SMART Energy Function :
A heat pump uses the available energy in the air and
transfers this energy through an exchanger around
the tank to the water. The heat pump performance is
higher when the exchange parameters are more
favorable; i.e. air temperature higher or tank
temperature
lower.
Our
regulation
evaluates
permanently the air and water temperature and what
energy source is more economical. The function
SMART Energy
can decide to start heating with the
heat pump and to finish heating up with the boiler
backup.

4. The operating modes.
AUTO:
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.
MANUAL – ECO Not activated:
The set temperature is fixed by the user between 50 and 62°C. The water
heater chooses preferably the heat pump. The electric backup can automatically be added to provide the
correct hot water volume.
MANUAL – ECO Activated:
The set temperature is fixed by the user between 50 and 62°C. The water heater
chooses preferably the heat pump to maximize the energy savings. The electric backup is allowed to work if
the air temperature is out of the operating range.
4.1 The installation mode « Heat pump only » :
MANUAL :
The set temperature is fixed by the user between 50 and 62°C. The water heater chooses
preferably the heat pump. The boiler backup can be activated automatically to provide the correct hot water
volume. If the backup through the boiler is not available (e.g. boiler switched off), the electric backup will be
activated.
4.2 The installation mode « Boiler backup » :
The water heater works only during the period when the solar system does not supply energy (when the solar
system signal is off). During the periods of solar production, the hot water production is operated with the
internal coil, the heat pump and the electric backup are not working.
MANUAL – ECO Not activated :
The set temperature is fixed by the user between 50 and 62°C. The water
heater chooses preferably the heat pump. The electric backup can automatically be added to provide the
correct hot water volume.
MANUAL – ECO Activated :
The set temperature is fixed by the user between 50 and 62°C. The water heater
chooses preferably the heat pump to maximize the energy savings. The electric backup is allowed to work if
the air temperature is out of the operating range.
4.3 The installation mode « Solar backup » :
The electric backup will never work if the parameter « Electric backup » is deactivated.
The Smart Energy function can be set on 4 different management levels:
The backup operates at the end of heating up in case of low air temperature (<7°C)
The backup operates at the end of heating up and ± early depending on air °C
The heat pump works on the start of heating up and stops ± early depending on air °C
The heat pump works on the start of heating up and for air temperature > 10°C.
