2.4 Operating principle

The equipment belonging to the 1.9 kW and 2.9 kW series is capable of producing domestic hot water mainly by using heat pump technology. A heat pump is capable of transferring thermal energy from a low temperature source to another with a higher temperature and vice versa (heat exchangers).

The equipment uses a water circuit consisting of a compressor, an evaporator, a condenser and a lamination valve; a liquid/gas coolant flows inside this circuit (see paragraph 4.6).

The compressor creates a difference in pressure inside the circuit that allows a thermodynamic cycle to be obtained: this sucks the coolant fluid in through an evaporator, where the fluid itself evaporates at a low pressure by absorbing heat, it is compressed and driven towards the condenser where the fluid condenses at a high pressure releasing the absorbed heat. After the condenser, the fluid passes through the so-called "lamination valve" and by losing pressure and the temperature starts to vaporise, it re-enters the evaporator and the cycle starts all over again.

Fig. 1 – Operating principle

The operating principle of the equipment is as follows (Fig. 1):

I-II: The coolant fluid sucked in by the compressor flows inside the evaporator and while it evaporates, it absorbs the "ecological" heat given by the air.

At the same time, the ambient air is sucked in by the equipment by a fan; the air loses it heat by passing over the finned-tube battery of the evaporator;

II-III: The coolant gas passes inside the compressor and it under goes an increase in pressure that causes a rise in temperature; transforming this into superheated steam;

III-IV: Inside the condenser, the coolant gas releases its heat to the water inside the tank (boiler). This exchange process makes it possible for the coolant to pass from superheated steam to a liquid state by condensing at a constant pressure and undergoing a reduction in temperature;

IV-I: The liquid coolant passes through the lamination valve, it undergoes a sudden drop in both pressure and temperature and it partially vaporises bringing pressure and temperature back to the initial conditions. The thermodynamic cycle can begin.

2.5 Available versions and configurations

The heat pump is available, in relation to the thermal power (1.9 kW version), which can be set up in different configurations, depending on the possible integrations with other heating sources (e.g. solar thermal, biomass power, etc.).

Fig. 3b – Example of dual duct connection

Carry out the installation of each air duct taking care that:

- The weight of such does not adversely affect the equipment itself;

- Maintenance operations can be carried out;

- This is adequately protected so as to avoid the accidental intrusion of material inside the equipment itself;

- It doesn't exceed the maximum suggested length of 6 meters (with 2 elbow junctions 90^ ).

- The maximum total allowable pressure drop for all components, including through holes for mounting on external wall, within the pipe system does not exceed 120 Pa.

During operation, the heat pump tends to lower the ambient temperature if the external air duct is not carried out.

An appropriate protection grid must be installed in line with the discharge pipe conveying air to the outside with the aim of avoiding foreign bodies from entering the equipment. In order to guarantee maximum device performance, the grid chosen must ensure low pressure loss.

In order to avoid the formation of condensate: insulate the air discharge pipes and the air duct cover connections with steam-tight thermal cladding of an adequate thickness.

If it is considered necessary in order to prevent flow noise, sound mufflers can be mounted.

Fit the pipes, the wall through holes and the connections to the heat pump with vibration damping systems.

WARNING!

The simultaneous operation of an open-flue firebox (e.g. an open-flue fireplace) together with the heat pump causes a dangerous environmental pressure drop. This could cause the backflow of exhaust gas into the environment itself.

Do not operate the heat pump together with an open-flue firebox.

Use only sealed-chamber fireboxes (approved) with a separate duct for combustion air.

Keep the doors to the boiler room closed and hermetically sealed if it does not have a combustion air supply in common with inhabited areas.

6.2.1 Particular installation conditions

One of the peculiarities of the heat pump heating system is represented by the fact that these units cause a considerable reduction of the air temperature that is generally ejected from inside the home. Apart from being colder than the ambient air, the exhaust air is also completely dehumidified; for this reason, it is possible to allow the air to flow back into the home in order to cool specific environments or rooms during the summer. Installation consists of the splitting of the discharge pipe to which two shutters are applied ("A" and "B") with the aim of directing the air flow either towards the inside (Fig. 5a) or the outside of the home (Fig. 5b).

6.3 Device mounting and connection

The device must be installed on a stable, flat floor surface that is not subject to vibration.

N.B.

