This sleek and intuitive iStat Thermostat boasts a range of convenient features as well as an effortlessly modern design, ideal for tying together an underfloor heating system efficiently and effectively. This unit combines ease-of-use with intelligent, intuitive functions, letting you get the most from your underfloor heating system.

The iStat uses powerful WIFI connectivity and a 2.4ghz frequency for optimal coverage, even through multiple walls, providing reliable connections to IOS and Android smart devices for adjusting the thermostat's features via the app. The sensitive touchscreen, combined with a simple Key Lock feature, ensures your settings stay set. Even if you leave the window open, the thermostat can detect rapid changes in temperature thanks to the Open Window feature, shutting off proactively for 15 minutes. The iStat also has a range of budget-friendly features to help keep your home heated, combining anti-freezing and Holiday Modes, allowing considerable autonomy.

Features & Benefits:

  • Reliable and powerful WIFI connectivity for optimal coverage
  • Sensitive touchscreen for accurate and effortless input
  • Key Lock function stops accidental changes
  • Holiday Mode keeps heating under control when you are away
  • Adaptive Learning changes the way it heats to adapt to your heating system
  • Sleek modern design keeps 'smart home' aesthetics consistent
  • Open Window feature guards against wasting energy

Please note:

  • A 35mm Single gang box will be required to house the thermostat. The thermostat includes the 3m floor sensor which is in the same box as the thermostat. The wireless function operates over a 2.4ghz WiFi wireless frequency. Please ensure that this is enabled on your router as some routers are supplied with only the 5ghz frequency active as default. Devices such as thermostats use the 2.4ghz frequency as although it has a slower data rate (which doesn't effect the performance of the thermostat), its is better at penetrating solid objects and provides better coverage.
