If the unit is switched off by remote control during defrosting, the heat pump finishes defrosting and then places itself in off mode via remote

control.
10.13 COMPRESSOR CRANKCASE HEATER
The crankcase heater is activated if the compressor has been off for at least 30 minutes and if the discharge temperature is below a certain
threshold of 20 °C (with hysteresis of 2.0°C). The crankcase heater is disabled when the compressor starts back up.
10.14 DOUBLE SET-POINT
This function introduces a second working set-point on the plant side, both in cooling and heating mode.
The user terminal board allows a consent to be connected to switch from the first to the second set-point and configured at digital input DI9 with

12.2 MANAGEMENT OF SECONDARY CIRCULATOR/BOOSTER PUMP (WITH ROOM THERMOSTAT)
It allows the management of a secondary or booster circulator to serve the plant.
A room thermostat (N.C.) must be configured appropriately.
- Thermostat closed contact -> The secondary circulator is activated;
- Thermostat open contact -> The secondary circulator is off with a delay given by P02 (post-pumping).

Determination of setpoint
The setpoint on which to perform regulation is given by rCO or rHE respectively in cooling and heating mode. If dynamic compensation of the
setpoint is enabled (b08=1), then the setpoint will be corrected the same way as the heat pump/chiller.
The maximum and minimum value reached by the compensation are not controlled. Therefore the parameters must be configured so that the
setpoints are not brought to unwanted values outside of the allowed work ranges.
12.3.2
Radiant panels circuit pump
The radiant panels circuit pump is activated when there is a thermostat call and switches off with a delay of P02 from when the thermostat call
ceases.
12.3.3
Mixer valve
The mixer valve is regulated by means of specific PID which strives to maintain the delivery temperature of the radiant panel at the setpoint
value.
To manage the contact valve, there is a positioning phase at “0”, the output DO1E is active until the all open limit switch is reached, time defined
by i01 (140 seconds).
When i01 seconds have elapsed, the output DO 1E is deactivated. Then the valve goes to the recirculation position, activating output DO 2E for
a limit switch closing time i01.
When i01 seconds have elapsed, the output DO 2E is deactivated. Then the valve goes to the regulation position, which is corrected every i02
(10 seconds).
When complete closure is requested, the output DO 2E is activated for a time equal to 20% of i01 to guarantee complete closure and to eliminate
any positioning errors accumulated over time.

Activation of solar circulator
Solar management is also active with the unit off.
The solar circulator is active in both of the following conditions are met:
• The temperature of the solar collector is higher than that defined by parameter S13 (default 40°C), the solar circulator is activated;
• The temperature difference between the solar collector and that of the solar storage tank is higher than the parameter S02 (default 6°C).
12.4.2
Collector protection
If the temperature of the collector exceeds parameter S04 (default 110°C), the solar circulator is periodically on intermittently with the times
set in:
• S05 = time ON (default 15 seconds);
• S06 = time OFF (default 15 seconds).
As hysteresis to exit the protection condition use S08 (default 2°C).
This protection is guaranteed even with the machine Off.
12.4.3
Collector overtemperature alarm
If the collector probe exceeds the value of parameter S12 (default 130°C), there is an alarm condition E10 which blocks the solar circulator. The
hysteresis to return from the alarm condition is given by parameter S08 (default 2°C).
If an alarm is triggered, operation of the heat pump is guaranteed.
12.4.4
DHW overtemperature alarm
If the temperature of the DHW storage tank exceeds the parameter S10 (default 80°C), the alarm E50 is triggered.
The hysteresis to return from the alarm condition is given by parameter S11 (default 2°C).
If an alarm is triggered, operation of the heat pump is guaranteed.
12.4.5
Solar exhaust valve
If alarms E10 and E50 are triggered simultaneously, the solar exhaust valve will be activated.
It is recommended to connect the output of terminals 8.1 (phase) – 8.2 (neutral) to a timed relay to manage the flow of the exhaust valve. If
any doubts arise, contact our headquarters.
12.4.6
Dissipation of solar tank heat
The solar circulator runs to dissipate excess heat in the storage tank by exploiting the solar collector if both of the following conditions are met:
-The temperature of the DHW storage tank is higher than parameter S15 (default 60°C);
-The temperature of the solar collector is lower than 35°C (parameter S13 – parameter S14).
-The solar collector is off when at least one of the following conditions is met:
-The temperature of the DHW storage tank is lower than parameter S15 (default 60°C).
-The temperature of the collector exceeds the parameter S13 (default 40°C), as conditions are no longer in place for proper dissipation of the
heat.
12.4.7
Antifreeze
Function active if the parameter S01 = 1.
If the temperature of the solar collector is lower than parameter S07 (default 5°C), the solar circulator is activated in antifreeze mode.
This protection is only enabled with the machine Off.
The function is inhibited if the temperature of the DHW storage tank is lower than the value defined in parameter S16 (default 20°C).
This regulator also works with the unit Off.
29
i-32V5 Pompe di calore inverter aria/acqua con ventilatori assiali
Setting the parameter S01 = 2, the antifreeze function is never active (for example because the solar plant is supplied with glycol).
Be careful as enabling this function could damage the entire system.
Note:
• Solar integration is NOT managed if the controller of the unit is OFF.
• The remote digital input OFF has no effect on solar management.
• During first ignition, check that the probe of the solar collector measures a temperature lower than 160°C and that this temperature corresponds to that read on the controller of the internal unit.
• Solar circulator live output 230V ac, 50Hz, 2A (AC1).
• For higher absorptions, connect the output to the contactor coil.
• Factory-set parameters for solar management, any other configurations are the responsibility of the user and/or installer. The company
excludes any contractual and extra contractual liability for damage caused to persons, animals or objects, by incorrect installation, setting
and maintenance, improper use of the equipment, and the partial or superficial reading of the information contained in this manual.

