Installation & Product Tips

System Compatibility: This is a 24V low-voltage thermostat compatible with gas furnaces, heat pumps, central air conditioners, and boilers. Verify your system uses 24V control wiring before purchasing.

Heat Pump Systems: If you have a heat pump, ensure you select a thermostat rated for heat pump operation (1 Heat / 1 Cool stages) to properly control the reversing valve.
C-Wire Requirement: Most programmable thermostats require a common (C) wire for continuous power. Check your existing wiring before installation. If no C-wire is present, a C-wire adapter may be needed.

Do I need a C-wire for installation?

Most digital programmable thermostats require a C-wire (common wire) for continuous 24V power. Check your existing thermostat wiring — if you see a wire connected to the "C" terminal, you have a C-wire. If not, a C-wire adapter or power extender kit may be needed.
