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.

To reset the ground fault protection, switch the CT230 OFF and back ON, or cycle the circuit breaker off and on. The TEST light will turn off if the ground fault protection is functioning properly. If the TEST light comes back on, contact Warmly Yours at 1-800-875-5285 and speak to a technical support representative to help further troubleshoot your system.

Verify that the master thermostat is calling for heat. If it is and the light does not illuminate, this means that the test has failed. Cut power to the heating system at the main electrical panel, have a qualified electrician verify the installation and, if necessary, replace the CT230.

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. Verify that the power module power switches are in the ON position. Test for 12VDC across the 12VDC screw and the GROUND screw at the back of the thermostat. Here is a wiring diagram: https://www.warmlyyours.com/en-US/publications/MASTER-THERMOSTAT-W-POWER-MODULES-WIRING-DIAGRAM-B.pdf
If no power is reaching the thermostat, please test for 12VDC across the 12VDC and GND output at the front of power module base that is supplying power to the thermostat (the faceplate must be installed). If no power is present there, please inspect the circuit breaker in the breaker panel powering the power modules, 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. If power is getting to the power module and there is no 12VDC output to thermostat, the power module will need to be replaced.
