GENERAL FEATURES

Unit description

This series of water-water heat pumps satises 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 oor plants and high efciency 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 ow 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 inver-

sion) or through both systems actuated in sequence. When the unit is used in radiant oor plants, to avoid condensate generation, a room humidity sensor can be installed.

The internal programmer clock allows to dene different daily switching programs for heating, cooling and domestic hot water production.

The refrigerant circuit, contained in an extractable box to simplify 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 ow 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 exible. 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.

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 damper 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.

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 temperature (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 domestic 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 domestic 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 management of such components is possible through additional expansion modules which communicate with the unit by means of an internal bus and provide all the inputs and outputs required to full a complete system.

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

Options

The controller flexibility and the big number of options available allow to get, for each model, a lot of different configurations 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.

Option “Source side flow rate management”

Not reversible heat pump (IH) without options

Pump

Reversible heat pump (IP) without options

2 way valve

Source side ow rate management

Pump Allows the circulation of the water on the source side.

2 way valve

Page 9

GENERAL FEATURES

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 “Integrated 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.

Option “Domestic hot water production”

3 way valve

3 way valve with primary heat exchanger

3 way valve with secondary heat exchanger

Option “Plant buffer tank connections"

In this configuration the heat pump can heat or cool a buffer tank that increases the thermal inertia of the plant and operates as hydraulic separator.

NB If the integrated tank is used as buffer tank for the plant, it can not be used as tank for the domestic hot water production (see option "3 way valve and secondary heat exchanger").

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 3 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 (pVE-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]

Hmax 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.

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 current absorbed by the electrical heaters on that phase is never added to the current absorbed by the heat pump.

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.

Connections 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 ...

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

- the 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 (vibrations

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 excesive

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 L1 and L2 : V

1-2

= 390 V

line voltage between phases L2 and L3 : V

2-3

= 397 V

line voltage between phases L3 and L1 : V

CONTROL SYSTEM

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), user interface (E) and outdoor air temperature sensor (B). Such components are always supplied with the unit and allow to realize a climatic control based only on the outdoor air temperature.

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.

The remote control, supplied as an accessory, can be used, besides as user interface, also as room unit for the management of a zone both in heating and in cooling. The temperature sensor contained inside the remote control allows to detect the room temperature and to realize a climatic control based on the outdoor air temperature and on the room temperature.

If the heat pump controller manages a further heating zone, in order to realize a climatic control based on the outdoor air temperature and on the room temperature, it is necessary to add a remote thermostat (D) dedicated to that zone.

Heating and cooling circuits

The controller of the heat pump is able to manage up to two zones :

- zone 1 : heating and cooling

- zone 2 : only heating

The management of further zones, possibile by means of additional zone controllers, is not treated in this manual.

For each zone can be set :

- set point

- daily or weekly operating time table

- climatic curve

- room control sensor

The management of such zonesis performed by means of three independent distribution circuits.

The heating circuit 1 and the cooling circuit 1 control the same plant components (pump and mixing valve). Such circuits can be managed either as unmixed circuits or as mixed circuits (in this case for the mixing valve management the installation of a temperature sensor on the flow of the circuit is necessary).

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.

Set point setting

For each heating circuit 3 set points can be set : Comfort, Reduced and Frost Protecion. For each cooling circuit only one set point can be set : Comfort. The set points of the heating circuits are related one each other : the Comfort set point can not be lower than the Reduced set point, the Reduced set point can not be lower than the Frost Protection set point and the Frost Protection set point can not be lower than 4°C.

All the set points can be adjusted through the parameters. The Comfort set points of the heating circuit 1 and of the cooling circuit 1 can also be adjusted by means of the knob of the user interface. The Comfort set point of each circuit can also be adjusted by means of the knob of the remote control or of the remote thermostat assigned to that circuit (if present).

Heating integration with external heating source

It is possible to manage the activation of an external heating source to integrate the heating capacity supplied by the heat pump. The external source can be enabled only when the outdoor temperature is lower than a fixed limit (parameter 3700) in order to realize a bivalent operation.

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

Alarms table

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 or the parameter 6711 that activates the RESET function. 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.

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 kW 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.
