Hello, Rick! I will walk you through a few simple steps to check your home's compatibility with Amazon Smart Thermostat. Here's what to expect: You will be removing your thermostat's faceplate. In most cases this does not require tools. We recommend shutting off power to your thermostat before getting started. First, carefully remove your old thermostat's faceplate. Some faceplates come off when you pull gently on them. Others are held in with clips or screws. Check your old thermostat for high voltage wiring. Look for: Warning labels that say 110v/220v. Wires labeled L1 or L2. Wires with stranded ends. Wires connected by wire nuts. If you see any of these things, Amazon Smart Thermostat won't work with your wiring. When setting up the Amazon Thermostat, it will walk you through how to install. Hope this helps and have a great day.
Sorry, there was a problem. Please try again later.Amazon Smart Thermostat is compatible with most 24V HVAC systems (like conventional force air, heat pump, radiant boilers, etc). . Smart Thermostats require a C-wire (most homes have one) or a C-wire adapter kit (sold separately).
