Fitting of an underfloor heating floor thermostat

Follow the diagram below for the correct fitting of a floor sensor that is wired back to a thermostat.  You may or may not have this type of control in your system.

It is sometimes better to control the temperature of the floor than control the air temperature in the room.

Typical situations where this would be advantageous include:

1. Bathrooms which have an auxiliary heat source, such as a towel rail.
2. Swimming pool areas.
3. Saunas.
