The DHW temperature is constantly maintained at the nominal DHW setpoint,
independent of any time programs.
Example:
0 6
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:
0 5 6
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 is heated independently of
the heating circuits.

When both space heating and DHW demand heat, the "DHW priority" function ensures
that during DHW charging the heat generation capacity is used primarily for DHW.
Absolute priority
The mixing and pump heating circuit stay locked until DHW heating is finished.
Shifting priority
If the capacity of the heat source is not sufficient, the mixing and pump heating circuit
will be restricted until DHW is heated up.
