Thermogroup offer three different programable Thermostats, designed for providing full control over your Underfloor Heating.
The below video an information will help you explore the range to find the most suitable Thermostat.
Firstly we would like to make clear, that Underfloor Heating requires a Thermostat. By Australian regulation, you need to be able to control the temperature, as the maximum temperature the floor heating can operate at is 28°C. The thermostat controller allows you to set when the heating is on or off and what temperature you wish the floor or room to achieve.
