Unit description
GENERAL FEATURES
Unit identification code
This series of water-water heat pumps satisfies the heating, cooling and domestic hot water production requirements of residential plants of small and medium size.
All the units are suitable for indoor installation and can be applied to fan coil plants, radiant floor plants and high effi­ciency radiators plants.
As source both water (from well, river, lake…) or brine solu­tions (from geothermic probes) can be used.
The control system allows to manage not only the refrigerant circuit but the whole plant with the possibility to choose diffe­rent solutions both for the heating and cooling plant and for the domestic hot water management. The possibility of solar panels or other heating sources integration is also available.
The heating function optimizes the flow water temperature according both to the ambient temperature and to the outdoor temperature through climatic curves adaptable to the building features. It’s possible to manage a storage tank and two inde­pendent circuits (a direct one and a mixed one).
The domestic hot water management allows to control the three way valve, the storage tank and the anti-legionella cycles (if necessary).
The cooling function can be realized through “passive cooling” (free cooling) , through “active cooling” (refrigerant circuit inversion) or through both systems actuated in sequen­ce. When the unit is used in radiant floor plants, to avoid con­densate generation, a room humidity sensor can be installed.
The internal programmer clock allows to define different
daily switching programs for heating, cooling and domestic hot water production.
The refrigerant circuit, contained in an extractable box to sim- plify the maintenance operations, is equipped with rotary com­pressor mounted on damper supports, brazed plate heat exchangers, thermostatic expansion valve and reverse cycle valve (for reversible units). The circuit is protected by high and low pressure switches and flow switches on both the exchan­gers.
The outdoor structure and the refrigerant circuit box are both thermally and acoustically insulated in order to create a double wall against sound propagation and to allow the instal­lation in domestic places.
To avoid vibration propagation towards the hydraulic circuit the refrigerant circuit box is placed on damper supports and the connection pipes are flexible. Moreover all the hydraulic pipes are thermally insulated to avoid condensate generation.
All the units are accurately built and individually tested in the factory. Only electric and hydraulic connections are required for installation.
The codes that identify the units and the meaning of the letters used are described below.

GENERAL FEATURES
Description of components
External structure. Basement, lateral panels and frontal
panel, are completely thermally and acoustically insulated in order to minimize thermal losses and noise emissions in the surroundings. Accessibility to internal parts is possible remo­ving the frontal panel and the upper panel. For extraordinary manteinances also the rear panel can be removed.
Refrigerant circuit. It is contained inside an extractable box to simplify the maintenance operations. The box is placed on rubber vibration dampers and is connected to the hydraulic circuit through flexible pipes in order to avoid the propagation of the vibrations generated by the compressor outside the unit. The hermetic rotary compressor (1) is mounted on dam- per supports and is protected against overtemperatures and overcurrents. The heat exchangers on the plant side (2) and on the source side (3) are realized with brazed stainless steel plates
, properly insulated to avoid condensate generation and to minimize thermal losses, and protected by a flow switch that detects whatever water flow lack. The expansion device (4), a thermostatic expansion valve with external equalizer, allows the unit to adjust itself to the different operating conditions keeping steady the set superheating. The refrigerant circuit of each unit contains moreover solid core hermetic filter dryer (5) to restrain impurity and moisture residuals that could be present in the circuit, high and low pressure switches in order to assure the compressor to operate inside the permit­ted limits, 4 way reverse cycle valve (6) to allow operating mode change reversing the refrigerant flow (only for reversible
heat pumps), pressure connections SAE 5/16” - UNF 1/2” ­20 equipped with pin, gasket and blind nut, as required for the use of R410A refrigerant (they allow the complete check of the refrigerant circuit : compressor inlet pressure, compressor out­let pressure, thermostatic expansion valve upstream pressure and pressure drops accross the filter). All the pipes of the refri­gerant circuit are properly insulated to avoid condensate generation and to minimize thermal losses.
Hydraulic circuit. Both the hydraulic circuit on the plant side and on the source side are equipped with expansion vessel, air vents and drain valves. All the pipes are thermally insula­ted to avoid condensate generation and minimize thermal los­ses. The circuit on the plant side is moreover equipped with pressure safety valve, pressure gauge and three speed gland­less pump while the water flow rate on the source side can be adjusted by means of a three speed glandless pump or by means of a two way valve.
Electrical panel. It contains all the power, control and security components necessary to guarantee the unit to work properly. The unit is managed by a microprocessor controller to which all the electrical loads and the control devices are con­nected. The user interface, placed on the frontal panel of the unit, allows to view and to modify, if necessary, all the para­meters of the unit. All the units are supplied with an outdoor temperature sen- sor, to be installed outside, in order to realize the climatic con­trol.

GENERAL FEATURES
Control system
The microprocessor controller is able to manage not only the unit itself but also all that components of the plant which allow to realize a complete system.
The main functions of the control system are :
- room temperature control according to the outdoor tempe-
rature (climatic control)
- domestic hot water production (management of 3 way
valve, storage tank, anti legionella cycles…)
- management of a heating and/or cooling mixed circuit
(pump and 3 way mixing valve)
- management of a heating direct circuit (only pump)
- management of a storage tank for heating and/or cooling
- management of electrical heaters for heating and dome-
stic hot water (3 steps logic)
- solar panels integration
- passive cooling
- room humidity control for cooling with radiant systems
- internal programmer clock (for heating, cooling and dome-
stic hot water)
- digital input for electrical energy low tariff
- alarm memory management and diagnostic
- compressor and pump operating hour counter
- possibility to manage more units in cascade (maximum 16)
Besides the standard user interface present on all the units, wired or wireless remote thermostats are available which allow to control all the operating parameters of the unit and to acquire the temperature in the different zones in order to rea­lize a more precise and comfortable control.
The unit controller is able to manage a lot of different plant solutions enabling automatically the necessary control algorythms according to the components which have been connected.

The controller is able to manage up to two zones in heating (one by means of a mixed circuit and the other by means of a direct circuit) and one zone in cooling (by means of a mixed circuit).
It’s possible to realize more complex plants connecting to the heat pump controller further expansion modules in order to extend without limits the number of zones to be managed.
For each zone the following parameters can be set :
- set point
- daily or weekly operating time table
- climatic control curve
- room control sensor : it can be in common with the other zones or independent (in that case it’s necessary to install an additional room thermostat)

The hot water is diverted by the three way valve on an internal heat exchan­ger. An internal pump assures a correct domestic hot water flow through the other side of the heat exchanger.
3 way valve with secon­dary heat exchanger (for integrated tank)
The hot water is diverted by the three way valve in a tank integrated in the unit (accessory). The domestic hot water is generated istantaneously by means of an internal heat exchanger and a modulating pump.
Passive cooling
Allows to use the source to cool down the plant water without activating the compressor.
Integrative electrical heaters
Integrate or replace the heating power supplied by the heat pump and are managed by the unit controller with a 3 step logic.
Soft starter Reduces the compressor start current.
The controller flexibility and the big number of options availa­ble allow to get, for each model, a lot of different configura- tions that integrate inside the heat pump many components of the plant and allow to realize compact and tested installa­tions.
In order to select the right configuration it is necessary to defi­ne the type of plant to which the heat pump will be connected, both for what concerning the heating and cooling circuits, and for what concerning the domestic hot water management.

In this configuration the heat pump can be coupled to a domestic hot water tank equipped with a coil desi­gned for a maximum water tempera­ture between 55°C and 60°C. The anti legionella cycles have to be performed by means of electrical heaters placed on the heat pump outlet (see option “Integrative electri­cal heaters”) or directly inside the tank.
In this configuration the heat pump can be coupled to a domestic hot water tank without coil. The anti legionella cycles have to be performed by means of electrical heaters placed on the heat pump outlet (see option “Integrative electri­cal heaters”) or directly inside the tank.
In this configuration the heat pump can produce instantaneously the domestic hot water using the hot water stored in the tank integrated in the unit (see accessory “Domestic hot water production tank”). The temperature of the domestic hot water at the unit outlet is adjusted modulating the speed of the pump on the primary side. The anti legionella cycles are not necessary.

