Setup
1. Compatibility Check
Before installation, verify your home's HVAC system compatibility. This thermostat is designed for low-voltage systems. It is compatible with forced air (gas, oil, or electric), hot water and steam, and heat pumps with electric backup. It is not compatible with electric baseboard heat (120-240V).

A C-Wire is required for continuous power. If your existing thermostat wiring does not include a C-Wire, an included power adapter can be used as an easy-to-install, low-voltage alternative.
