Release of d.h.w. heating

14.5.1 Function

Operating line 123 is used to select the times at which d.h.w. heating shall be re-
leased. Released means that the storage tank is recharged whenever there is a
need.
When using this function, d.h.w. heating can be prevented during nonoccupancy
times (e.g. at night or during holiday periods).
If, in the summer, d.h.w. heating takes place in alternating mode with an electric
immersion heater, the latter is continuously released – independent of the setting
made on operating line 123 – that is, 24 hours a day.
Mechanism of d.h.w. release:
1 D.h.w. button
2 Type of charging (via heating system/electric immersion heater)
3 D.h.w. heating via heating system
4 D.h.w. heating via electric immersion heater
5 D.h.w. heating

14.5.2 Release programs

Release of d.h.w. heating takes place at the following times, depending on the set-
ting made on operating line 123:
Setting D.h.w. heating is released ...
0 continuously (24 hours a day)
1 according to one or several heating programs
2 according to scheduler program 2 of own controller
With setting 1, release of d.h.w heating depends on the setting made on operating
line 121. In the case of several heating programs, d.h.w. heating is released if at
least one of the controllers involved provides heating to the NORMAL temperature
according to its heating program (independent of operating mode) and does not
operate in holiday mode.
Release of d.h.w. heating is shifted forward by 1 hour against the times of the heat-
ing program. When optimized switching on is active, the optimized switch-on times
apply – and not the times entered.
The release of d.h.w. heating is explained on the basis of 2 examples, where con-
trollers A and B are interconnected via data bus:
