Installing the Thermostat
• A conduit should be in place prior to installation. This conduit holds the sensor probe allowing it to
be removed where necessary.
• Ensure the floor sensor is installed running to the Thermostat location as the unit will be non-
operational without a floor sensor installed.
1. Remove the temperature dial using a flathead screwdriver.
2. Unscrew the captive screw situated to the left under the temperature dial (see Fig. 1 overleaf)
using a cross head screwdriver and remove the face plate.
3. Wire in the sensor probe, mains cable and Underfloor Heating cold tail as per the wiring diagram
above. Ensure that the wiring is adequate for the total load of the Underfloor Heating system.
4. Secure the back plate and main body to the back box with the 3.5mm screws provided. Tidy the
cables during installation to avoid entrapment and cable damage.
5. Reposition the face plate surround and tighten the captive screw.
6. Replace the cap, making sure the dial goes back in the correct temperature position.
