Changeover of operating mode
•
Heating circuit
The operating modes of the heating circuits are switched to Protection mode via the
H… terminals (e.g. using a remote telephone switch).
•
DHW
DHW heating is locked only when using setting 1: HCs+DHW.
Heat generation lock
The heat source is be locked via the H… terminals. All temperature requests from the
heating circuits and DHW are ignored. Frost protection for the boiler is maintained.
The chimney sweep function can be activated although the heat generation lock is
switched on.
Error / alarm message
Input H1 generates a controller-internal error message.
If the “Alarm output” (relay outputs QX2-4, operating lines 5891 – 5894) is appropriately
configured, the error message will be forwarded or displayed by an additional contact
(e.g. an external lamp or horn).
