4.50.2 Operation according to the time switch programs with
forward shift (d.h.w.)
Setting 1
For d.h.w. operation, the heating cricuits will be considered according to the setting
"D.h.w. assignment".
The switching times of the time switch programs are then used to change over between
the nominal d.h.w. setpoint and the reduced d.h.w. setpoint. The first switch-on point of
each period will be shifted forward in time by one hour.
With this d.h.w. heating program, it is also possible to select the number of charging
cycles per day. This also includes the forward shift of the switch-on times. Also refer to
"d.h.w. heating" in Index.

4.50.3 Operation according to the local time switch program 3
(d.h.w.)
Setting 2
For d.h.w. heating, time switch program 3 (d.h.w.) of the local controller is taken into
account. The set switching times of that program are then used to change over
between the nominal d.h.w. setpoint and the reduced d.h.w. setpoint. In that way,
d.h.w. is heated independent of the heating circuits.
With this d.h.w. heating program, it is possible to have a maximum of three heating
periods per day. There is no forward shift of the switch-on times.
