The choice and installation of components is the responsibility of the installer who should follow good working practice and current legislation. Before connecting the pipes, make sure they do not contain stones, sand, rust, dross or other foreign bodies which might damage the unit.

Construction of a bypass is recommended to enable the pipes to be washed through without having to disconnect the unit (see drain valves). The connection piping should be supported in such a way as to avoid it weighing on the unit.

Required components The following components must be installed in the water circuit:

1. A flow switch (inlet). The flow switch must be calibrated by the installer to a value equal to 70% of rated flow (obligatory).

2. An intake filter must be installed as close as possible to the evaporator and positioned to allow easy access for routine maintenance.

Recommended components

The following components should be installed in the water circuit:

1. Two pressure gauges with a suitable scale (intake and outlet);

2. Two vibration damper joints (intake and outlet);

3. Two shut off valves (normal in intake and calibrating in outlet);

4. Two thermometers (intake and outlet);

5. All the pipes must be insulated with suitable material to prevent the formation of condensate and heat loss. The insulating material must be a vapour barrier. Make sure that the control and shut off devices protrude from the insulation.

6. At the lowest points in the system, install drain valves for easy emptying.

7. At the highest points in the system, install automatic or manual air vent valves.

8. The unit is fitted as standard with an expansion vessel (8 liters); make sure this is correctly sized for the water content of the system and the expected operating temperature, otherwise install an additional expansion vessel.

Failure to install the flow switches will mean the heat exchangers are not protected in the event of no flow of liquid. The Manufacturer cannot be held liable for any damage to the unit and/or the system following the failure to install these devices or the filter.

The correct operation of the components that help ensure the safety of the appliance and the system should be checked regularly. Specifically, this involves cleaning the filters and checking the operation of the flow switches installed.

Make sure that the frost protection heaters on the heat exchanger are powered when the unit is off. Water flow to the chiller unit must conform to the values shown in the section on “General Technical Data”. The flow of water must be maintained constant during operation. The water content of the unit must be such as to avoid disturbing operation of the refrigerant circuits.

Condensate drain

The unit is fitted with condensate pan; this must be connected to a drain system to take away the water that forms, see the drawing. In heating mode the unit produces a significant quantity of condensate, which must be suitably drained. Proceed as follows:

• Connect the unit condensate drain

• Make sure the drain hose has a incline of at least 2 cm/m, without obstructions or choking.

• Connect the condensate drain hose to a rainwater drain. Do not connect to the sewage system as odours may be sucked up if the water in the drain trap evaporates.

• After connecting, check correct drainage of the condensate by pouring water into the pan.

• If necessary, suitably insulate the condensate drain hose.

• Condensate drainage must not cause problems to objects or people.

If the outside air temperature is less than 0°C, the condensate drained from the collection pan may freeze. The unit must be supported on a suitable structure or brackets to keep it off the ground, with a frost protection heater fitted on the drain line.

FILLING THE SYSTEM

- Before starting to fill, place the unit mains switch QF1 in the OFF position.

- Before filling, check that the system drain valve is closed.

- Open all system and terminal air vents.

- Open system shut off valves.

- Start filling by slowly opening the system water fill valve outside the unit.

- When water begins to leak out of the terminal air vent valves, close them and continue filling until the pressure gauge indicates a pressure of 1.5 bar.

The system must be filled to a pressure of between 1 and 2 bars. It is recommended that this operation be repeated after the unit has been operating for a number of hours. The pressure in the system should be checked regularly and if it drops below 1 bar, the water content should be topped-up. Check the tightness of the joints.

OFF

EMPTYING THE SYSTEM

- Before starting to empty, place switch QF1 in the “OFF” position

- Make sure the system fill/top-up water valve is closed.

- Open the drain valve outside the unit and all the installation and terminal air vent valves..

If the fluid in the circuit contains antifreeze, it should not be allowed to drain freely, as it is pollutant. It should be collected for possible reuse. When draining after heat pump operation, take care as the water may be hot (up to 50°).

ELECTRICAL CONNECTIONS

I A

The heat pumps must be installed downstream of a main switch (QF1, see wiring diagram), as required by the standards in force in the country where the unit is installed. Connection to the mains power supply and the connection of the flow switch to the corresponding terminals must be performed by authorised personnel in compliance with the standards in force. For all electrical work, refer to the electrical wiring diagrams in this manual. It is also recommended to check that:

- The characteristics of the mains electricity supply are adequate for the power ratings indicated in the electrical specifications below, also bearing in mind the possible use of other equipment at the same time.

