Mode
Mode AUTO :
This operating mode manages automatically the choice of energy allowing to maximize
economies while supplying a sufficient hot water comfort level.
The water heater analyses the water consumption of the previous days to adapt the hot water
production as required. It reacts to unplanned events by launching working cycles during the
day to assure enough hot water. The set temperature varies automatically between 50 and
62°C according to the consumption profile.
The water heater chooses preferably the heat pump. The electric backup can automatically be
added to provide the correct hot water volume.
Mode MANUAL :
This mode allows to define the desired hot water quantity by selecting the set temperature.
The set temperature is also displayed as equivalence of showers.
When the mode ECO is not activated, the water heater favors the operation of the heat pump.
However if the air temperature is low or the water consumption high, the electric backup can
be used at the end of the heating cycle to reach the set temperature.
When the mode ECO is activated, the water heater works exclusively with the heat pump in
the air temperature range of -5 to +43°C. The electric backup heater is not used. This function
maximizes the energy savings but can cause a lack of hot water.
Whatever setting of ECO, the electric backup heater is used automatically if the air
temperature is outside the working range to assure a sufficient hot water volume.
The BOOST mode :
this mode activates the heat pump and all other available energy sources
(boiler backup if set, electric backup) at the same time to reach the maximum set point of
62°C.
The ABSENCE mode :
this mode maintains the hot water temperature above 20°C by using the
heat pump. The boiler and electric backup can be used if the heat pump is not available.
6. Display of system informations
