Increase in temperature of the tank (without drawing) Domestic hot water temperature (with open tab).
• Regulation functions
- The initial temperature of the heating circuit is
controlled by water logic.
- In function of an initial heating temperature, the power
of the outdoor unit is modulated via the "inverter"
compressor.
- Management of the supplementary heating.
- The daily timer programme allows comfort or reduced
ambient temperature periods.
- Switching between summer/winter operation is
automatic
- Ambient sensor*: The ambient sensor provides a
corrective action to the water logic.
- Management of a 2nd heating circuit*.
- Domestic hot water: Hourly heating programme,
management of the comfort temperature and the
reduced temperature.
*When the heat pump is equipped with options and associated kits.
• Protection functions
- Anti-legionella cycle for the domestic hot water.
- Tank anti-corrosion protection by titanium anode (ACI).
- Antifreeze protection for the installation, DHW, etc.
• Hydraulic pressure monitoring
A pressure switch monitors the hydraulic pressure.

• Operating principle of the domestic hot water
(DHW)
DHW production takes priority over heating.
Two domestic hot water (DHW) temperatures may
be set: comfort temperature (line 1610 at 55 °C)
and reduced temperature (line 1612 at 40 °C).
The default DHW programme follows the hourly heating
programme with 1 hour's advance on start-up.
Depending on the parameter setting (1620), the comfort
temperature may be reached 24 hours / day or according
to the DHW programme
The reduced temperature value may be useful to avoid
restarting the DHW too many times and for too long
through the day.
The production of domestic hot water (DHW) is started
when the temperature in the tank is 7°C below (setting
of line 5024) the reference value temperature.
The domestic hot water (DHW) is produced by the heat
pump and the boiler top-up.
A switching function of "reduced" to "comfort" is
available on the front panel of the user interface
(see item 1 , figure 54, page 52 ).
Anti-legionnella cycles may be programmed.
• Fan coil units with integrated regulation
Do not use an ambient sensor in the zone concerned.
