No Heat and No Error Messages

If your floor is not heating and you are not getting an error message, the first step is to confirm programming. Is the target temperature higher than the current temperature? Please make sure that when you are programming the thermostat that the triangle displays on the screen or the red light comes on (heating indicators vary for each thermostat) during times when you would like your floor to heat. If this heating indicator does not turn on, check your programming. Make sure your target temperature is higher than the floor temperature reading.

It could also mean that your thermostat is connected to the internet but you have not registered the device as a room on the myheating app or the my.warmup portal. In this instance, you will need to gather your 4iE’s device number and enter a room at your location on your profile. 

Heater error will occur if the heating system is not properly wired to the thermostat. Please click “Read More” for details.
