If the room temperature is outside the heat pump's operating range, it will
cease the function. The water heater automatically activates the immer­
sion heater and the LA icon on the control panel will come on.
The room temperature range adapted for this operating mode is between
+3°C and +43°C.
For the 3 operating modes
the thermodynamic water heater can heat the domestic hot water to a
maximum temperature of 65°C,
the domestic hot water temperature set point can be set to between 25
and 70°C.

Operation in ECONOMY MODE

The thermodynamic water heater can heat the water using the following
sources of energy:
the heat pump,
the immersion heater
or both systems simultaneously.
Tab.23
T = Room temperature
At least one of the following 3 con­
ditions must be true:
T < +3°C
Water temperature > 65°C
T > +43°C
+3°C < T < Td
The following 2 conditions must be
true:
T > Td
Water temperature < 65°C

Operation in HYBRID MODE

Note
HYBRID MODE : heat pump with compulsory coupling to an in­
stant boiler.
The thermodynamic water heater can heat the water using 2 sources of
energy: heat pump or instant boiler:
the heat pump is intended to preheat the domestic hot water,
the instant boiler is used to provide heating of the domestic hot water
until the required temperature for use is obtained.
No electrical back-up for this mode.
Tab.24
T = Room temperature
T < T4
T4 < T < 43°C
Water temperature < 65°C
Operation in OPT.BACKUP (PEAK RATE/OFF-PEAK RATE
OPTIMISATION MODE)
The thermodynamic water heater can only heat the water during:
the programmed timer range,
