GENERAL FEATURES

The user interface consists of a wired remote controller (up to 50 m from the unit) which allows the management of:

- HEATING AND COOLING SYSTEM, where the heat pump is the sole energy source. The unit, if activated in heat or cool mode, works by modulating the frequency of the compressor to maintain the temperature of the produced water to the setpoint value set by the controller. Through parameter you can use the remote controller (eg. For single-zone systems) as a room thermostat.

- DOMESTIC HOT WATER PRODUCTION (DHW). The unit is activated in a heatt mode to keep the temperature of a DHW tank (not supplied) to the setpoint value. It requires a 3-way diverter valve (not supplied) and a temperature sensor (T5 probe, L = 10m, provided) to be inserted into one well of the DHW tank.

- ADDITIONAL SOURCES OF ENERGY (boiler or electrical heater). Depending on the parameters set, these sources can be activated in integration or replacement of the heat pump

when the system is used for space heating or for DHW production. The controller also activate additional energy sources in case the heat pump is not working.

- ELECTRIC HEATER OF THE DHW TANK. The controller can manage the activation of an electric heater inserted in the DHW tank as a heat integration to the heat pump, for disinfecting function, or as a source of energy reserve for DHW production in case the heat pump is not working. FAST DHW. This function can be activated manually and it allows you to give priority to DHW production by activating all energy sources (heat pumps, electric heaters, boiler) available for DHW heating to bring in the shortest time possible the DHW tank to the setpoint required.

- DISINFECT FUNCTION. You can set from the controller weekly cycles for disinfecting the water in the Dhw tank. In order to successfully execute these cycles, the heat pump must be integrated with DHW electric heater or boiler.

- SILENT MODE. If active it allows a reduction of the maximum frequency of the compressor and of the fan speed in order to reduce the noise emitted and the power absorbed by the unit. There are 2 levels of silencing. Through time programming, you can deﬁ ne for 2 daily time bands the desired silent level (eg. during the night).

- ON / OFF using an external contact. The unit can be turned on and off (eg. thermostat / remote switch) via an external contact: in this case the unit will operate in the mode set by the controller keyboard.

- HEAT / COOL via external contacts. The unit can be activated in heat or cool mode via two external contacts (eg. thermostat that manages the heat and cool demand / remote switch).

- ECO MODE. Possibility to deﬁ ne in heat mode a time band within which the heat pump works with a sliding setpoint deﬁ ned by the chosen climatic curve. 8 climatic curves are available for low temperature systems (radiant ﬂ oor) and 8 climatic curves for fan coil or radiator systems)

- WEEKLY SCHEDULING. It allows a schedulation of 6 time bands for each day of the week: for each time band it is possible to deﬁ ne the mode (COOL / HEAT / DHW) and the required setpoint.

- Detailed alarms diagnostics with alarms history.

- Display of all operating parameters.

Make sure there is enough room to do the installation

■ Prepare a water drainage channel around the foundation, to drain waste water from around the unit.

■ If water does not easily drain from the unit, mount the unit on a foundation of concrete blocks, etc. (the height of the foundation should be about 100 mm.

■ If you install the unit on a frame, please install a waterproof plate (about 100 mm) on the underside of the unit to prevent water from coming in from the low side.

■ When installing the unit in a place frequently exposed to snow, pay special attention to elevate the foundation as high as possible.

■ In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is not affected by the snow (if necessary construct a lateral canopy).

■ As the outdoor temperature is measured via the outdoor unit air thermistor, make sure to install the outdoor unit in the shade, or a canopy should be constracted to avoid direct sunlight, so that it is not influenced by the sun’s heat, otherwise protection may be possible to the unit.

■ Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installation.

■ In accordance with the foundation drawing in the figure, fix the unit securely by means of the foundation bolts. (Prepare four sets

each of Ø10 Expansion bolts, nuts and washers which are readily available on the market.)

■ It is best to screw in the foundation bolts until their length is 20 mm from the foundation surface.

When installing the unit in a place exposed to strong wind, pay special attention to the following.

Set the outlet side at a right angle to the direction of the wind. Strong winds of >5 m/s or more blowing against the unit's air outlet causes a short circuit (suction of discharge air), and this may have the following consequences:

- Deterioration of the operational capacity.

- Frequent frost acceleration in heating operation.

- Disruption of operation due to rise of high pressure.

- When a strong wind blows continuously on the front of the unit, the fan can start rotating very fast until it breaks.

Cooling connections indoor unit

Comply with the following indications when connecting the cooling pipes:

• Match the ends of the previously flared pipe with those of the connections on the indoor units or on the cocks of the outdoor units.

