Forced off
:
▪ The unit forces OFF the compressor and the backup heater.
Recommended on :
▪ In case the space heating/cooling request is OFF and the tank temperature
setpoint is reached, the unit can choose to buffer energy from the photovoltaic
panels in the room (only in case of room thermostat control) or in the storage
tank instead of putting the photovoltaic panel energy on the grid.
In case of room buffering, the room will heat up or cool down to the comfort
setpoint. In case of tank buffering, the tank will heat up to the maximum tank
temperature.
