  • The Nest site has a tool that will tell you if it's compatible with your system. You have to take the cover from your current thermostat and enter the labels of your wires. They have had a few updates since it came out that have added compatibility with more types of equipment.

  • Yes, Nest works with radiant heat. Some floor systems have an additional temp sensor on the floor itself that connects to the thermostats, Nest uses their True Radiant technology to achieve the same result. As such you won't need to connect that sensor wire if you have one. (Normally labeled S)
