Installation of the floor sensor probe of the TH115 Floor Heating Thermostat

Insert the floor sensor probe through one of the two openings on the wall plate and connect the sensor wires to terminals 1 and 2.

The sensor cable must pass outside the electrical box and follow the wall down to the floor.

Position the sensor cable such that it does not come in contact with the floor heating wires. The sensor must be centered between two floor heating wires for best temperature control.

Do not staple the sensor head (the plastic end) to the floor. Doing so may damage the sensor. Any damage might not be noticeable during testing but can become apparent several days later.
