Power supply
The functions of output A1 can be scanned and adjusted with Wolf control accessories with eBUS capability.
The following functions can be allocated to output A1:
Code Explanation
0
N/A
No activation of output A1
1
DHW circulation pump 100%
Controller (e.g. BM) activate output A1 when DHW is enabled.
Output A1 is constantly activated when no controller is installed.
2
DHW circulation pump 50%
Controller (e.g. BM) cycles output A1, when DHW is enabled. 5 minutes ON and 5 minutes OFF.
Output A1 is cycled constantly in 5 minute intervals when no controller is installed.
3
DHW circulation pump 20%
Controller (e.g. BM) cycles output A1, when DHW is enabled. 2 minutes ON and 8 minutes OFF.
Output A1 is cycled constantly when no controller is installed.
4
Alarm output
Output A1 is activated after a fault and expiry of 4 minutes.
5
Flame transmitter
Output A1 is activated after a flame has been recognised.
6
Cylinder primary pump
(only for central heating boilers) (factory setting for A1)
Output A1 is activated when the cylinder is heated up.
7
Ventilation damper
Output A1 is activated before each burner start. The burner will, however, only be enabled after input E1
has been closed.
Important:
In any case, input E1 must also be
programmed as „Ventilation damper“!
The feedback to input E1 must be made with a zero volt contact (24V). Otherwise, use an on-site relay
for potential separation.
8
External ventilation
Output A1 is activated inverted to the gas combination valve.
Switching off external ventilation equipment (e.g. extractor fan) during burner operation is only required, if
the boiler is operated as open flue system.
9
External LPG valve
Output A1 is activated in parallel to the gas combination valve.
10
External pump
Output A1 switches synchronously with the heating circuit pump (HKP). Use with, for example, system
separation.
