Return difference

The room sensor has a max temperature of 45 degrees as a factory default. When the max temperature for the room sensor reaches 45 degrees and goes above this temperature, then the underfloor heating will switch off and an audible alarm will sound, the alarm will not turn off until the room sensor goes below 43 degrees.

Sensor Error Codes

When the error code “E1” shows up on the controller it indicates a room sensor failure or if the “E2” error code shows up on the controller it indicates a floor sensor failure. The thermostat will not heat until the error code is fixed.
