4 Description of the product

4.1 General description

The ALEZIO V220 EVOLUTION heat pump is composed of:

A reversible outside module for energy production in Hot or Cold mode. An inside module with a control panel to handle the thermal exchange between the R410A fluid and the hydraulic circuit.

Both units are connected by means of refrigeration and electrical connections. The inside module handles domestic hot water production.

The system offers the following advantages:

The heating circuit is housed in the insulated volume within the home. Thanks to the DC inverter, the heat pump modulates its output to adapt to the needs of the home. The control panel uses the outside sensor to adjust the temperature of the heating circuit according to the outside temperature. The steel domestic hot water tank is lined with food quality standard enamel vitrified at 850°C, which protects the tank from corrosion. The heat exchanger in the domestic hot water tank is a coil welded inside the tank, made of smooth piping. Its external surface, which comes into contact with drinking water, is enamelled. The appliance is insulated by Chlorofluorocarbon-free polyurethane foam, which helps to reduce heat losses to a minimum. The outside casing is made of painted steel sheeting. The tank is protected against corrosion by a magnesium anode.

4.2 Operating principle

4.2.1 Hybrid operating mode

Note The hybrid operating mode is only available for appliances with hydraulic back-up.

The appliance offers a choice between several hybrid operating modes. The modes available offer either optimised energy consumption according to energy cost, or optimised energy consumption according to primary energy consumption. Both hybrid operating modes are available via the parameter .

In optimised primary energy consumption mode, the control system chooses the generator that consumes the least primary energy. In optimised energy cost mode, the control system chooses the cheapest generator according to the coefficient of performance of the heat pump and according to energy cost.

7 Maintenance

7.1 General instructions

Maintenance operations are important for the following reasons:

To guarantee optimum performance. To extend the life of the equipment. To provide an installation which offers the customer optimum comfort over time.

Caution An annual service of the heat pump is mandatory.

7.2 Maintenance instructions

1. Check the hydraulic pressure in the installation.

Note If the water pressure is lower than 1 bar, more water should be added. If necessary, top up the water level in the heating system (recommended hydraulic pressure between 1.5 and 2.0 bar, or between 0.15 and 0.2 MPa)..

See Top up the installation with water, page 22.

2. Carry out a visual check for any water leaks.

3. Open and close the radiator valves several times a year. This helps to prevent the valves from seizing up.

4. Clean the outside of the heat pump using a damp cloth and a mild detergent.

Caution Only qualified professionals are permitted to clean the inside of the heat pump.

7.3 Top up the installation with water

If necessary, top up the water level in the heating system (recommended hydraulic pressure between 1.5 and 2 bar (0.15 and 0.2 MPa)).

1. Open the valves on all radiators connected to the heating system.

2. Set the room thermostat to as low a temperature as possible.

3. Put the heat pump in shut-down/frost protection mode.

See User settings, page 17.

4. Open the fill valve.

5. Close the fill valve when the pressure gauge shows a pressure of

1.5 bar (0.15 MPa).

6. Put the heat pump in heating mode.

See User settings, page 17.

7. When the pump has stopped, vent again and top up the water pressure.

Page 23

Note Filling and venting the installation twice a year should be sufficient to obtain an adequate hydraulic pressure. If it is often necessary to top up the installation with water, contact your installer.

7.4 Venting the heating system

It is essential that you vent any air in the domestic hot water tank, the pipes and the taps to prevent the annoying noises likely to be produced during heating or when drawing off water.

7.4.1 Manual venting

1. Open the valves on all radiators connected to the heating system.

2. Put the heat pump in shut-down/frost protection mode.

3. Vent the underfloor heating circuits and the radiators. First vent the lower floors A and then the upper floors B.

Note The heating pump stops 5 minutes after selection of the shutdown/frost protection mode. If the outside temperature is lower than 3°C, the heating pump continues to run.

7.4.2 Automatic venting

If the parameter is set to 0, the heat pump runs an automatic venting cycle when it is switched on. If the parameter is set to 1, a domestic hot water tank is connected. Automatic venting starts up only if the measured domestic hot water

temperature is lower than 25°C. Automatic venting takes approximately one minute. It is possible to manually extend automatic venting to more than one minute.

1. When powering up, the word flashes. Press the A and B keys ( ) simultaneously. An automatic venting cycle begins. The word

stops flashing.

2. Press the A and B keys ( ) simultaneously to stop the venting cycle.

Caution After venting, check whether the pressure in the installation is still sufficient. Add more water to the installation if necessary.

10 Environmental

10.1 Energy savings

Tips on saving energy:

Do not block ventilation outlets. Do not cover the radiators. Do not hang curtains in front of the radiators. Install reflective panels behind the radiators to prevent heat losses. Insulate the pipes in rooms that are not heated (cellars and lofts). Turn off the radiators in rooms not being used. Do not run hot (or cold) water pointlessly. Install a water-saving shower head to save up to 40% energy. Take showers rather than baths. A bath consumes twice as much water and energy.

10.2 Room thermostat and settings

Various models of room thermostat are available. The type of thermostat used and the parameter selected impact total energy consumption.

A modulating regulator, which may be combined with thermostatic valves, is eco-friendly in terms of energy and offers an excellent level of comfort. This combination allows you to set the temperature separately for each room. However, do not install thermostatic radiator valves in the room in which the room thermostat is located. Complete opening and closing of the thermostatic radiator valves causes undesirable variations in temperature. Therefore, these must be opened/closed progressively. Set the room thermostat to a temperature of approximately 20°C to reduce heating costs and energy consumption. Lower the thermostat setting to approximately 16°C at night or when you are not at home. This reduces heating costs and energy consumption. Lower the thermostat setting well before airing the rooms. Set the water temperature to a lower level in summer than in winter (e.g. 60°C and 80°C respectively) when an ON/OFF thermostat is used. When clock thermostats and programmable thermostats are to be set, do not forget to take any holidays and days when no one is at home into account.
