Parameter HG14
Function output A1

24. Parameter description
The functions of output A1 can only be checked and set directly on the boiler
under parameter HG14 using the AM display module or BM-2 programming unit.
Display Designation:
None None (factory setting)
Output A1 is ignored by the control unit.
Timer 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.
Timer 50 DHW circulation pump 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.
Timer 20 DHW circulation pump 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 activated after a flame has been recognised.
Zirkomat Zirkomat (DHW circulation remote control)
Output A1 is activated for 5 minutes when input E1 closes. If output
A1 Zirkomat is configured, input E1 is automatically set to 'DHW
circulation remote control' and is blocked for further settings. When
input E1 has switched off and 30 minutes have elapsed, the remote
control function is re-enabled for the next operation.
Fl. gas Flue gas/ventilation air damper
damper Output A1 is activated first before each burner start. The burner will,
however, 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.
If output A1 is activated and does not close input E1 within 2 minutes,
a fault is generated (FC 8).
If output A1 is deactivated and does not open input E1 within
2 minutes, a fault is generated (FC 8).
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.
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 activated 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 External fuel valve
valve Activates an additional fuel valve during burner operation.
Output A1 is activated from pre-flushing of the device until burner
shutdown.
HCP Heating circuit pump (can only be enabled via HG40 System
configuration 12).
If parameter HG40 System configuration is set to 12, output A1 is
automatically enabled as the output for a heating circuit pump (direct
heating circuit). This function cannot be selected separately via HG14.
