SENSOR FAULT

SENSOR FAULT

The thermostat may show an e1 or e2 on the display. This is because the sensor is not connected correctly; it may be due to an open circuit or the heat mat may be connected in terminals 5 and 6. Check the resistance of the sensor, it should be 12kΩ@25°C. If the mat was inadvertently connected in 5&6 the resistance would be between 21Ω and 756Ω, these low resistances will cause the thermostat to display an error.
Once the resistances are checked, replace the sensor or mat as appropriate.
