2/3 Interlock circuit has been interrupted
An external safety device connected to the terminals (ST 9.3-9.4) has been triggered. Check and
repair this safety device.
4 No fl ame signal when the burner starts
No fl ame is detected within the preset safety time when burner starts. Restart is possible if pro-
grammed.
5 Flame signal lost during operation
When the burner is in operation, the measured ionisation has fallen below 1µA.
6 Limit temperature monitoring system has been triggered
The fl ow temperature has risen above the value set for the same, or the water fl ow is too low.
7
The maximum fl ue gas thermostat has been triggered
The fl ue gas temperature has gone above 100°C. Repair the fault and press reset.
11 Faulty fl ame signal
An ionisation signal of higher than 1µA has been measured while the burner was not in operation.
Repair the fault and press reset.
12
Defective fl ow temperature sensor
The measured resistance value of the fl ow temperature sensor is outside the range of -10 and
+126°C. Repair the fault and press reset.
13 Defective fl ue gas temperature sensor/lockout input is interrupted
The resistance value measured by the fl ue temperature sensor lies outside the range of -10 and
+126°C. Repair the fault and press reset.
An external safety device connected to the terminals (1-3) has been triggered. Check and repair
this safety device.
14
Defective hot water sensor
The resistance value measured by the hot water sensor lies outside the range of -39 and +110°C.
Repair the fault and press reset.
15 Defective external sensor
The resistance value measured by the external sensor lies outside the range of -39 and +110°C.
Repair the fault and press reset.
20/21 Fault in gas valve control system
After the burner has been switched off, an ionisation signal of more than 1µA is still measured for
5 seconds. Repair the fault and press reset.
24
Faulty minimum fan speed
During the pre purge, a specifi c minimum fan speed is not achieved. Repair the fault and press
reset.
25
Faulty maximum fan speed
A specifi c maximum fan speed has been exceeded, thereby failing to meet an ignition prerequi-
site. Repair the fault and press reset.
26
Faulty standby fan speed
The fan speed is too high (300 rpm) when the fan is switched off. Repair the fault and press reset.
30
CRC fault in control system parameters
An EEprom fault has arisen in the stored control parameters. Check and change this parameter
set.
