The thermostats come with a 9’ sensor cable to detect the temperature under the floor finish. The end of the probe wire contains a capped sensor that should be evenly centered between two heating cables at least 12” into the heated area. At no time should the probe wire cross the heating cable.
While you can operate your floor heating system without the floor sensor probe it is better to have it installed. Click “Read More” for detailed information.
The ground wire of the heater(s) must be directly connected to the ground wire of the supply.
Our cable was tested and measured 0.5 mG at 1/2” (a typical distance between the cable and your feet). This measures at 1/200th of the acceptable value of 100 mG as established by the WHO and Intertek/ETL. It therefore complies with EN50366.
If your thermostat has no display and will not turn on when power button is pushed, the thermostat could be wired incorrectly. Click here for more details.
12 AWG or 18 AWG should be used depending on the distance from the controller. Click “Read More” for details.

Please verify that the circuit can handle the amount of amperage your heating system requires. Your thermostat can only handle up to 15 amps so if you are connecting multiple heaters to one thermostat location, you may need to use a relay and a larger breaker. Your or your electrician can find out the amperage rating of your specific floor heating system in installation manual or printed on the box. Note: Just because the Warmup thermostats are dual voltage, this does not mean you can supply any voltage to your heating system. You must supply the voltage supplied to the voltage of your specific heater.
The amperage capacity of the Resibox is 120A and for the Commbox it is 230 Amps. The Resibox has (4) of the 30A/2-pole contactors rated 120-277V for a total of maximum 120A load capacity. Click “Read More” for details.
