24h/day
The DHW temperature is maintained at the nominal DHW setpoint, independent of any
time programs.
Example:
Time programs HCs
The DHW setpoint changes between the nominal DHW setpoint and the reduced DHW
setpoint according to the heating circuits’ time program. The first switch-on point of
each phase is shifted forward in time by one hour.
Example:
Time program 4/DHW
For DHW heating, time program 4 of the local controller is taken into consideration. The
set switching times of that program are used to switch between the nominal DHW
setpoint and the reduced DHW setpoint. This way, the DHW storage tank is charged
independently of the heating circuits.