Power to the unit must be turned on only after installation work (plumbing and electrical) has been completed. All electrical connections must be carried out by qualified personnel in accordance with legislation in force in the country concerned Respect instructions for connecting phase, neutral and earth conductors.. The power line should be fitted upstream with a suitable device to protect against short-circuits and leakage to earth, isolating the installation from other equipment.

Voltage must be within a tolerance of ±10% of the rated power supply voltage for the unit (for three phase units, the unbalance between the phases must not exceed 3%). If these parameters are not respected, contact the electricity supply company. For electrical connections, use double insulation cable in conformity with legislation in force in the country concerned.

A thermal overload switch and a lockable mains disconnect switch, in compliance with the CEI-EN standards (contact opening of at least 3mm), with adequate switching and residual current protection capacity based on the electrical data table shown below, must be installed as near as possible to the appliance.

An efficient earth connection is obligatory. The manufacturer cannot be held liable for any damage caused by the failure to correctly earth the unit. In the case of three phase units, ensure the phases are connected correctly.

Do not use water pipes to earth the unit.

WARNING

• The power supply current rating must be equal to the sum of the current drawn by the air-water heat pump and the current drawn by any other electrical appliances. If the contracted current rating is insufficient, make sure this is adapted accordingly.

• If the voltage is low and the air-water heat pump has difficulty starting, contact your electricity supplier to have the voltage increased.

How to connect the cables to the terminal Pay attention during wiring operations

• When stripping a main cable, always use special tools such as wire strippers. If no specific tool is available, strip the wires carefully using a knife, etc.

(1) Use crimp-on terminals with insulating sleeves as illus-

trated in the figure below for connecting the wires to the terminal block.

(2) Securely fasten the crimp-on terminals to the wires using

a special tool, so that the wires don’t come free.

(3) Use the cables specified, connect them securely and in

such a way that they don’t exert pressure on the terminals.

(4) Use a suitable screwdriver to tighten the screws on the

terminals. Don’t use damaged screwdrivers, otherwise the screw heads may also be damaged and the screws cannot be tightened correctly.

(5) Don’t over-tighten the screws on the terminals, otherwise

CONTROL AND OPERATING CHARACTERISTICS

Temperature control

The heating or cooling circuit water outlet temperature is calculated by the controller and depends on the following factors: A) system outlet set point compensation in heating or cool-

ing (see paragraph)

B) room temperature influence (see paragraph) C) minimum and maximum outlet temperature limit (see

paragraph)

D) room temperature set point

The compensation curves in HEATING are divided into:

• SYSTEM curve determines the general water outlet temperature to the terminal units.

• ZONE curve determines the water outlet temperature in the mixed circuit.

For systems configured with mixed zones, the SYSTEM curve and ZONE curve must be selected.

The system and zone curve work in cascading, the mixed zone curve may therefore not request a higher value than the one supplied by the system curve.

A) System water outlet temperature set point compen-

sation

The water outlet temperature set point in heating or cooling is calculated based on the outside temperature trend according to settable curves.

Water outlet set point compensation diagram in HEATING

The compensation curve in heating mode can be modified to allow correct heat pump operation depending on the heating system used (radiant panels, radiators, fan coils).

Example: Selecting heating curve 1,4 with an outside air temperature of -5°C gives a water outlet temperature of +55°C.

A heating curve that is too high gives an excessive outlet temperature, a curve that is too low may mean the desired room temperature is not reached.

The curve can be set separately for each zone, depending on the type of room terminal. The following compensation curves are recommended:

C) System outlet temperature limits in HEATING

These define the temperature limits (minimum and maximum) that can be requested from the circuit and never exceeded. In the figure the minimum limit is 30°C and the maximum is 40°. Between 30 and 40°C the outlet temperature will be able to vary based on the trend in outside temperature.

For systems configured with mixed zones, the limits for the SYSTEM curve and ZONE curve must be selected.

B) Room temperature influence in HEATING

The compensation curve determines the water outlet temperature in heating; this may then be corrected based on the difference between the desired room set point and the actual room temperature. The correction made to the outlet temperature depends on the “Room Authority” coefficient. The higher the value of the Room Authority the higher the correction to the system outlet temperature, and vice-versa.

This allows the outlet temperature to adapt quickly to changes in the conditions inside the room.

The function can only be ENABLED if the A5 room controller is positioned in the room and used to measure the reference temperature.

