The thermostat that installs where there is no C-wire. It runs on 24 VAC or on four AA batteries, which removes the single most common reason a smart thermostat job stalls at the wall.
Built for the installer
Automatic wire detection and configuration is the other half of that. Rather than identifying the existing wiring, working out the system type and configuring it manually, the thermostat detects what is connected and sets itself up. On an unfamiliar HVAC system that turns a careful job into a quick one, and it removes a category of miswiring.
It supports Z-Wave Long Range alongside SmartStart and S2. Long Range matters in larger properties and outbuildings where a standard Z-Wave mesh struggles to reach without repeaters.