It is compulsory to install a dirt filter on the cold water inlet pipe. The equipment should not work with water hardness lower than 12°F; on the contrary, when the water hardness is particularly high (higher than 25°F), it is recommended to use a water softener, properly calibrated and monitored; in this case the residual hardness should not fall below 15°F.

PLEASE NOTE!

It is advisable for the system installer to install a 7-bar safety valve on the cold water intake pipe (Fig. 8a).

N.B.

The safety equipment for protection against over pressure must be operated regularly in order to remove limescale deposits and to check that it is not blocked (Fig. 8a)

N.B.

For a proper installation of the equipment, a hydraulic safety group in accordance to UNI EN 1487:2002 standard should be provided. It should include at least: a shut-off valve, a check valve, a control device of the check valve, a safety valve, a device to interrupt the water load (Fig. 8a)

N.B.

The drain hose connected to the equipment for overpressure protection must be installed with a continuous downward slope (slope>3°) and in an area protected against the formation of ice (Fig. 8)

WARNING!

In case an expansion vessel is not being installed, make sure that in the cold water intake there is not any non-return valve installed.

WARNING!

The heat pump for the production of domestic hot water is capable of heating water up to more than 60°C. For this reason, as a protection against burns, it is necessary to install an automatic thermostat mixing equipment to the hot water pipe (Fig. 8).

6.4.1 Condense drain connections

Condensate that forms during the operation of the heat pump flows through an appropriate discharge pipe (G 1/2") that passes inside cladding and it comes out on the side of the equipment.

This must be connected to a duct via a siphon so that the condensate can flow freely (Fig. 9a or Fig. 9b).

6.6 Electrical connections

The appliance is supplied with a power supply cable (should the latter need to be replaced, use only original spare parts supplied by the manufacturer or its service agent). It is powered through a flexible cable and a socket/plug combination (Fig. 11 and Fig. 12). An earthed Schuko socket with separate protection is needed for the connection to the mains power supply.

It is advisable to carry out a check on the electrical system to verify conformity to the regulation in force.

Verify that the electrical system can suitably withstand the water heater's maximum power consumption values (refer to data plate), in terms of the size of the cables and their conformity to the regulation in force. It is forbidden to use multiple outlet sockets, extension cable or adaptor. The earth connection of the appliance is required. It is forbidden to use piping from the water, heating and gas systems for earthing the appliance Prior to operating the machine, make sure that the electricity mains voltage conforms to the value indicated on the appliance's data plate.

The manufacturer of the appliance shall not be held liable for any damage caused by failure to earth the system or due to anomalies in the electric power supply. To disconnect the appliance from the mains, use a bipolar swith complying with all applicable CEI-EN regulations in force (minimum distance between contacts 3 mm, switch preferably equipped with fuse). The appliance must comply with European and national standards, and must be protect by a 30 mA differential switch.

6.6.1 Remote links

The equipment is designed to be connected to other remote energy systems (photovoltaic and solar thermal power systems).

The user interface has two digital inputs with the following functions:

x

Digital 1: Input from the solar thermal power system. When a free contact is established between terminals 30 and 31 (cable: brown/yellow) and the water temperature measured by lower probe is higher than SP8, the heat pump stops and water is heated up by the solar panels; the heat pump starts again when the contact is released

and time set by C13 is passed or immediately if the lower probe temperature is lower than SP8.

x

Digital 2: Input from photovoltaic system. When a free contact is established between terminals 31 and 32 (cable: green/white) and the heat pump reaches the SP5 temperature (default setting 62°C), the hot water nominal temperature is raised by 7°C. It is possible to change the SP6 parameter (e.g.: raising the temperature from 62°C to 70°C) so that, if there is enough PV electrical energy, the heat drop from 62°C to 70°C is made by the immersion electric heating element (if SP6 is the same as SP5, the electric heating element will never activate).

6.6.1.1 Remote link mode

As regards links to digital inputs, the equipment is provided with an additional 4-core cable that has already been linked to circuit board of the user interface (placed inside the equipment Fig. 14). The remote links to any energy systems must be carried out by a qualified installer (junction boxes, terminals and connection cables).

The following illustrations show an example of a remote link (Fig. 13 and Fig. 13a).