The water side flow switch is already installed inside the unit and MUST NOT be tampered with or bypassed in any way. The flow switch is bypassed for 10 seconds after the unit is switched on. When the bypass time has elapsed, you must evaluate the status of the digital input, if active,
the flow is considered present.
If the flow is found to be missing for 5 seconds, the alarm is triggered and the circulator switches on for 120 seconds
If the alarm triggers more than 3 times an hour, it must be reset manually.
The alarm does not trigger in the following conditions:
• During domestic hot water production;
• During the plant venting cycle function.
14.2
[E018] HIGH-TEMPERATURE
If the water delivery probe detects a value higher than 65°C for longer than 50 seconds, the alarm is active. It deactivates when the temperature
returns below 62°C.
14.3
[E020] INVERTER TRASDUCTORS
For compressor enabled for more than 150 seconds, the suction pressure probe detect a pressure higher than the condensation pressure probe,
the alarm displayed is E020. The alarm is not resettable (it is necessary to cut the power supply to eliminate the alarm).
This alarm is not in defrosting mode.
14.4
[E005] ANTIFREEZE
If the outlet water probe has a value lower than A08 (3°C), the alarm is active. It deactivates if the temperature recorded by the probe is higher
than +6°C. The alarm is bypassed for 120 seconds from switch on in heating mode.
14.5
[E611÷E681] PROBE ALARMS
The alarm is triggered if any connected or enabled probe is short-circuited or interrupted.
The alarm also triggers if the upper limit (100°C) or the lower limit (-50°C) of the probes is exceeded. A probe figured as sanitary probe will not
trigger any alarms if domestic hot water is not enabled.
NOTE:
If the pressure switch on the machine detects a pressure exceeding 42.8 bar the driver and the compressor are powered off and probe error E641
is displayed (Compressor discharge probe fault).
The alarm is cleared when the pressure drops below 34 bar.
14.6
[E801] TIMEOUT INVERTER
When the machine’s controller does not communicate with the driver board of the compressor, a timeout alarm is triggered to avoid losing
control of the system.
14.7
[E851 ÷E971] INVERTER
The inverter has its own list of alarms.
14.8
[E00] REMOTE ON/OFF (WARNING)
If the unit is controlled by a remote digital input. See par. 10.4.1
14.9
[E001] HIGH-PRESSURE
If the pressure transducer on the unit detects a pressure higher than 41.5 bar the alarm is triggered.
In this case the compressor is blocked immediately. The alarm is reset when the pressure drops below 32.5 bar. If the alarm triggers more than
3 times an hour, it must be reset manually.
14.10 [E002] LOW-PRESSURE
In chiller mode, if the pressure transducer on the unit detects a pressure lower than 3.5 bar, the alarm is triggered.
In heat pump mode, if the pressure transducer on the unit detects a pressure lower than 1.3 bar, the alarm is triggered.
The alarm is reset when the pressure rises 2.0 bar above the triggering threshold.
A bypass time of 60 seconds is counted every time the compressor is activated.
When the alarm is triggered, it blocks the compressors of the circuit.
The alarm is reset manually if it triggers 3 times an hour.
14.11 [E008] DRIVER LIMITATION
If the compressor does not reach the speed at the intended ramp value within 30 minutes, the alarm is triggered and the compressor switches
off for safety purposes.
The alarm is reset manually if it triggers 3 times an hour.
14.12 [E041] 4-WAY VALVE
Manually reset alarm, it identifies malfunctioning of the 4-way reversing valve.
The alarm does not trigger for a bypass time of approximately 180 seconds from start-up of the compressor.
• In heating and sanitary mode, the alarm is triggered when, the bypass time having elapsed, the water delivery temperature is lower than
the water return temperature of the heat pump - 1°C.
• In cooling mode, the alarm is triggered when, the bypass time having elapsed, the water delivery temperature is higher than the water
return temperature of the heat pump + 1°C.
