Changeover of all controllers in the same segment
– With segment 0, setting 0 must be made on operating line 145
Prerequisite:
(range of action of segment); with the other segments, the setting
on operating line 145 has no impact.
– The contact must be connected to the master controller in
segments 0 to 14
Possible addresses: Device address 1
– All controllers in the same segment switch to operating mode
Effect:
– With setting 0, d.h.w. heating is switched off in the entire segment;
with setting 1, it is released in the entire segment
– With all controllers in the same segment, operating mode
changeover with the buttons is no longer possible
– When the contact of the remote telephone switch opens, all
controllers will return to the operating mode selected last
– Buttons

Heat generation lock - Setting 3

4.61.3
The heat sources connected to the PPS will be locked when contact H1 closes (e.g. via
ripple control).
All heat demand signals from the heating circuits connected to LPB and from the d.h.w.
storage tank connected to the RVA47.320 will be ignored while frost protection for the
boiler will remain ensured.
However, a local d.h.w. storage tank connected directly to the BMU can still trigger
d.h.w. heating.
The chimney sweep function can be activated directly on the BMU although the heat
generation lock is switched on.
All at LPB connected heat generations are not applied from the heat generation lock.
The setting for this function must be made at the BMU.
