How many stages and accessories does your system have?
Match the manufacturer's published stage list and accessory terminals to your equipment. A listed system type is a compatibility statement, not a tested installation guarantee for your wiring.

What this catalogue covers
Wi-Fi connected 24 V low-voltage thermostats sold new in the US. Line-voltage thermostats, pro-only equipment interface modules, utility-program packages and measured energy savings are outside this catalogue.
Specifications come from the linked manufacturer documents and seller listings. We have not independently tested these products.
Before you choose.
Do you have a C wire, and what does the box include?
Some packages include a power extender or rely on battery and power-sharing designs; others require a C wire outright. The included parts differ between packages of the same model.
Which app, account and platforms will you use?
Setup normally requires the maker's app and account. Native HomeKit, Alexa or Google support and Matter certification are separate claims; check the one you need.
