Electrical shock or equipment damage is possible. Before starting the installation, turn off the power.

During testing, compressor protection is turned off. Avoid cycling the compressor too fast to avoid causing harm to the equipment.

Removing your old thermostat

  1. Switch off power
    Turn off the electricity at the breaker box or switch that controls your heating and cooling equipment to protect it.
    Please keep in mind that turning off the thermostat does not cut off the electricity to the device.
  2. Make sure your system is turned off.
    Change the temperature on your old thermostat to start heating or cooling your system.
    If you haven't heard or felt the system switch on within 5 minutes, the power has been turned off.
    If you have a digital thermostat with a blank display, you may skip this step.
  3. Remove the old thermostat from the wall plate.
    On most thermostats, you may remove the thermostat by lightly gripping and pushing. Screws, buttons, or clasps may be found on certain thermostats.
    At this time, do not disconnect any connections from your thermostat!
  4. Do you have a line voltage system?
    Line voltage systems have thick black wires with wire nuts or are labeled high voltage (120V or higher).
    if YES, your system is not work with this thermostat.
    if No, Continue to the next step
  5. Take photo of your old wallplate's wiring
    You may need to reference this photo later
  6. Remove any jumpers
    A jumper is used to connect two terminals. keep the jumpers with your old wallplate
  7. Label the wires
    Label each wire on your old wall plate with the labels that came with your new thermostat.
  8. Make a note of the wire colors.
    Check the boxes and make a note of the color of the wires connecting to the terminals coming from the wall. Please check all that apply (not all will apply).
  9. Disconnect the cables and remove existing wall plate.
    To remove wires from terminals, you may need to use a screwdriver. Wrap the wires around a pencil to keep them from falling through the wall.
  10. Do you have a C-Wire?
    Examine the thermostat wiring checklist from Step 8, as well as the snapshot you took. Is the C-Terminal fully implemented?
    if YES, this means you not need to install the included C-wire adapter. Skip to Installing your New Thermostat
    If NO, This means you don't have a C-wire connected to your thermostat. Continue next step
  11. Do you have a distribution panel?
    You have distribution panel if you have multiple thermostats and one furnace or heating system
    if YES, C-wire Adapter installation is more complicated on zoned systems, you need a Pro installer in your area
    if NO, continue to the next step
  12. Do you have an unused wire cable?
    See at the bundle of wires coming from the wall
    YES, proceed to step 13
    NO, open the included C-Wire Adapter box and follow the instruction guide
  13. Label unused Wire
    Label your unused wire with the provided "C" sticker label. You may need to use a wire stripper to expose at least 1/4 inch of the wire
  14. Remove the furnace or heating system's lid.
    To access the control board, remove the cover from the heating and cooling system. The terminal labels should be the same as those on your thermostat.
  15. Find the other end of the unused wire
    Locate the wire bundle that is the same as the one at your thermostat.
    The unused wire should be the same color as the wire near your current thermostat. The color you typed down can be found in Step 13.
  16. Connect the unused wire to the C-terminal
  17. Close the cover to the furnace or heating system

Installing Your new Thermostat

  1. Position wall plate
    Open the wall plate that came with your new thermostat. Pass the wire bundle through the rear of the wall plate.
    Make sure that at least 1/4-inch of each wire is exposed to allow for simple insertion into the wire terminals.
  2. Install the necessary wall anchors.
    It is advised that you attach your thermostat using the wall anchors provided in the package.
    The wall plate can be used to designate the location of the wall anchors.
    • Level the wall plate;
    • Using a pencil, mark the placement of the wall anchors.
    • Take off the wall plate;
    • Drill anchor holes
      Drill 7/32" holes if your packaging has red anchors.
      Drill 3/16" holes in your package if it has yellow anchors.
    • Attach the wall anchors.
    • Check that the anchors are level with the wall.
    • Reposition the wall plate.
  3. Determine the proper R-Switch position and insert the appropriate R-wire or wires.
    Set the R-switch to the up or down position based on your wiring notes from Step 8. Wires should be inserted into the inner holes of the terminals on the wall plate. Once the wire is placed, the tabs will remain in place.
    If you have 2 R-Wires (R, RC, RH):
    1. Set right R-Switch to the down position
    2. Insert your RC wire into Rc-terminal
    3. Insert your R or RH wire into R-terminal
    if you have 1 R-Wire (R, RC, RH):
    1. Ensure the right R-switch is in the up position
    2. Insert your R-Wire (R, RH, or RC) into R-terminal
  4. Connect remaining wires
    Push down on the tabs to securely insert the wires into the inner holes of their respective terminals on the wall plate (one wire per terminal).
    To ensure that the wires are tight, gently tug on them.
    If you need to release the wires again, press down the terminal tabs on the wall plate's sides.
  5. Close the door and mount the wall plate
  6. Install your thermostat
    Align the thermostat on the wall plate and firmly snap into place
  7. Turn on the power
  8. Complete setup on the thermostat
    Remove the protective film and check to see whether your thermostat says "Welcome."
