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:
Explanation
1 DHW circulation pump 100%
Output A1 is switched by control accessories (BM) if DHW circulation has
been enabled. Output A1 is constantly enabled when no accessory controller
is installed.
2 DHW circulation pump 50%
Output A1 is switched by control accessories (BM) if DHW circulation has
been enabled. 5 minutes ON and 5 minutes OFF. Output A1 constantly cycled
in 5 minute cycles when no accessory controller is installed.
3 DHW circulation pump 20%
Output A1 is switched by control accessories (BM) 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 controlled after a fault and expiry of 4 minutes.
5 Flame detector
Output A1 is controlled after a flame has been recognised.
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 DHW circulation pump
DHW circulation pump ON for 5 mins if input E1 (E1 = 6) is programmed as
DHW circulation pushbutton 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 are without function.
