4.226 Assignment of d.h.w. heating
•
Assignment of d.h.w. heating to the respective consumers
•
All relevant time switch programs are taken into consideration
•
Controllers in holiday mode are taken into consideration
Determines the consumers for which d.h.w. will be heated and which time switch pro-
grams will be appropriately considered, also checking whether the relevant controllers
are in holiday mode.

Depending on the selection made, d.h.w. will be heated for the following consumers:
0
For the local consumer only (RVP540 / RVP550)
1
For all consumers (controllers) in the same segment
2
For all consumers (controllers) in the LPB system
(only if the controller is in segment 0)
In the case of d.h.w. heating according to the heating circuit time switch program (oper-
ating line 771, setting 1), the time switch programs are used from the appropriate range
for the release of d.h.w. heating at the nominal temperature setpoint, based on the con-
sumers selected here.
With all settings (operating line 771, setting 0 - 2), it is checked whether the controllers
of the selected range are in holiday mode. Controllers in holiday mode will
not
be con-
sidered for d.h.w. heating.
If all controllers in the selected range are in holiday mode, d.h.w. heating will
not
be
released (the d.h.w. button flashes if it was previously switched on). Only the frost pro-
tection function will remain active (see chapter 6. “General control processes”).