CONNECTIONS

Hydraulic connections
To design properly the hydraulic system respect the local safety regulations in force. It is always necessary to guarantee an appropriate water flow through the plate heat exchangers of the unit even if on both the hydraulic circuits (source side and plant side) is installed, as standard, a flow switch that stops the unit if the water flow rate is too low. To adjust the water flow rate through the heat exchangers modify the speed of the pump by means of the 3 speed selec­tor. For a more accurate adjustment it is reccomended the installation of a valve on the outlet of each circuit. It is also reccomended to install a filter on the inlet of each cir­cuit in order to avoid the entrance of foreign substances. The hydraulic circuit on the plant side is equipped with safety valve and expansion vessel. To mantain the circuit under pres­sure a self-filling group, that automatically fills the circuit, can be installed. The hydraulic circuit on the source side is equipped with expansion vessel. If it is used as a closed circuit it is neces­sary to install an adequate safety valve (maximum setting 6 bar).
Suggestions for the hydraulic plant realization
Prepare the pipes with the minimum possible number of bends in order to minimize pressure losses, and suitably sup­port them to prevent excessive stresses at the connections of the unit. Install shut-off valves near the components that need mainte­nance, to allow their replacement without having to drain the system. Provide manual or automatic valves in the highest part of the circuit to vent the air. Make sure there are no leaks before insulating the pipes and filling the system. In order to avoid condensate generation insulate all the pipes on the source side (and also on the plant side for reversible heat pumps) using steam barrier type material.
Brine solutions
When the unit is used as a brine-water heat pump, the source side hydraulic circuit must be filled with a brine solution able to guarantee a freezing temperature lower than the minimum expected operating temperature. In order to guarantee the unit to work inside the whole operating range declared, a free­zing temperature not higher than -15°C is required. The brine solution must be mixed before filling the circuit. All the components used on the source side hydraulic circuit must be suitable to work with the brine solution adopted. Galvanized steel pipes are not to be used.
Expansion vessels setting
All the units are equipped with expansion vessels (source side and plant side). The precharge pressure of the expansion vessel must be ade­quate to the total volume of the hydraulic circuit at which the unit is connected. The factory setting (p
VE-std
= 0,5 bar g) is the minimum value
necessary to avoid the presence of zones with a negative rela­tive pressure inside the hydraulic circuit and the risk of pump cavitation, supposing that no parts of the plant are placed at a higher level than the one at which the unit is installed. In that case the precharge pressure must be increased proportionally to the elevation of the highest part of the plant according to the following relation :
pVE= p
VE-std
+ H
max
/ 9,81
pVE: expansion vessel precharge pressure [bar g] H
max
elevation of the highest part of the plant referred to the unit installation level [m]
The maximum value of the precharge pressure is equal to the safety valve pressure set. Increasing the precharge pressure, the maximum plant volu­me supported by the expansion vessel of the unit is reduced :
VI= VVE· Ce· [ 1 - ( 1 + pVE) / ( 1 + pVS) ]
VI: plant volume supported by the expansion vessel [l] VVE: expansion vessel volume [l] Ce: expansion coefficient pVS: safety valve pressure set [bar g]
If the real plant volume is higher than such calculated volume, it is necessary to install an additional expansion vessel of appropriate volume.
Once the hydraulic circuit has been filled, the pressure at the expansion vessel must be slightly higher than the precharge pressure.
If parts of the plant are placed at a lower level than the one at which the unit is installed, verify that the components can with­stand the maximum pressure that can be present.

