The ALEZIO EVOLUTION heat pump comprises:
An outdoor unit for energy production in heating mode only when it is
combined with an uninsulated indoor module.
A reversible outdoor unit for energy production in heating or cooling
mode when it is combined with an insulated indoor module.
An indoor module with a control panel to handle the heat exchange be­
tween the R410A fluid and the hydraulic circuit.
Both units are connected by means of refrigeration and electrical connec­
tions.
The system offers the following advantages:
The heating circuit is housed in the insulated volume within the home.
Thanks to the DC inverter system, 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.

4.2.1 Circulation pump

Note
The benchmark for the most efficient circulators is EEI ≤ 0.20.

4.2.2 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 en­
ergy consumption. Both hybrid operating modes are available via the pa­
rameter .
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 cheap­
est generator according to the coefficient of performance of the heat
pump and according to energy cost.