• Tighten the union by hand and then torque it with the aid of an adequate wrench (it is advisable to use a fox wedge to prevent tensions from being created on the pipes).

INSTALLATION

Limits to the length and height difference of refrigerant pipes

The length of the refrigerant pipes between the indoor and outdoor units must be as short as possible and is in any case limited by compliance with the maximum height difference values between the units. Diminution of the difference in height between the units (H1,H2) and of the pipe lengths (L) will limit the load losses, consequently increasing the overall efficiency of the machine.

Comply with the limits given in the following tables.

Contact our technical department for the required modifications if the units must operate beyond the specifications given above.

TIGHTNESS CHECK (RECOMMENDED OPERATION)

Before setting the system in a vacuum, it is advisable to make sure that the cooling circuit is tight, including the connecting joints between the pipes and the indoor unit. Proceed in the following way:

• With the service valves of the outdoor unit completely shut, remove the cap from the service tap (1- side figure) of the gas connection (the larger one)

• Connect the service valve to a monometric unit plus nitrogen bottle (N2).

• Pressurize the system to a maximum 30 bar using the nitrogen in the bottle.

• Use liquid soap to check that the joints are tight.

Keep the bottle vertical during the pressurizing operation to prevent liquid nitrogen from infiltrating into the system!

• Check all the connection joints on both the outdoor and indoor units to make sure that they are tight. Bubbles will form if leaks are present. If bubbles appear, make sure that the unions have been tightened and that the flares are the right shape.

• Wipe off the liquid soap with a rag.

• Reduce the pressure of the nitrogen in the circuit by loosening the charge pipe from the bottle.

• Having reduced the pressure, disconnect the nitrogen bottle.

VACUUM OPERATION (OBLIGATORY)

Air and humidity in the cooling circuit impair the operation of the unit with effects such as:

• Increased pressure.

• Reduced efficiency.

• Formation of ice on the capillary and subsequent blockage of the same.

• Corrosion in the circuit.

This is why a vacuum must be created in the connection pipes and indoor unit. Proceed in the following way:

• Connect the previously described charging pipe to the vacuum pump.

• Turn on the relative knob on the monometric unit to allow the pump to access the cooling circuit.

• Wait until the pressure level measured by the pressure gauge is around 3 mm Hg (400 Pa)

• As soon as the required vacuum value is reached, shut the connection cock and stop the vacuum pump.

■ To activate the system it is necessary to open both the liquid and gas shut-off valves of the outdoor unit: remove the caps from both

valves, and then open the valves with an Allen wrench.

■ It is advisable to open the valves when the installation of the system is complete from an electric and hydraulic point of view and it

is therefore possible to proceed with the ﬁ rst start-up.

The safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto the ﬂ oor in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and ﬂ oods the room, the boiler manufacturer cannot be held liable.

Before installation, ﬂ ush all the pipes of the system thoroughly to remove any residuals or impurities that could affect proper operation of the unit. For that purpose only use suitable guaranteed products for heating systems (see next section), that do not harm metals, plastics or rubber. The manufacturer declines any liability for damage caused to the generator by failure to properly clean the system.

AVVERTIMENTO

Tips for a successful installation

For a correct design and installation of the hydraulic plant comply the local laws governing safety matters and sound. The following information is suggestion for a correct installation of the unit:

• Before connecting the unit to the system wash adequately the pipes using clean water, filling and emptying and cleaning the filters.

Only after that proceed connecting the unit to the system; this operation is crucial to ensure proper start-up without the need to have repeated stops to clean the filter, with the possible risk of damage to heat exchangers and other components.

• Check by qualified personnel the quality of the water or of the mixture used; avoid the presence of inorganic salts, biological load

(seaweeds, etc.) suspended solids, dissolved oxygen and the pH. Water with inadequate characteristics can cause a pressure drop increase due to a rapid fouling of the filter, energy efficiency decrease and corrosive symptom increase that can damage the unit.

• The pipes must have the least possible number of bends to minimize load losses and must be adequately supported in order to

prevent the connections of the unait from being excessively stressed.

• Install on-off valves near components that need to be serviced to isolate them when maintenance work needs to be done and to

allow them to be replaced without having to discharge the system.

• Before isolating the pipes and charging the system, carry out preliminary inspections to make sure that there are no leaks.

• Isolate all the chilled water pipes to prevent condensation from forming along the pipes themselves. Make sure that the material

used is the steam barrier type, failing this, cover the insulation with an appropriate protection. Also make sure that the air venting valves can be accessed through the insulation.

• The circuit can be maintained under pressure using an expansion vessel (present in the unit) and a pressure reducer. A system filling

device can be used that automatically, under a pressure value, provides for the loading and maintenance of the desired pressure.

• Check that all plant components are able to withstand the maximum static pressure (depending on the height of the building to be

served).

To avoid corrosion problems in water exchangers make sure that the water used in the plant meets the requirements listed in the table.

It is mandatory to install at the inlet of the unit the Y-shape water filter (supplied with the unit).

Water pipework

Requirements

For temperature probes (eg T5 or T1b) the maximum permitted cable length is 20m. This is the maximum allowed distance between the domestic hot water tank and the unit (only for installations with a domestic hot water tank). To optimize efficiency, we recommend installing the domestic hot water tank as close as possible to the unit

■ If the installation is equipped with a domestic hot water tank (optional), please refer to the domestic hot water tank Installation & Owner's Manual.

■ If there is no glycol in the system (antifreeze) or if the unit is not able to remain electrically powered for possible blackouts, in order to avoid possible icing problems, empty the water during winter.

NOTE

INSTALLATION

■ Be careful not to deform the unit’s piping by using excessive force when connecting the piping. Deforming the piping can cause the unit to malfunction.

■ The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the

water piping.

■ Water connections must be made in accordance with the outlook diagram delivered with the unit, with respect to the water intake

and water outlet (refer to section "DIMENSIONAL AND PHYSICAL DATA"). If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting

the water circuit:

■ Use clean pipes only.

■ Hold the pipe end downwards when removing burrs

■ Cover the pipe end when inserting it through a wall so that no dust and dirt enter.

■ Use a good thread sealant for sealing the connections. The sealing must be able to withstand the pressures and temperatures of

the system.

■ When using non-brass metallic piping,make sure to insulate both materials from each other to prevent galvanic corrosion. Never

use Zn-coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the unit's internal water circuit.

Protecting the water circuit against freezing

Frost can cause damage to the hydraulic circuit. If the unit's hydraulic circuit is expected to be subject to temperatures that may cause freezing, care must be taken to prevent freezing of the system.

All hydraulic parts are insulated to reduce heat loss. Insulation must be present on the ﬁ eld piping. The unit is already equipped with several features to prevent freezing.

■ The software contains special functions using the heat pump to protect the entire system against freezing. When the temperature of the water ﬂ ow in the system drops to a certain value, the software will heat the water, either using the heat

pump, the electric heating tap, or the backup heater(if backup heater box is installed). The freeze protection function will turn off only when the temperature increases to a certain value.

In case of a power failure, the features mentioned above cannot protect the unit from freezing. Since a power failure could happen when the unit is unattended, the supplier recommends adding glycol to the water system. Refer to “Caution: Use of glycol”.

Since a power failure could happen when the unit is unattended, the supplier recommends adding glycol to the water system. Refer to “Caution: Use of glycol”.

Depending on the expected lowest outdoor temperature, make sure the water system is ﬁ lled with a concentration of glycol as mentioned in the table below.

When glycol is added to the system, the performance of the unit will be affected. The correction factor of the unit capacity, ﬂ ow rate and pressure drop of the system is listed in the table below:

INSTALLATION

ETHYLENE GLYCOL IS TOXIC

Use of glycol

■ Glycol use for installations with a domestic hot water tank:

- Only propylene glycol having a toxicity rating or class of 1, as listed in "Clinical Toxicology of Commercial Products, 5th edition" may be used.

■ If there is too much pressure when using glycol, connect the safety valve to a drain pan to recover the glycol.

■ Uninhibited glycol will turn acidic under the inﬂ uence of oxygen. This process is accelerated by presence of copper and at

higher temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system.

It is of extreme importance:

■ That the water treatment is correctly executed by a qualiﬁ ed water specialist.

■ That a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols.

■ That in case of an installation with a domestic hot water tank, only the use of propylene glycol is allowed. In other installations

the use of ethylene glycol is ﬁ ne.

■ That no automotive glycol is used because their corrosion inhibitors have a limited lifetime and contain silicates that can foul or plug the system;

■ That galvanized piping is not used in glycol systems since it may lead to the precipitation of certain elements in the glycol’s corrosion inhibitor;

■ To ensure that the glycol is compatible with the materials used in the system.

■ Be aware of the hygroscopic property of glycol. It absorbs moisture from the environment.

■ Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concentration is then lower

and the water could freeze.

■ Preventive actions must be taken to ensure minimal exposure of the glycol to air.

WARNING

CAUTION

During ﬁ lling, it might not be possible to remove all air in the system. Remaining air will be removed through the automatic air purge valves during the ﬁ rst operating hours of the system. Topping up the water afterwards might be required.

