Product Description:

SunTouch’s 15 ft Floor Sensor (Model 500110, Ordering Code 81009178, UPC 840213091095) is the official SunStat-compatible temperature sensor designed for precise in-floor temperature control in SunTouch electric radiant floor heating systems. This low-profile floor heating thermostatic sensor is engineered to be embedded directly in mortar, giving accurate floor temperature readings right where the heat is generated, which helps your SunStat programmable or non-programmable thermostat maintain a comfortable, even heated tile floor in bathrooms, kitchens, entryways, and other living spaces. 

Using a 10k NTC thermistor design with double insulation and Class 2 construction, this SunTouch floor sensor delivers reliable, long-term performance as part of your radiant floor heating system, protecting both the thermostat and heating cable by monitoring real floor temperature instead of just air temperature. It is the same style of in-floor temperature sensor supplied with many SunTouch TapeMat, WarmWire, and ConnectPlus underfloor heating kits, making it the ideal replacement floor sensor or spare sensor wire if the original probe is damaged or misplaced during installation or tile replacement. 

The SunStat floor sensor wire is approximately 15 feet in length, giving ample reach from the thermostat location on the wall down to the heated floor area so you can route the in-floor temperature probe to the ideal sensing point between heating cables or mats. This flexible floor heating temperature probe installs easily in standard thin-set mortar beds over concrete or plywood subfloors and works with SunTouch SunStat thermostats that accept a 10k NTC floor sensor, providing a plug-and-play compatible solution for most SunTouch electric floor heating controls. It is widely used as an extra SunStat floor sensor for preventive maintenance, an emergency spare floor sensor wire for radiant heat repairs, and a universal SunTouch temperature sensor for tile and stone coverings in any radiant floor heating installations. 

Whether you are installing a new electric floor heating system or servicing an existing heated bathroom floor, this insulated floor sensor helps protect your investment by giving accurate feedback to the heating thermostat, helping prevent overheating of tile, grout, and flooring materials. Contractors and DIY homeowners alike rely on this SunTouch replacement floor sensor for WarmWire cable systems, TapeMat heated floor mats, and other SunTouch electric floor heating accessories when they need a dependable underfloor heating replacement sensor that matches factory specifications. When paired with a SunStat programmable thermostat, this in-floor heating sensor supports energy-efficient operation, stable comfort, and consistent radiant warmth, making it an essential small accessory that keeps a premium SunTouch heated floor system running safely and smoothly for years.
