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 the Mysa thermostat is unresponsive to touch and/or commands, there are a few things you can check:

  • Make sure the protective plastic film has been removed from the thermostat, as this could interfere with the thermostat's ability to detect touch.
  • If that didn't work, try a power cycle - turn the breaker connected to the thermostat off and then back on again.
  • The last thing you can do is to make sure the ground wire is securely fastened to the ground screw in the gang box because this can sometimes cause the touch buttons to not function properly.

The ground wire in the floor mat must be connected directly to the ground wire of the supply or to the house ground wire.
