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.

FS

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)

GENERAL FEATURES

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

23

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.

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 :

Turning on

Press the unit switch on button placed on the frontal panel of the unit.
Start all the plant components necessary to guarantee an adequate water flow rate on the source hydraulic circuit (only if the
source side pump is not present).
Set the type of heat pump (water-water or brine-water) modifying the parameter 5800.
Activate the unit in heating or in cooling mode operating on the user interface or on the remote controls and insert a set point
suitable to require the unit to work.

CONTROL SYSTEM

27

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).

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.

Alarms

Note:

(1) A = automatic reset , M = manual reset , A / M = manual reset only if the number of events in an hour is higher than 3.

Sensors features

The temperature sensors used in the hydraulic circuit are
type NTC 10K (10 kΩ at 25°C).

The outdoor air sensor is type NTC 1K (1 kΩ at 25°C).

When the sensor is at the temperature of 25°C the electrical
resistance measured at the sensor ends is 1 kΩ for the NTC
1K sensor and 10 kΩ for 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 kΩ and 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.