Electrical connections
The electrical wirings must be carried out by qualified person­nel according to the regulations in force at the installation time in the country of installation. Before starting any work on the electrical circuit make sure that the unit power supply line is disconnected at the start.
N.B. Refer to the electrical diagram enclosed in the unit.
Power supply system
The power cables of the heat pump power supply line must be connected to :
- for single phase power supply : from a single phase vol­tage system provided with neutral conductor and sepa­rated earth wire :
V = 230 V ± 10 %
f = 50 Hz
- for three phase power supply : from a symmetrical three phase voltage system provided with neutral conductor and separated earth wire :
V = 400 V ± 10 %
f = 50 Hz
The units are shipped completely factory wired and arranged for the connection to the power supply. The power cables must enter the unit through the holes on the rear panel and must be connected to the power supply termi­nals of the unit. The integrative electrical heaters (option) must be supplied by a dedicated power supply line to be connected to the power supply terminals inside the electrical board of the unit.
Heat pump power supply
The power supply cables must have an adequate section for the power absorbed by the unit and must be chosen in con­formity with the regulations in force. Design the power supply line, always referring to the total FLI and FLA values of the unit, taking into account the selected options (except the inte­grative electrical heaters) and the installed accessories.
Integrative electrical heaters power supply
The power supply cables must have an adequate section for the power absorbed by the only integrative electrical heaters and must be chosen in conformity with the regulations in force. It is possible to connect the integrative electrical heaters either to a single phase power supply or to a three phase power supply. If a three phase power supply is used, connecting to the ter­minal R the same phase used to supply the heat pump, the maximum absorbed current for each phase never exceeds 16A.
Upstream protection
An automatic switch suitable for ensuring protection against overcurrents and indirect contacts must be installed upstream each power supply line. Coordination between line switch must be carried out obser­ving the regulations in force on electrical safety, regarding the type of installation and the installation ambient conditions.
Connection available for the user
The electrical board of the heat pump contains some terminals dedicated to the connection of temperature probes, humidity probes, pumps, valves ... Carry out all the necessary connections in order to realize the desired plant following the instructions reported in the section “Inputs and outputs”.
ATTENTION
Carry out all the connections outside the heat pump avoiding the power cables and the probe cables to be coupled.

START UP
26
Start up
The following operations must be carried out only by properly trained personnel. To make the contractual warranty effective, start up must be carried out by authorized service centres. Before calling the service centre it is advisable to make sure that all the installation steps have been completed (positioning, elec­trical connections, hydraulic connections).
Preliminary checks before turning on
1. Verify that :
- the unit has not suffered visible damages due to transport or positioning
- the unit is placed on an horizontal surface able to bear its weight
- the minimum operating area are respected
- tha ambient conditions comply with the provided operating limits
- the hydraulic and electrical connections has been carried out correctly
2. Disconnect the unit power suply line at the start and make sure that :
- the unit power supply line complies with the regulations in force
- the screws, fastening the electrical cables to the components inside the electrical panel of the unit, are well tightened (vibra-
tions during transport phases could have caused some loosening)
3. Connect the unit power supply line and verify that :
- the voltage of the power supply line complies with the the nominal one of the unit
- for three phase power supply units, the unbalance between the phases is lower than 2% (a higher value produces an exce-
sive current input on one or more phases causing possible damages to the electrical components of the unit)
NOTE. Example of phase unbalance calculation
- Read the value of the three line voltages using a voltmeter :
line voltage between phases L1and L2: V
1-2
= 390 V
line voltage between phases L2and L3: V
2-3
= 397 V
line voltage between phases L3and L1: V
3-1
= 395 V
- Calculate the difference between the maximum and minimum value of the measured line voltages :
V

Control system configuration
The control system can be configured in different ways in order to adapt itself to the user needs and to the kind of plant mana­ged by the heat pump.
The simpler configuration consists of unit controller (A), outdoor air temperature sensor (B) and user interface (C). Such compo­nents are always supplied with the unit and allow to realize a cli­matic control based only on the outdoor air temperature.
Starting from this configuration it is possible to add, as accessories, remote thermostats (D) or remote controls (E) in order to realize a climatic control based also on the room temperature of each zone and to control the heat pump at a distance.
The communication between the devices of the control system can be carried out through wired or wireless connections. To rea­lize a wireless network are available, as accessories : wireless transmitter (F) to be connected to the heat pump controller, wire­less adaptor for outdoor temperature sensor (G) , wireless remote control (H) and wireless repeater (I) to be used to amplify the signal when the distance between the devices is large.

