2.38 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.
In normal heating operation, d.h.w. heating can be assigned to the time switch
programs of the various zones. In a system, it is thus possible to have either decentral
or central d.h.w. heating which takes into account the switching times of the local, the
segment or system heating circuits.
This is active only when the setting on line 121 reads 1, unless holiday mode is
activated (also refer to "Holiday mode" below).
Setting range Unit Factory setting
0...2 - 2
Through this setting, the time switch programs of the respective heating circuits will be
considered for d.h.w. heating.
0 Local heating circuit:
D.h.w. heating according to the time switch program of the local heating circuit
1 All heating circuits in the segment:
D.h.w. heating according to the time switch programs of the segment heating
circuits
2 All heating circuits in the LPB system:
D.h.w. heating according to the time switch programs of the system heating
circuits
If a room unit triggers holiday mode, the effect will be the following, independent of the
d.h.w. heating program (line 121):
Setting on line 123 Effect
0 Local heating circuit No d.h.w. heating when the local heating circuit
is in holiday mode
1 All heating circuits in the
segment
No d.h.w. heating when all heating circuits in the
segment are in holiday mode
2 All heating circuits in the
system
No d.h.w. heating when all heating circuits in the
system are in holiday mode
This means that even if the d.h.w. would have to be heated according to the d.h.w.
program (line 121), the holiday function may lock d.h.w. heating. Only the frost
protection function will remain active.