Fig. 13 – Example of a remote link

Digital input 1 Digital input 2 30 31 31 32 Fig. 13a - Detailed example of a remote link

To access the 4-core cable for remote connection it is necessary to remove the upper cover of the boiler (see paragraph 9.1 Fig. 18), and take the cable outside through the dedicated opening, that is already present on the back cover, as indicated in Fig. 14.

8.1.2 Operating logic

8.1.2.1 Operating modes

The equipment foresees the following operating modes:

• AUTOMATIC operating mode:

This mode mainly uses the renewable energy of the heat pump as a support measure, the electric heating elements can be enabled; these latter heating sources are enabled if the water temperature is below a certain level, or in the event that a temperature exceeding SP5 parameter is required;

• ECONOMY operating mode:

This mode uses only the renewable energy of the heat pump without ever enabling the electric heating elements. It takes longer to enable but it has considerable energy saving characteristics;

• OVERBOOST operating mode:

This mode makes it possible to heat water rapidly by using both the heat pump and the electric heating elements. This function can be manually enabled when the temperature of the water inside the storage tank is lower than SP3 parameter. At the end of the heating process, the function is automatically disabled and the equipment is automatically restored to the Automatic or Economy mode depending on which of these functions was previously set by the user;

• ANTI-LEGIONELLA operating mode

This function is used as an anti-bacterial treatment by increasing the temperature of the water to 60^ C. This function is periodically and, in any case, automatically enabled every 30 days, regardless of the operating mode enabled;

• DEFROSTING mode

This function is necessary in order to eliminate the frost deposits that form and which prevent heat transmission. This function is automatically enabled when the equipment is operated at low environmental temperatures.

When the equipment is switched on for the first time, it is pre-set in the ECO (Economy) mode with a water set point of 55^ C with the aim of guaranteeing the best possible energy saving function with the support of only renewable energy sources. Please note that the use of such function guarantees the user an average energy saving of approx. 70% when compared to a normal electric boiler.

Pr3	Error in evaporator probe
	Solutions:- The same as the previous situation but relating to the evaporator probe.- The equipment stops working.

When the cause of the alarm has been removed, the normal operation of the equipment is restored.

8.1.3.13 Defrosting

Defrosting can be enabled in the following way:

- Automatically, when the temperature of the evaporator is below that established in parameter d17 (only if P4 has a value other than 0);

In any case, between one defrosting procedure and another, the compressor must have been left switched on for a period either longer than or equal to d18 minutes. Otherwise the request to enable the defrosting procedure will not be accepted.

If P4 = 1, d2 represents the temperature of the evaporator, above which the defrosting procedure is terminated. Vice versa, if P4 = 0 or P4 = 2, parameter d2 is not taken into consideration.

If during the defrosting procedure the evaporate or probe is above the threshold set by means of parameters d2 and P4 = 1, the request to enable the defrosting procedure is not accepted.

The defrosting procedure consists of three stages:

• Defrosting stage: Parameter d3 establishes the maximum duration of the stage. Output status:
• The compressor is active if d1 = 1, otherwise it is switched off;

8.2 Particular operations

The product has a fan speed control system that increases the speed of the same, when the ambient temperature drops to below -1^ , at higher temperatures, the fan maintains a lower speed in order to reducing the noise of the equipment.

The equipment is also provided with a verification system of the environmental conditions concerning the temperatures of the external incoming air. The below described function is necessary to avoid the equipment working with the heat pump mode out of specification, which may cause faults to the compressor and the consequent interruption of the functionality.

By every start, the fan is activated for a time set up by parameter C12 corresponding to 1 minute. After this time, the system measures the incoming air temperature. If the temperature is equal to or lower than parameter SP9 (-7°C), then the conditions for the activation of the heat pump unit are not met, therefore the electric resistance is activated. The heating-up process continues with the help of the electrical resistance until the set point established with the ongoing active cycle is reached.

The system verifies cyclically (every 120 minutes) the environmental conditions and activates the heat pump mode only when these conditions are adequate for its operation.

9 Maintenance and cleaning

WARNING!

Any equipment repair must be performed by qualified personnel. Improper repairs can put the user in serious danger. If your equipment needs to be repaired, please contact the technical assistance service.

WARNING!

Before attempting any maintenance operation, make sure that the equipment is not and cannot be accidentally connected to the power supply. Therefore, disconnect the equipment from the mains power supply before carrying out any maintenance or cleaning activities.

