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.

If your floor is not heating and your thermostat is functioning properly, test to see if proper voltages are present at the transformer.  If 24 VAC is not being returned by the transformer, then it either needs to be replaced or checked to ensure that the internal secondary circuit breakers have not been tripped and are functioning properly.  Contact Warmly Yours technical support at 1-800-875-5285 for further assistance.
