This Relay-25 fits in a standard single gang box. It is used in conjunction with the 4iE® Smart thermostat series as well as the Tempo thermostat, in order to expand the original 15 amp capacity. It is specifically designed for large applications beyond 800 sqft.

Yes. The box and mounting requirements are identical for all horizontal Warmup thermostats and the sensor is compatible. If you’d like to swap a 3iE for a 4iE or Tempo thermostat you will need to consult with a qualified electrician, as it requires handling line voltage wires when disconnecting and reconnecting.
There is no neutral leg on a double pole breaker and the polarity between the two sides does not match. This will cause the thermostat to trip and/or it will send too much voltage into a 120V heater.
When you have multiple floor heating systems being powered that require more than 15amps, you can use an additional 3iE as a relay as opposed to purchasing a separate generic relay which Warmup can supply.
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.
