The functions of output A1 can only be scanned and adjusted with Wolf control
accessories with eBUS capability.
The following functions can be allocated to output A1:

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 output
Output A1 is switched 4 minutes after a fault.
5
Flame detector
Output A1 is switched after a flame has been detected.
7
Flue gas/ventilation air damper
Output 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 flue
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, flame failure during operation etc., the flue gas damper is closed after the
flushing time has expired.
Input E1 must be programmed as flue gas/ventilation air damper.
With FC8, the fan is controlled with 65% of speed stage 1.
8
External ventilation
Output 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 flue system.
9
Oil shut-off valve
Output A1 switches simultaneously to the oil pump
11
External pump
Output A1 switches simultaneously with the heating circuit
pump. Use with, for example, system separation.
12
Diverter valve
Synchronous control with input E1 (E1 = 8, burner blocking)
13
Circulation pump
Circulation 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 demand
Simultaneous control with input E1 (E1
= 10, ext. burner demand)
0, 6, 10, 15 have no function
