Changeover of operating mode
· heating circuit
The operating modes of the heating circuits are switched to Protection mode via
terminals H1/H2 (e.g. using a remote telephone switch).
· Domestic hot water
DHW heating is locked only when using setting 1: HCs+DHW.
Heat generation lock
The heat source will be locked via terminals H1/H2.
All temperature requests made by the heating circuits and by DHW will be ignored.
Frost protection for the boiler will be maintained.
The chimney sweep function can be activated although 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. external lamp or horn).
Minimum flow temperature setpoint TVHw
The adjusted minimum flow temperature setpoint will be activated when the switch
connected to terminal H1 (e.g. an air heater function for a warm air curtain) closes its
contact.
Heat request
Heat generation receives heat requests in the form of voltage signals (DC 0...10 V).
The associated setpoint is to be adjusted on operating line 5954.
