Meaning
1 DHWcirculationpump100%Output A1 is switched by control accessories
(BM) if DHW circulation has been enabled. Output A1 is constantly switched if
no accessory controller is installed.
2 DHWcirculationpump50%Output A1 is switched by control accessories
(BM) in cycles if DHW circulation has been enabled. 5 minutes ON and
5 minutes OFF. Output A1 constantly cycles in 5 minute cycles when no
accessory controller is installed.
3 DHWcirculationpump20%
Output A1 is switched by control accessories (BM) in cycles if DHW circulation
has been enabled. 2 minutes ON and 8 minutes OFF. Output A1 cycles
constantly when no accessory controller is installed.
4 AlarmoutputOutput A1 is switched 4 minutes after a fault.
5 FlamedetectorOutput A1 is switched after a ame has been detected.
7 Fluegas/ventilationairdamperOutput A1 is always controlled before the fan
starts. The feedback is checked via input E1. If input E1 does not close, the fan
and burner will not start, and after two minutes FC8 will be generated. The ue
gas/ventilation air damper is controlled until the fan starts. If input E1 is interrupted
during burner operation, the burner shuts down. In case of a fault, e.g. pressure
switch, ame failure during operation etc., the ue gas damper is closed after the
ushing time has expired.
Input E1 must be programmed as ue gas/ventilation air damper.
With FC8, the fan is controlled with 65% of speed stage 1.
8 ExternalventilationOutput A1 is controlled inverted to the burner. Switching
OFF external ventilation (e.g. extractor fan) during burner operation is only
required, if the boiler is operated as open ue system.
9 Oilshut-offvalveOutput A1 switches simultaneously to the oil pump
11 ExternalpumpOutput A1 switches simultaneously with the heating circuit
pump. Use with, for example, system separation.
12 DivertervalveSynchronous control with input E1 (E1 = 8, burner blocking)
13 CirculationpumpCirculation pump is turned ON for 5 min. if input E1 (E1
= 6) is programmed as DHW circulation remote control and input E1 key is
closed
14 PumpwithexternalburnerdemandSimultaneous control with input E1 (E1
= 10, ext. burner demand)
