3 Description
3.1 General description
The ALEZIO V220 heat pump comprises:
4 A reversible outside module for energy production in hot or cold
mode.
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 inside module handles domestic hot water production.
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 The steel tank is lined with food quality standard enamel vitrified
at 850°C, which protects the tank from corrosion.
4 The coil-shaped heat exchanger welded into the tank is made of
smooth piping, its external surface, which comes into contact with
drinking water, being enamelled.
4 The appliance is insulated by CFC-free polyurethane foam, which
reduces heat losses to a minimum.
4 The outside casing is made of painted steel sheeting.
4 The tank is protected against corrosion by a magnesium anode.

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:
1. Go to the Installer menu
