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.
Both 120Vac and 240Vac Warmup heating cable(s) output the same amount of power (wattage) per square foot (13.1 watts), so, the only difference between 120Vac and 240Vac heating cable(s) is the amount (ft2) of heating cable you can attach to one 15A thermostat.

No, you should never shorten the heating wire. Click “Read More” for details.
When slight damage is caused to the wire, a visual assessment needs to be made. Read more.