9.1 Resetting of safety equipment

The device is equipped with a safety thermostat. When manually reset, the equipment is tripped in case of over-heating.

In order to reset the protection it is necessary to:

• Disconnect the device from the mains power supply;
• Remove any air ducts (see paragraph 6.1.1);
• Remove the upper cover by undoing the appropriate locking screws (Fig. 18);
• Manually reset the tripped safety thermostat from the top (Fig. 19). In the event of the tripping, the central pin of the thermostat sticks out by approximately 4 mm;
• Reassemble the upper cover that was previously removed.

Diagram of a device with an inset showing a button labeled 'Click' (no text or symbols on the diagram itself)

Fig. 19 – Resetting the Safety thermostat

WARNING!

The tripping of the safety thermostat can be caused by a fault linked to the control board or by the absence of water inside the tank.

WARNING!

Carrying out repair operations on parts that perform safety functions jeopardises the safe operation of the equipment. Substitute the faulty elements only with original spare parts.

N.B.

The intervention of the thermostat excludes the operation of the electric heating elements but not the heat pump system within the permitted operating limits.

9.2 Quarterly inspections

• Visual inspection of the general conditions of the equipment systems as well as the absence of leaks;
  • Inspection of the ventilation filter (see paragraph 9.4).

9.3 Annual inspections

• Inspection of the tightness of bolts, nuts, flanges and water supply connections that may have been loosened by vibration;
• Check the state of integrity of the magnesium anodes (see paragraph 9.5).

9.4 Cleaning of the ventilation filter

In the upper part of the equipment there is a ventilation filter. This must be periodically cleaned in order to maintain the perfect efficiency of the system.

After every 1000 hours of operation, the display of the equipment shows the "FiL" alarm that indicates the need to check the cleanliness of the filter.

To remove the filter, it is necessary to grab it with the fingers from the dedicated side opening and pull it outside (Fig. 20).

The filter can be cleaned with rinsing, water gush or slamming. Since the filter is made of stainless steel, it does not need to be periodically substituted.

Side slot Ventilation filter

Fig. 20 – Details of the ventilation filter

N.B.

The filter obstruction reduces the heat pump system performance causing insufficient, or, even total lack of ventilation.

9.5 Magnesium anodes

The magnesium anode (Mg), also called "sacrificial" anode, avoids any parasitic currents that are generated inside the boiler that can trigger corrosion processes on the device surface.

In fact, magnesium is a metal with a lower electrochemical potential when compared to the material that lines the inside of the boiler, therefore it first attracts the negative charges that form with the heating of the water and that cause it to corrode. Therefore, the anode “sacrifices” itself by corroding instead of the tank. The boiler has two anodes, one that has been mounted in the lower part and another in the upper part of the tank (the area that is most subject to corrosion).

The integrity of the magnesium anodes must be checked at least every two years (even better if checked on an annual basis). The operation must be carried out by qualified personnel.

Before performing the inspection, it is necessary to:

• Close the cold water input supply;
  • Empty the water from the boiler (see paragraph 9.6);
• Unscrew the upper anode and check its state of corrosion, if more than 30% of the anode surface is corroded then it is necessary to replace it;
• Carry out the same operation for the lower anode.
• The anodes have appropriate sealing gaskets, in order to avoid causing water leaks, it is recommended to use anaerobic sealant for threads compatible for use on sanitary and heating systems. The gaskets must be substituted both in case of inspection as well as the replacement of anodes with new gaskets.

9.6 Emptying the boiler

It is advisable to drain the water from the boiler if the boiler is not in use for a certain period of time, especially in low temperatures.

It is recommended to drain the water from the boiler if the boiler remains stationary for a certain period of time, especially at low temperatures.

Before draining the water, the appliance must be switched off and disconnected from the mains. Proceed as follows to drain the water from the boiler: switch off the appliance and disconnect the power supply cable from the mains, close the water shut-off valve (see 2 fig. 8 paragraph 6.4), operate the drain tap (see 5 fig. 8 paragraph 6.4). To facilitate the flow of water to the drain it is recommended (if it is not already present), to install a hose connector on the drain tap.

N.B.

It is important to empty the system in case of low temperatures in order to avoid the water freezing.

9.7 Inspection of the electrical resistance compartment

In case of access to the resistance compartment, refit the cover with the arrow pointing upwards

Fig. 21 – Refit the cover
