yes, you need 3 units
Sorry, there was a problem. Please try again later.My AC has 2 zones. One upstairs, and one downstairs. I had to have 2 thermostats, but you may be able to use the room sensors to make yourd work. I guess that's a question for the HVAC company.
Sorry, there was a problem. Please try again later.The Nest Learning Thermostat is only able to control the part of a zoned system the current thermostat in place controls. So if you have 3 zone's in the home all with their own individual thermostats. The Nest would control which ever zone it's wired to.
