My Floor has No Heat but There Are No Error Messages?
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.
If your programming is confirmed and your floor is not heating, consider what your subfloor type is. If your system has been installed on a concrete slab or over an unheated space and no insulation was used, downward heat loss will cause your heating system to warm your floor much more slowly. Downward heat loss will cause a delay in heating.
If you have confirmed your programming and insulation and are still experiencing issues, you should contact your electrician to do proper troubleshooting. Have your electrician check the resistance readings. Make sure the proper voltage is wired from your panel to the thermostat. The amperage of the heating system should match the amperage coming from the panel. Also check to make sure that all wiring is correct by having your electrician check the manual. Be sure to record all information gathered and contact Warmup for support if needed.
