The Standard features of the SunStat PRO Programmable Thermostat (500670) make it a good choice for operating your floor heating system.
This thermostat has built-in Ground Fault Protection for your safety and is fit for use in the US and Canada according to ETL to UL standards. The thermostat senses the floor temperature via a 15-foot Floor Sensor Wire which is included. In most areas, you don't even need another GFCI circuit. Enjoy the sleek design of the backlit display with the programming buttons simply hidden behind a single door.
SunStat PRO is a Dual Voltage thermostat which means it's suitable for 120v or 240v and you don't have to worry about its compatibility with your floor heating system.
Manufactured in-house by SunTouch (not outsourced like many other brands), last updated in 2007, we have newer Direct Replacement Thermostats with longer warranties & more features, if you prefer.

- Installed first unit in 2010. Works well, easy to program Review by coldfoot
- I now have 3 units installed. All work well. Easy to program and does not forget settings when power is turned off. I do not heat the room with the floor, just set temperature to near ambient and feet are always warm. Builder wanted to install in kitchen and I did not think it was cost effective, but after one walk through the kitchen barefoot on a winter night, I now would install heat under any tile floor!
