Interactive Compatibility Check

The Vine Smart WiFi Thermostat is designed to work with 24VAC heating and cooling systems including traditional Furnace, Heat Pump A/C with Emergency Heating, 1-Heat, 1-Cool, and 1-Heat, 1-Cool, and double stage heating/cooling. It's easy to find the compatibility from an existing connection:

  1. Remove the old thermostat.
  2. Take a look at the wires connected to the wall plate and old thermostat. Take a picture of the old connection for reference.
  3. Use our interactive wiring chart to determine which arrangement is compatible with your home setup.

Vine comes with 7 wire connections and supports:
1-Heat and 1-Cool, or heat pump A/C with emergency and auxiliary heating.

If your Smart WiFi thermostat doesn't turn on after you have correctly connected the wires as illustrated, it may be caused by no power to the "C " terminal from the furnace terminal block. Please consult a professional HVAC technician for help.
