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 module.
Parameter HG14
Function output A1
Display Designation:
none none(factorysetting)
Output A1 is ignored by the control unit.
Circ 100 DHW circulation pump 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.
Circ 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.
Circ 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ame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congured,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.
Fluegas
damper
Fluegas/ventilationairdamper
OutputA1isactivatedrstbeforeeachburnerstart.Theburnerwill,
however, only be enabled after input E1 has been closed. Closed
contact E1 is a pre-requisite for enabling burner in central 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conguredforauegasdamper,inputE1is
automaticallyprogrammedforauegasdamperandblockedforother
settings.
Alarm Alarm output
When a fault has occurred and 4 minutes have passed, the alarm
outputisactivated.Thereisnonoticationofwarnings.
Extvent. Externalventilation
OutputA1isactivatedinverselytotheamesignal.SwitchingOFF
external ventilation (e.g. extractor fan) during burner operation is
requiredonlyiftheboilerisoperatedinopenuemode.

Externalfuelvalve
1)
Activates an additional fuel valve during burner operation.
OutputA1isactivatedfrompre-ushingofthedeviceuntilburner
shutdown.
HCP Heatingcircuitpump(canonlybeenabledviaHG40System
conguration12)
IfparameterHG40Systemconguration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.
1)
According to DVFG-TRF 2012 chapter 9.2, an additional on-site LPG valve is not required if it has been ensured that no
potentially hazardous quantity of gas can escape from the appliance. The CGB-2(K)-14/20/24 gas boilers meet these
requirements.
