The DHW can be heated up to different setpoints. These setpoints are activated
depending on the selected operating mode, thus leading to different temperature levels
in the DHW storage tank.

Time program 4 / DHW
24h/day
The DHW temperature is constantly maintained at the nominal DHW setpoint,
independent of any time programs.
Example:
Time programs HCs
The DHW setpoint is switched between the nominal DHW setpoint and the reduced
DHW setpoint according to the heating circuits' time programs. The first switch-on point
of each period is shifted forward in time by one hour.
Example:
Time program 4 / DHW
For DHW heating, time switch program 4 of the local controller is used. 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 is heated independently of the
heating circuits.
