Trouble-shooting
Control of functioning:
If heat is not turned on by activating the thermostat, check the residual
current device (RCD) and fuses before contacting an authorized electrician .
Trouble-shooting chart:
Reserved for the electrician!
Control of functioning:
- Check mains voltage on clamps 1 and 2 .
- Tighten up clamps 1 and 5 .
- Measure the resistance in the heating cable and calculate the output:
- If the sensor wires, clamps 6 and 7, are dismounted, the red indicator
lamp should light up and the thermostat should switch on . If not, the
thermostat is defect .
- Measuring of sensor with ohmmeter must give a certain resistance
value in relation to the ambient temperature - see technical data chart .
- If the sensor wire clamps 6 and 7 are short-circuited, the indicator
should turn green, and the thermostat should be switched off . If not,
the thermostat is defect .
