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.
