The thermostat gives you full control over your underfloor heating, directly adjusting the valves to regulate heat distribution. Using its dry contact relay, it can activate heat sources like gas boilers or pellet stoves. No matter your setup, this thermostat adapts to your needs.

Electrical underfloor heating with another Shelly
Control your electric underfloor heating by signaling a connected Shelly relay to turn on or off based on the room’s temperature and humidity.

Full safety of your heating installation
The Anti-freeze function of the thermostat ensures that even if you're away from home, your heating installation is safe. It ensures temperature in the room never gets too low thus preventing damage to the heating pipes and your home.

Lower Energy Bills
Equipped with full Shelly capabilities, this thermostat will save energy without sacrificing comfort. Temperature offsets ensure accurate heating, while smart schedules and scenes let you heat your home only when needed—based on time, sunrise/sunset, or automation with other devices. This helps you use less energy and lower your bills.
