Valve
proving
0
Fuel valve 1 (V1) leaking
(fuel valve 2 with valve proving via X5-01)
For valve proving via X5-01 (gas pressure switch-min)
- Check to see if the valve on the burner side is leaking
- Check to see if the pressure switch for the valve proving is closed when gas pressure is present
- Check wiring to see if there is a short-circuit
1
Fuel valve 2 (V2) leaking
(fuel valve 1 with valve proving via X5-01)
For valve proving via X5-01 (gas pressure switch-min)
- Check to see if the valve on the gas side is leaking
- Check wiring to see if there is a short-circuit
2
Valve proving not possible
Valve proving activated, but DWmin selected as input function for X9-04 (check parameters 238
and 241)
3
Valve proving not possible
Valve proving activated, but no input assigned (check parameters 236 and 237)
4
Valve proving not possible
Valve proving activated, but 2 inputs assigned (set parameter 237 to DWmax or POC)
5
Valve proving not possible
Valve proving activated, but 2 inputs assigned (check parameters 236 and 237)
81 V1
leaking
Check to see if the valve on the gas side is leaking
Check wiring to see if there is an open-circuit
83 V2
leaking
Check to see if the valve on the burner side is leaking
Check to see if the pressure switch for the leakage test is closed when gas pressure is present
Check wiring for short-circuit
14 #
POC
0
POC
open
Check to see if the valve’s closing contact is closed
1
POC
closed
Check wiring
Check to see if the valve’s closing contact opens when valve is controlled
64
POC open – prevention of startup
Check wiring to see if there is a line interruption.
Check to see if the valve’s closing contact is closed
19
80
Combustion pressure, POC – start prevention
Check to see if pressure switch has closed with no combustion pressure present
Check wiring for short-circuit
20 #
Pressure switch-min (Pmin)
0
No minimum gas / oil pressure
Check wiring for line interruption
1
Gas shortage / prevention of startup
Check wiring for line interruption
21
0
Pressure switch-max (Pmax): Max. gas / oil pressure
exceeded
Check wiring to see if there is a line interruption.

Safety loop / burner flange
0
Safety loop / burner flange open
1
Safety loop / burner flange open / prevention of startup
3
Safety loop/burner flange, extraneous light – start prevention
5
Safety loop/burner flange, air pressure – start prevention
17
Safety loop/burner flange, combustion pressure – start
