Why Choose a Low Voltage Smart Thermostat with C-Wire Adapter?

A C-wire (common wire) is essential for powering most modern smart thermostats. If your current setup doesn’t have a C-wire, installation can be tricky—unless your new thermostat includes a C-wire adapter. This ensures compatibility and a hassle-free setup, even in older homes.
“Don’t have a C-wire? We’ve included a C-wire adapter in the box.”
