The Smart Grid function is NOT active.
Forced off :
▪ The unit forces OFF the compressor and the backup heater.
▪ The safety functions (water pipe freeze prevention, drain prevention, room frost
protection, tank disinfection) and defrost are NOT overruled (capacity will not be
limited for these functions)
Recommended on :

setpoint is reached, the unit can choose to buffer energy from the photovoltaic

temperature.

capacity of the unit is limited to what the photovoltaic panels are providing:
