Calculation = the set flow temperature is calculated according to the heat curve and the set room
temperature T.room standard or T.room setback.
Frost protection calculation (with delay) = the set flow temperature is calculated according to the
heat curve and the set room temperature T.room.frost.
with delay means that frost protection can only be activated after the delay if triggered via the
outside temperature threshold when changing from standard to setback mode.
