The thermostat has three different modes as it has a built in temperature sensor and a remote floor sensor (must be connected when used with
electric underfloor heating). The unit can operate on Air temperature (A mode), Floor temperature (F mode) or Air and Floor temperature (AF mode).
‘A’ mode should not be used with electric underfloor heating, it can be used to control other heating devices.
‘AF’ mode for when the underfloor heating is used as a primary heat source, but a floor temperature limit is needed.
‘F’ mode for when the thermostat is outside the heated room e.g. a bathroom, or when being used as a secondary heat source.
Note: These can be changed in ‘General Settings’ on the last page of these instrauctions.
