Common Support Questions

The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

Warmly Yours controllers incorporate built-in Class A GFCI protection for all new floor heating systems.  Class A GFCI provides personnel protection and trips when ground fault current exceeds 5 mA (milliamps).  Class B GFCI protection is pretty much obsolete, but older systems may still require it.  Warmly Yours controllers with built-in Class B GFCI provide equipment and circuit protection and operates when a fault to ground exceeds 15 mA.

If your thermostat is blank, the first thing to do is to test to see if voltage is present at the rear of the thermostat. If no power is reaching the thermostat, please inspect the circuit breaker powering the thermostat in the breaker panel, and verify that the breaker is a non-GFCI type. If it is a GFCI breaker, replace it with a non-GFCI breaker. If there is power entering the thermostat and it is blank, it will need to be replaced.
