12 Troubleshooting
12.1. Fault lock-out
If it recognises one of the following fault features, the heater will conduct
a fault lock-out.
– If there is undervoltage, approx. 10 – 25 seconds after the voltage
drops below the switching threshold.
– If no combustion starts within approx. 30 seconds after the heater is
switched on
– If the fuel supply is interrupted for more than 10 seconds during
heating operation
– If the heater is switched off by the temperature fuse or the
temperature limiter due to overheating. In such a case, the
temperature fuse must be replaced with another of the same type
(note the colour code) or the button on the temperature limiter must
be reset (after cooling to below 60 °C).
