Thermostats & Sensors

A floor heating thermostat is necessary to control your radiant heat system. Most of our thermostats are dual-voltage and include a 5ma GFCI, unlike models from online warehouse retailers. A thermostat is capable of a 15-amp load; adding a power module or relay will increase system load capacity. Each includes a floor sensor, but a backup is recommended. Select 1 thermostat for each zone desired. Contact an expert for guidance.
