3 Description

3.1 General description

The ALEZIO heat pump comprises:

4 An outside module for energy production in hot mode only when

it is combined with an uninsulated inside module.

4 A reversible outside module for energy production in hot or cold

mode when it is combined with an insulated inside module

4 An inside module with a control panel to handle the thermal

exchange between the R410A fluid and the hydraulic circuit

The two units are connected by means of refrigeration and electrical

connections.

The system offers the following advantages:

4 The heating circuit is housed in the insulated volume within the

home. There is no danger of the pipes freezing.

4 Thanks to the DC inverter system, the heat pump modulates its

output to adapt to the needs of the home.

4 The control panel uses the outside temperature sensor to adjust

the temperature of the heating circuit according to the outside

temperature.

4.3.5. Hybrid operating mode

CAUTION

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 parameter U1. 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.

To access the parameters:

Press the

key 3 times.

The symbol

flashes.

Press the key

to enter the "Installer" menu.

3. Use the + and - keys to switch from one parameter to another.
