Frequently Asked Questions

What is a floor sensor?

A floor sensor is a small probe that is installed beneath the floor, between two runs of heating cable. This is connected to the Thermostat and gives an accurate reading of the floor temperature.

What is the flexible conduit for? Do I need to install it?

We recommend the use of a conduit for the floor sensor so that in the event of a floor sensor failing or the thermostat being upgraded, the floor sensor can be replaced without damaging the floor covering. If this is not possible we recommend installing a second-floor sensor as a spare.

What temperature should I set my underfloor heating at?

Every situation is different however it is recommended to set your underfloor heating to 24°C to begin with. After testing for several days increase or decrease the temperature to find your comfort temperature. Please note a decrease of 1°C may not affect the comfort or warmth of the floor enough to make it noticeable but can help to reduce running costs.

Can I control multiple zones with one controller?

No, each zone that you want to have individual control over needs to have its own separate controller.

How long should the floor heating be left on for?

The length of time depends on your lifestyle, the system used and the desired temperature.

Do I need to purchase a floor sensor?

No, every Thermotouch Thermostat is supplied with a compatible floor sensor, so this does not need to be purchased separately.

Can I control my underfloor heating and towel rail from one controller?

Yes, with our Thermotouch 4.3dC dual control thermostat, you can individually control both your underfloor heating and towel rail from the single controller.

Can I control my underfloor heating using C-Bus?

Yes, ensure that you purchase the manual controller with your underfloor heating and this can be connected to and controlled by your C-Bus system.
