20.2 Assignment of d.h.w. heating
Operating line 125 is used to select for which controllers in an LPB system the d.h.w. is
heated or, in other words, which heating circuits get their d.h.w. from the same source.
With plant types 1–0 and 5–0, this setting is not required since they do not include
d.h.w. heating.
Operating line 125 Explanation
0 The d.h.w. is only provided for the heating circuit associated with
the own controller.
1 The d.h.w. is only provided for the heating circuits of the control-
lers with the same segment number that are connected to the
data bus (LPB).
2 The d.h.w. is provided for all heating circuits of the controllers
connected to the data bus (LPB).
The setting is active only when setting 1 (according to the space heating switching
program with forward shift) has been selected on operating line 101 (d.h.w. release).