■ The water pressure indicated on the manometer will vary depending on the water temperature (higher pressure at higher water temperature). However, at all times water pressure should remain above 0.3 bar to avoid air entering the circuit.

1. Connect the water supply to the ﬁ ll valve and open the valve.

2. Make sure the automatic air purge valve is open (at least 2 turns).

3. Fill with water until the manometer indicates a pressure of approximately 2.0 bar. Remove air in the circuit as much as possi-

ble using the air purge valves. Air present in the water circuit might cause malfunctioning of the backup heater.

NOTE

Filling with water

Piping insulation

The complete hydraulic circuit that includes all the pipes must be insulated to avoid heat loss, condensation during operation, reduction of heating or cooling capacity, as well as to prevent freezing of water pipes during winter.

INSTALLATION

■ Wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions given in this paragraph.

■ All wiring and electrical components must be installed by a qualiﬁ ed electrician.

■ Provide a main switch or other disconnection devices in the system in accordance with local laws and regulations.

■ Use a dedicated power line.

■ Install fuses (or circuit breakers) and power cables that match the maximum electrical current of the unit.

■ Install a differential switch according to local laws and regulations. Failure to install a differential switch can result in electric shock

and ﬁ re.

■ Install a differential switch with the following characteristics:

- intervention value equal to 30 mA

- trip time less than 0.1 s

■ Make sure all electrical connections are carried out properly. Use the speciﬁ ed cables and ensure that the terminal connections and cables are protected from water and other external forces to avoid the risk of ﬁ re.

■ Accommodate the power supply and control cables so that the front panel can be mounted correctly and therefore do not force the cables themselves to avoid the risk of ﬁ re or electric shock.

■ Do not compress the cables and make sure that they do not come into contact with the pipes and sharp edges. Ensure that no external pressure is applied to the cables.

BEFORE ANY OPERATION WHICH REQUIRES REMOVING THE COVER, DISCONNECT THE UNIT FROM THE POWER SUPPLY THROUGH THE MAIN SWITCH.

DO NOT TOUCH THE ELECTRICAL COMPONENTS IN ANY CASE WITH THE CLOSED MAIN SWITCH! THERE IS THE RISK OF ELECTRIC SHOCK WITH RISK OF INJURY OR DEATH!

The appliance must be connected to an effective earthing system, as provided for by the current safety regulations. Have the efﬁ ciency and suitability of the earthing system checked by professionally qualiﬁ ed personnel, the manufacturer is not responsible for any damage caused by lack of earthing of the system.

CAUTION

Electrical conections indoor unit

1. Opening the front panel

Some components inside the boiler can reach high temperatures that could cause serious problems burns. Before carrying out any operation, wait for these components to cool or alternatively wear suitable gloves.

To dismount the front panel of the indoor unit:

- Partially unscrew the screws A (see figure to the side).

- Pull the panel B out and release it from the upper fixings.

2. Make the connections referring to the functional electrical diagram present in this manual.

3. Proceed in reverse order to reassemble the front panel. Make sure that it is correctly attached to the upper fixing and completely resting on the side panels. The head of the screw "A", once tightened, must not be underneath the lower bending stop (see figure at the side).

INSTALLATION

■ The unit is equipped with an inverter. Installing a power factor correction not only reduces the effect of power factor improvement, but can also cause an abnormal heating of the condenser due to high frequency waves. Never install a power factor device as it may cause damage to the unit.

☞

■ A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the ﬁ xed wiring in accordance with relevant local laws and regulations.

■ Switch off the power supply before making any connections.

■ Never squeeze bundled cables and make sure they do not come in contact with the piping and sharp edges. Make sure no exter-

nal pressure is applied to the terminal connections.

■ All ﬁ eld wiring and components must be installed by a licensed electrician and must comply with relevant local laws and regulations.

■ The ﬁ eld wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions

given below.

■ Be sure to use a dedicated power supply. Never use a power supply shared by another appliance.

■ Be sure to establish a ground. Do not ground the unit to a utility pipe, surge protector, or telephone ground.

Incomplete grounding may cause electrical shock.

■ Be sure to install a ground fault circuit interrupter (30 mA). Failure to do so may cause electrical shock.

■ Be sure to install the required fuses or circuit breakers.

WARNING

■ Be sure to install a differential switch with the following characteristics:

- intervention value equal to 30 mA

- trip time less than 0.1 s

- that it is compatible with the inverter (resistant to high frequency electromagnetic disturbances) in order to avoid unnecessary interventions