Set authority values for the SYSTEM equal to or greater than those for zones LT1, LT2, LT3.

Maximum room humidity compensation

The water outlet temperature set point, calculated based on the compensation curve, can be compensated according to the maximum relative humidity in the room. The water outlet temperature value can increase so as to avoid possible formation of condensate in the radiant cooling systems (underfloor, ceiling, wall, etc.).

If the relative humidity measured by the A5 room unit A5 exceeds the value set for parameter 012P, 0172, 0187, the water outlet temperature set point increases until reaching the maximum outlet temperature. The maximum outlet temperature is the set point calculated according to the compensation curve in cooling mode plus the value set for parameter 0158, 0173, 0188.

System pump operation

When reaching the system water set point, the compressor stops and the system pump is activated periodically, so as to minimise energy consumption. Pump operating time can be selected using parameter 0147, while the interval between one sniffing cycle and the next is set using parameter 0148. Intermittent activation of system pump operation can be selected using parameter 0143 (0= system pump always on to, 1=system pump activated at intervals).

In systems with fan coils, the time between one sniffing cycle and the next should be reduced in order to avoid cooling excessive of the water, and if the system water content is equal to the minimum value shown in the paragraph on "water connections", parameter 0143 should be set to 0.

Automatic mode changeover based on outside temperature

In mode, the operating mode (heating / cooling) changes automatically, avoiding the need for the user to change the mode manually. Mode changeover is based on the diagram shown in the figure.

The centre zone A corresponds to an area of inactivity, as the outside climate conditions mean neither heating nor cooling is required.

FROST PROTECTION

Frost protection based on system water temperature

The frost protection function is active even if the controller is in standby. To prevent the water freezing and damaging the plate heat exchanger, the microprocessor shuts down the compressor and activates the system heat exchanger heater if the temperature measured by the heat exchanger outlet temperature probe is than +4°C. The frost prevention temperature set point can only be modified by an authorised service centre, and only after verifying that the water circuit contains antifreeze. Tripping of this alarm shuts down the compressor but not the pump, which remains active. To reset normal operation, the water outlet temperature must rise to more than: +7°C on the system side. Reset is automatic.

Frost protection based on outside air temperature

Frost protection on the heating and domestic hot water circuits based on outside air temperature is always active, even when the heat pump is off. The system and domestic hot water pumps are activated when the outside air temperature falls below the value set for parameter 0141.

CONTROL AND OPERATING CHARACTERISTICS

U I A

Heat pump operation with fixed set point

Outlet water set point compensation using the compensation curves can be disabled. To enable fixed set point operation, set parameter 0152=0 and 0154=0 The heat pump will operate based on the fixed outlet set point defined by parameters 0153 (Heating) and 0155 (cooling).

The heat pump controller can select configurations for 15 different types of system by setting parameter 0101. The following table describes the system configurations available.

Configuration 0 does NOT require additional expansion modules Configurations from 1 to 3 require 1 additional N-EM1 expansion module Configurations from 4 to 11 require 2 additional N-EM1 expansion modules Configurations 12, 13 and 14 require 3 additional N-EM1 expansion modules The water connection and wiring diagrams for configurations from 1 to 14 are shown on the instruction sheet enclosed with the N-EM1 expansion module.

The parameters required for correct system operation can be set on the A5 room controller supplied with the heat pump.

SYSTEM CONFIGURATION

U I A

Heat pump connection to the system without low-loss header. Make sure the useful pressure head of the circulating pump on the unit is sufficient for the pressure drop in the system. If the minimum system content does not reach values shown in this manual, install an additional storage tank on the heat pump return pipe. No system configurations are required. For installations with heap pump connected directly to the system, without storage tanks and secondary pumps, parameter 011D must be set to 0. This means that heat pump operation will be managed based on the time bands.

Set the parameters following the sequence described in the table

SYSTEM emergency operation

If the heat pump is not working correctly or the compressor has shut down, emergency operation can be activated. Emergency operation involves heating the water using the electric heaters available on the system (outlet, storage tank). The compressor remains off.

To enable manual operation of system heaters, set parameter 0620 = 1 (manual)

DOMESTIC HOT WATER emergency operation

If the heat pump is not working correctly or the compressor has shut down, emergency operation can be activated. Emergency operation involves heating the domestic hot water using the electric heater inside the storage tank.

To enable manual operation of DHW storage heaters, set parameter 0202 = 1

SHUTTING DOWN FOR LONG PERIODS

After deactivating the heat pump:

- Disconnect the unit from the power supply.

- Make sure the remote keypad is in the “OFF” position.

- Place QF1 in the OFF position (see wiring diagram).

- Deactivate the indoor terminal units by placing the switch of each unit in the “OFF” position.

- Close the water valves.

If the outside temperature may fall below zero; there is the risk of freezing. The water circuit MUST BE EMPTIED AND CLOSED (if draining after operation in heat pump mode, beware that

the water may be hot), or antifreeze must be added in the proportion recommended by the manufacturer. It is recommended to use non-toxic food grade antifreeze, compliant with the standards in force in the countries where the unit is used, if domestic hot water production is also featured. If the mains switch is turned to “off” for more than four hours, after turning it on and before reactivating the unit, leave the power on but the unit deactivated for at least two hours to preheat the oil in the compressor sump.

Resetting alarms displayed by the board on the unit

Press the PUMP SW and RESET SW buttons at the same time for 5 seconds to reset the alarm. The alarms are reset automatically no operations are carried out for 5 minutes. While an error code is being displayed, holding the reset button for 10 seconds or more resets the alarm log.

Alarm log shown by the board on the unit

Press and hold the PUMP SW and RESET SW buttons together for 5 seconds until the log of error codes and the sequential number is shown. The PUMP SW button is used to select a maximum of 8 past error codes on the display. If there are no errors saved, the display shows "--".

UNSCHEDULED MAINTENANCE

Never perform any cleaning operations before having

disconnected the unit from the mains power supply. Make sure power is not connected before proceeding.

CHEMICAL WASHING

It is recommended to chemically flush the plate heat exchanger after every 3 years of operation. To perform this operation, contact a specialist technician.

REFRIGERANT GAS CHARGE

The chillers are filled with R410A refrigerant gas and tested in the factory. In normal conditions, there should be no need for the Technical Service to intervene to check the refrigerant gas. However, over time, small leaks may develop at the joints leading to loss of refrigerant and draining of the circuit, causing the unit to function poorly. In this case, the leaks of refrigerant must be identified and repaired and the refrigerant circuit recharged. Proceed as follows:

- Empty and dry the entire refrigerant circuit using a vacuum pump connected to the low and high pressure tap until the vacuometer reads about 10 Pa. Wait a couple of minutes and check that this value does not rise to more than 50 Pa.

- Connect the refrigerant gas cylinder or a filling cylinder to the low pressure line pressure gauge connection

- Charge the quantity of refrigerant indicated on the unit’s rating plate.

- Always check the superheating and subcooling values, which should be between 5 and 10°C and 4 and 8°C.

- After a couple of hours operation, check that the liquid indicator indicates a dry circuit (dry-green).

In the event of partial leaks, the circuit must be completely emptied before being recharged. The R410A refrigerant must only be charged in the liquid state. Operating conditions other than rated conditions may produce considerably different values. Tightness testing or identification of leaks must only be carried out using R410A refrigerant gas, checking with a suitable leak detector. The refrigerant circuit must not be charged with a refrigerant other than that indicated on the rating plate and in this manual. The use of a different refrigerant may cause serious damage to the compressor.

Oxygen, acetylene or other flammable or poisonous gases must never be used in the refrigerant circuit as they may cause explosion or poisoning. Oils other than those indicated must not be used. The use of different oil may cause serious damage to the compressor.

DISPOSAL

The unit must be disposed of according to the legislation

in force in the country concerned

SCHEDULED MAINTENANCE

Never perform any cleaning operations before having

disconnected the unit from the mains power supply. Make sure power is not connected before proceeding. Control maintenance is fundamental to maintain the efficiency of the unit both in terms of operation and energy consumption. The Technical Service maintenance plan must be observed, with an annual service which includes the following operations and checks:

- Filling of the water circuit;

- Presence of air bubbles in the water circuit;

- Efficiency of safety devices;

- Power supply voltage;

- Electrical power input;

- Tightness of electrical and water connections;

- Condition of the compressor contactor;

- Efficiency of the plate heat exchanger resistor;

- Verification of operating pressure, superheating and subcooling

- Efficiency of the compressor heater

- Cleaning of the finned coil every three months

- Cleaning of the fan grills

- Cleaning of condensate drain pan.

- Cleaning of water filters.

- Checking the ventilation openings on the base are free of leaves, bushes or anything else that may obstruct air flow.

For units installed near the sea, the intervals between maintenance should be halved.
