    Remove the old wallplate from the wall after all wires have been labeled and disconnected.Remove wallplate
  5. Separate Wi-Fi thermostat and its wallplate.
    On your new thermostat, grasp the finger holds on the top and bottom of the wallplate with one hand and the thermostat (front) with the other hand. Pull pieces apart.
  6. Mount wallplate for Wi-Fi thermostat.

    If necessary:
    Drill 3/16-in holes for drywall.
    Drill 7/32-in holes for plaster.Mount wallplate for Wi-Fi thermostat

    Note: The Wi-Fi thermostat requires a C wire to operate. The C, or common, wire brings 24 VAC power to the thermostat. Many older mechanical or battery operated thermostats do not require a C wire. If you don’t have a C wire, try:

    • Looking for an unused wire that is pushed into the wall. Connect that wire to C and check that it is connected to the 24 VAC common at your heating/cooling system. Check the video section at wifithermostat.com.
    • Installing a new wire. If required, contact a contractor to install a new wire (go to wifithermostat.com to locate a contractor in your area).

  1. Hello
    We use a HoneyWell air conditioner for the hot and cold air conditioner. This air conditioner is old so there is no Wifi connection, I want to change the one with Wifi connection, which can be adjusted on the iPhone and anywhere. Could you please advise me what kind of change is appropriate and how to install the wiring?
    Thank you very much.
    Chào bạn
    Nhà mình có xử dụng một bộ điều hòa HoneyWell cho máy điều hòa nóng lạnh. Bộ điều hòa này loại củ nên không có kết nối Wifi, mình muốn thay loại có kết nối Wifi, có thể điều chỉnh được trên iPhone và ở bất cứ nơi nào. Bạn có thể vui lòng tư vấn cho mình cần thay loại nào phù hợp và cách cài đặt nối dây ra sao?
    Rất cảm ơn bạn.
