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 ame 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 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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 ue 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).
