We just bought a house with a Comfort II thermostat that controls three zones in the house. Unfortunately, the seller didn't have the owner's manual so it's been a challenge trying to figure out how to run it efficiently. On top that, it's blinking "E2" so I called in the local HVAC technician recommended by Carrier and he doesn't readily know what the blinking code indicates. Any help operating the thermostat and/or figuring out what to do about the message is appreciated. Thanks a million!