Heating and cooling circuits
The controller of the heat pump is able to manage two circuits in HEATING and one circuit in COOLING.
The management of further heating or cooling circuits, possible by means of additional expansion modules, is not treated in this manual.
Function Circuit name Type of circuit
Heating
HC1 Heating circuit 1 mixed
HCP Heating circuit P direct (unmixed)
Cooling CC1 Cooling circuit 1 mixed
The heating circuit 1 and the cooling circuit 1 control the same plant components (pump and mixing valve). For the mixing valve management a temperature sensor (probe B1) on the flow of the circuit must be install.
By means of these three circuits it is possible to manage up to two zones :
Zone 1 : heating through heating circuit 1
cooling through cooling circuit 1
Zone 2 : heating through heating circuit P
cooling not managed
The heating circuit P can also be managed together with the heating circuit 1, sharing set point and room temperature sensor. In that case zone 2 is not present. Heating circuit P management is defined by parameter 46 set on the user interface of the unit.
For each zone can be set :
- set point
- daily or weekly operating time table
- climatic curve
- room control sensor
The room sensor of each zone is contained inside the remote thermostat or the remote control. For each zone it is possible to install a remote control or a remote thermostat (it is not possible to install both). Each zone can operate also without room sen­sor (in that case the climatic control is based only on the outdoor air temperature).
If a remote thermostat or a remote control is present, the management of each zone is always possible also through the unit user interface.
The diagrams reported below show the different possible configurations of the system and the parameters to be set.

Control system devices installation
They should be located in the main room of the zone they manage taking into account the following criteria :
- the place of installation should be chosen so that the sensor can
measure the room temperature as accurately as possible without being influenced by the direct solar radiation or by other hot or cold sources (about 1,5 meters above the floor);
- in the case of wall mounting, enough clearance above the device
must remain, enabling it to be fitted and removed.
REMOTE THERMOSTAT AND REMOTE CONTROL ( WIRED OR WIRELESS )
The power supply of the remote thermostat and of the remote control is supplied by the mounting base. When the devices are removed from their base, power is cut off and the devices are out of operation. The wireless remote control is powered by three 1,5 V alkaline batteries type AA (LR06).

The wireless devices should be located in such a way that the transmission is as interference free as possible. The following criteria must be observed :
- do not place the devices in the vicinity of electrical cables,
strong magnetic fields or equipments as PC, televisions, micro wave ovens...
- do not place the devices near large metal structures or con-
structional elements with fine meshes as special glass or special concrete;
- the distance of the devices from the transmitter should not
exceed 30 meters or 2 floors.

ECO FUNCTIONS
Automatic summer/winter changeover
This function is used to switch on or off the heating mode in the course of the year according to the outdoor air temperature. It is possible to extend or to shorten the period of time during which the heating mode is active modifying the threshold of the out­door air temperature at which the changeover takes place. The threshold set is independent for each circuit (parameter 730 for heating circuit 1, parameter 1330 for heating circuit P). Increasing the threshold the heating mode will be switched on earlier and switched off later. To take into account the building thermal inertia the outdoor temperature is attenauted.
Automatic 24 hour heating limit
This function is used to switch on or off the heating mode in the course of the day according to the outdoor air temperature. This function allows, in the intermediate seasons (spring and autumn), to respond to sudden changes of the outdoor air temperature. It is possible to extend or to shorten the period of time during which the heating mode is active modifying the temperature thres­hold at which the changeover takes place. The threshold is calculated adding to the Comfort set point a differential. The diffe­rential set is independent for each circuit (parameter 732 for heating circuit 1, parameter 1332 for heating circuit P). Increasing the differential the heating mode will be switched on earlier and switched off later. To take into account the building thermal inertia the outdoor temperature is attenauted.

Heating circuits climatic curves setting
The climatic curves allow to calculate the flow temperature set point of each circuit according to the outdoor air temperature in order to keep the room temperature as near as pos­sible to the set value. The curves are referred to a room set point of 20°C . If the set point is modified, the curve automatically change to adapt themselves to the new value. It is possible to modify the parameters of the climatic curves in order to fit the features of the plant and of the building. The higher the slope of the curve, the higher is the change of the flow temperature set point for low values of the outdoor air temperature. If the room temperature is correct for high outdoor air temperature but is lower than the set point for low outdoor air temperature, the slope of the curve must be increased and vice versa. If on the other hand the room temperature is always lower or higher than the set point the curve must be translated without modifying its slope.

