Reheat setpoint
Desired reheat tank temperature, used:
▪ in Schedule + reheat mode, during reheat mode: the guaranteed minimum
tank temperature is set by the Reheat setpoint minus the reheat hysteresis.
If the tank temperature drops below this value, the tank is heated up.
▪ during storage comfort, to prioritize the domestic hot water preparation. When
the tank temperature rises above this value, domestic hot water preparation and
space heating/cooling are executed sequentially.
