The thermostat & receiver has lost their pairing. Please refer to page 4 of the instruction booklet to re-bind. Please ensure you refer to the installation video to ensure receiver & stat are positioned correctly to prevent reoccurrence.

Don’t worry. The flame symbol is purely the thermostat receiving information, it is not an indicator of action.

This could be due to numerous reasons, some of the most common are listed below, but please ensure you refer to the installation & trouble shooting videos which will highlight some things to be considered.

Are the thermostatic radiator valves (TRVs) set too low? If the TRV is restricting the amount of heat allowed in the radiator then the thermostat will continue to unsuccessfully call for heat.

Is your thermostat placed in a position that will effect performance (i.e. placed in direct sunlight, above a radiator or close to another heat source) if the thermostat feels warm enough, it will not call for heat.

Has the thermostat been programmed correctly to call for heat at the right time of day? (refer to programming video for guidance)

Ensure the programming is calling the right amount of heat at the right times of day (refer to programming video for guidance).

Ensure the room where the thermostat is placed has the thermostatic radiator valves set correctly, if the one in that room is set too low & the remainder of the house has them set high, then the thermostat will keep calling for heat as the room is in won’t get to the required temperature.

Use the middle button to change “auto” to “manual” Once done, simply press the up/down buttons to required temperature.
