Frequently Asked Questions

Although each circumstance is unique, it is recommended that you start by setting your underfloor heating to 24°C. Increase or lower the temperature after several days of testing to discover your comfort temperature. Please keep in mind that a 1°C drop in temperature may not have a significant impact on the comfort or warmth of the floor, but it can help to save operating expenses.

The length of time depends on your lifestyle, the system you're using, and the temperature you want to achieve.

A floor sensor is a small probe that is placed beneath the floor, in the space between two lengths of heating cable. This is connected to the thermostat and provides a precise temperature readout of the floor.

Yes! Thermogroup's Underfloor Heating Thermostats include a Floor Sensor as well as a 20mm flexible conduit to install the sensor in, making it easier to repair if necessary. The Floor Sensor and Conduit are located beneath the unit in your Thermostat box.

The installation of a conduit for the floor sensor is recommended so that if a floor sensor fails or the thermostat is upgraded, the floor sensor can be replaced without causing damage to the floor covering. If this is not possible, a second-floor sensor should be installed as a backup.

Yes, our Thermotouch 4.3dC dual control thermostat allows you to manage your underfloor heating and towel rail separately from a single controller.

No, you'll need an unique controller for each zone you want to have individual control over.

Yes, make sure your underfloor heating comes with a manual controller that can be connected to and controlled by your C-Bus system.

The electrician will need to connect mains electricity to the thermostat site before roughing in for our underfloor heating and controller. The electrician will next run two 20mm conduits from the thermostat position to the floor, one for the Underfloor Heating Cold Tail and the other for the Floor Sensor. Please see our Conduit Requirements pdf for more information and a graphic representation.

Although it is absolutely safe to wire several rails to a single controller, and many clients do so when they have many rails in a single room, it is crucial to realize that you cannot control these rails on separate schedules from the single controller. While the 4.3dC Dual Controller can manage both underfloor heating and towel rails independently, it cannot handle several rails at the same time. The on/off schedule for several tracks connected to this device will be the same. You'll need to wire the rails to distinct timers or switches if you want to control them independently.