Alarms activation and reset
The controller is able to perform a complete diagnosis of the unit detecting all the operating faults and notifying different alarms. The activation of an alarm implies :
- involved consumers locked
- alarm icon shown on the display
- event recorded in the alarm history
To show the details about the active alarm press the INFO but­ton.
Alarms that can damage the unit or the plant require a manual reset that implies that the operator has to reset manually the controller. It is advisable to verify accurately the cause that ori­ginated the alarm and to make sure that the problem has been solved before restarting the unit. In any case the unit will restart only if the cause of the alarm has disappeared. For the manual reset alarms, pressing the INFO button, along with the details about the alarm, also the message “Reset ?” will appear. Press the OK button. When the message “Yes” blinks press again the OK button to confirm the alarm reset.
The less critical alarms have an automatic reset. As soon as the minimum compressor switch off time has elapsed the con­troller tries to reset the alarm. If the cause that originated the alarm has disappeared, the unit starts working again and the
alarm icon is no more shown on the display. Some of these alarms become manual reset alarms if the number of events in an hour exceeds a fixed threshold.
It is possible to reset the active alarms also through the RESET button. In that case the scheduled delays at the unit switch on are ignored avoiding undesired waiting times during commissioning or fault tracing. This function should NOT be used in normal operation.
Alarm history
The controller allows to save the last 10 alarms occured during the unit operation. For each event the following details are recorded :
- alarm code
- hour
- date
Such details can be displayed entering the “Errors” menu (parameters from 6800 to 6819). When the number of saved events is higher than 10 the follo­wing events are saved deleting the oldest alarms.

When the sensor is at the temperature of 25°C the electrical resistance measured at the sensor ends is 1 kfor the NTC 1K sensor and 10 kfor the NTC 10K sensors. The thermistor of these sensors has a negative temperature coefficient : the electrical resistance value decreases when the temperature increases.
In order to verify if a sensor is faulty or interrupted, check the correspondence between the resistance value in kand the temperature of the sensor in °C according to the table.
For a reliable check it is not necessary to control each single value, but some sample values are enough. If the instrument shows an infinite resistance the sensor is interrupted.

Maintenance
IMPORTANT
BEFORE CARRYING OUT MAINTENANCE OR CLEANING OPERATIONS MAKE SURE THE UNIT POWER SUPPLY IS DIS­CONNECTED. ANY ORDINARY OR EXTRAORDINARY MAINTENANCE OPERATION MUST BE CARRIED OUT BY SPECIA­LIZED AND AUTHORIZED PERSONNEL IN ORDER TO ENSURE COMPLIANCE WITH THE SAFETY REGULATIONS IN FORCE.
N.B. The unit switch on button placed on the frontal panel of the unit do NOT exclude the electrical voltage to all the circuits
contained inside the electrical panel of the unit. Always make sure that the power supply lines (of the heat pump and of the integrative electrical heaters) are disconnected at the start before carrying out any maintenance operation.
This section is extremely important for the efficient operation of the unit during the years. A few operations carried out periodi­cally can avoid the need to call specialized personnel. The operations to be carried out do not require particular technical kno­wledge and consist of simple checks of the components of the unit. Contact an authorized service center if maintenance is required.
Structure
To prevent noises and strange vibrations to rise make sure that the various steel parts are well fastened together and that the inspection panels are properly fixed to the unit. In case of oxidation, treat with paints, suitable to avoid or reduce the problem, the parts of the unit affected.
Hydraulic plant
Visually check that the hydraulic plant is leaks free and is pressurized. Verify there is no air in the circuit (acting on the air vents). Verify that the filters in the plant are clean.
Electrical plant
Verify that the power supply cable that connects the unit to the distribution panel is not affected by cuts, cracks or alterations that could compromise the insulation. Contact an authorized service center if maintenance is required. After a first period of time from the first start up and at every stop or seasonal start up carefully check that each electrical connection is well fixed.
