Room temperature at which the night heating function is activated: the
AH unit which has been shut down starts up at full output and the
dampers go to the night heating position (see p. 34 N.HeatPosit).
When the room temperature rises by the amount of the hysteresis the
controller shuts down the AH unit and the dampers go to the idle time
position.
Attention! The exhaust controlled AH unit must have a room sensor
connected to it if the night heating function is going to be taken into
use.During night heating the room sensor controls the controller(p.25).
