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

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.
