4 Description of the product
4.1 General description
The hybrid heat pump comprises:
an indoor module for the production of heating circuit water a reversible outdoor unit for the production of energy in heating mode and in cooling mode.
The indoor module comprises:
a hydraulic module, which groups together the functions for the heat pump's indoor module a wall-mounted condensing gas boiler, installed on the front of the hy draulic module
The indoor module and the outdoor unit are connected by means of refrig erant and electrical connections.
The system offers the following advantages:
An extremely compact solution which can be easily integrated into the most confined areas of any residence. The heating circuit is housed in the insulated volume within the home. Thanks to the DC inverter system, the hybrid heat pump modulates its output to adapt to the needs of the residence. The control system uses the outside sensor to adjust the temperature of the heating circuit according to the outside temperature. The outer casing of the hydraulic module is made of painted steel sheet ing.
4.2 Operating principle
Heat pumps in the Alezio G hybrid range extract heat from the air and re turn it to the heating circuit via the refrigerant. The efficiency of a heat pump is expressed in the form of a coefficient of performance (COP), de fined as the ratio between the heat provided and the power consumed.
The heat pump comprises an evaporator, a compressor, a condenser and an expansion valve. The indoor module includes the condenser. The other components (evaporator, compressor and expansion valve) are located in the outdoor unit.
1. The refrigerant fluid in this circuit is converted from the liquid state to the gaseous state in the evaporator, making it possible to recover heat from the air.
2. The compressor increases the fluid pressure, which thus increases the temperature.
3. In the condenser, the fluid transfers the heat to the heating circuit while converting to the liquid state.
4. The refrigerant passes through the thermostatic expansion valve and returns to the initial state at low pressure and low temperature before returning to the evaporator.

7.2.1 Checking the water pressure
1. Check the water pressure. The water pressure must be at least 0.8 bar.
2. If the water pressure is lower than 0.8 bar, top up the central heating system.
7.3
Cleaning the casing
1. Clean the outside of the appliance using a damp cloth and a mild detergent.
7.4
Venting the system
Any air in the boiler, the pipes or the valves must be removed in order to prevent unwanted noises that may occur during heating or when tapping water. Proceed as follows:
1. Open the valves of all the radiators connected to the system.
2. Set the room thermostat to the highest possible temperature.
3. Wait until the radiators are warm.
4. Ensure that the boiler is disconnected from the power supply.
5. Wait approximately ten minutes, until the radiators feel cold.
6. Vent the radiators. Work from the lowest to the highest.
7. Open the venting valve with the bleed key, keeping a cloth pressed against the vent.
Warning The water may still be hot.
8. Wait until water comes out of the venting valve and then close the venting valve.
9. Turn the boiler on. A four-minute venting cycle is performed automatically.
10. After venting, check that the water pressure in the system is still ad equate. If necessary, top up the central heating system.
11. Adjust the room thermostat or temperature control.

8.1 Error codes
8.1.1 Error codes on the PCB EHC-02
An A.xx.xx or H.xx.xx error code corresponds to a temporary status of the hybrid heat pump after a fault is detected. If an error code remains after several automatic start-up attempts, the hybrid heat pump switches to fail ure mode. Failure mode is indicated by a E.xx.xx type fault code. The hy brid heat pump only restarts once the fault is resolved.
Note An error code is linked to a PCB. If an error code is displayed, check which PCB is affected.

11.1 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.
