Hg14: Function Output A1 - Wolf COB-2 Operation Instructions Manual

Parameter settings
Ex f msg External fault (e.g. fault contact of condensate removal pump)
w/o sh When contact E1 is open, fault message 116 is generated.
Heating and DHW heating will remain active.
The fault message is cancelled by closing contact E1.

HG14: Function output A1

Read and configure parameter HG14 using the BM-2 programming unit or the AM display module directly
at the heat generator.
Display Description
None None (factory setting)
Output A1 is ignored by the control unit.
DHWcirc DHW circulation pump 100%
100 Output A1 is switched by the time program in the control accessory if DHW circulation has
been enabled.
Output A1 is constantly switched if no accessory controller is installed.
DHWcirc DHW circulation pump 50%
50
Output A1 is switched cyclically by the time program in the control accessory if DHW
circulation has been enabled.
5 minutes ON, 5 minutes OFF. Output A1 is switched cyclically if no accessory controller is
installed.
DHWcirc DHW circulation pump 20%
20 Output A1 is switched cyclically by the time program in the control accessory if DHW
circulation has been enabled.
2 minutes ON, 8 minutes OFF. Output A1 is switched cyclically if no accessory controller is
installed.
Flame Flame detector
Output A1 is switched after a flame has been recognised.
Flue gas Flue gas/ventilation air damper
damper Output A1 is switched first before each burner start. The burner will only be enabled after
input E1 has been closed. Closed contact E1 is a prerequisite for enabling the burner in
heating, DHW and emissions test mode.
A fault is generated (FC8) if output A1 is switched and input E1 does not close or open within
1 minute.
If output A1 is configured as a flue gas damper, input E1 is automatically programmed as a
flue gas damper and disabled for other settings.
Zirkomat Zirkomat (DHW circulation remote control)
Output A1 is activated for 5 minutes when input E1 closes.
After input E1 has been switched off and 30 minutes have elapsed, the Zirkomat function is
re-enabled for the next operation.
Alarm Alarm output
If a fault has occurred and 4 minutes have passed, the alarm output is activated. There is no
notification of warnings.
Ext vent. External ventilation
Output A1 is switched inversely to the flame signal.
Switching off external ventilation (e.g. extractor fan) during burner operation is required only
if the heat generator is operated in open flue mode.
Fuel valve External fuel valve
Activates an additional fuel valve during burner operation.
Output 1 is activated from the pre-purging of the heat generator until burner shutdown.
HCP Heating circuit pump
For HG40 system configuration 1, output A1 is switched parallel to the feed/heating circuit
pump.
If HG40 system configuration is set to 12, output A1 is automatically enabled as the output
for a heating circuit pump (direct heating circuit).
