SunTouch SunStat Current Production Models
- Manufactured by SunTouch's parent company Watts Radiant.
- The thermostats can have different letters after the model number and refer to packaging or market area; but all are the same in function, features and look
- All SunTouch Thermostats are in 2 pieces - the “power base” which mounts to the wall, and the “Faceplate” which mounts to the power base. These items are not interchangeable and are not sold separately. If you ever need to replace or return a thermostat, you need to replace both pieces – never just change the faceplate.

If you want to add the accuracy and convenience of a floor sensor (included with the TEMPO but wasn't used with NDG) you can install the sensor in the floor – very carefully in a grout joint or from below; but don't damage your mat.
The easier solution is to set the Tempo to A mode; in “A” mode, the thermostat controls the ambient air temperature. This setting is useful if the floor temperature sensor is not installed.
