electric underfloor heating (UFH) systems available. Thermotouch can replace your existing underfloor heating thermostat and is compatible with many of the most popular thermostat brands’ floor sensor probes including those rated at: • 6.8kΩ @ 25°C • 10kΩ @ 25°C • 12kΩ @ 25°C • 15kΩ @ 25°C • 33kΩ @ 25°C Replacing an existing thermostat? Contact the manufacturer’s technical department and ask for the rating of the floor sensor at 25°C.

Check you’ve got everything: • Thermotouch 4.3dC thermostat • Floor sensor probe (3m) • Floor sensor conduit (3m) • Fixing screws • Manual and warranty information You will also need: • Electrical screwdrivers • Deep electrical back box • Electric testing meter

At this stage it its likely that an electric underfloor heating system has been installed and a back box is already in place. The underfloor heating cold tail should be pulled up through the back box, and the sensor probe installed (in the conduit provided) within the wall cavity or pre chased channel in a solid wall.

Thermotouch can be installed up to 50m away from the underfloor heating system it is controlling, provided that the floor sensor is used to control the temperature. Underfloor heating cold tails and floor sensor probes can be extended up to 50m. 50m max.
