  • REQUIRED: A C-Wire (common wire) is needed for 24 VAC power. If you do not have a C-Wire, then a C-Wire Adapter is provided.
    This guide will help you determine if you have a C-Wire or will need to use the included C-Wire Adapter (Step 10). The C-Wire is a wire that originates from your heating and cooling system and needs to be connected to the C terminal on your thermostat. There is no universal color used to designate this type of wire.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - designate this type
  • Compatible with most heating/cooling, and heat pump systems
  • Does not work with electric baseboard heat (120-240V)
  • Does not work with millivolt systems
  • Does not support S terminals for indoor and outdoor sensors
  • Android or iOS smartphone, tablet, or device

  1. Turn off power 
    ROUGHNECK 41874 Portable Fuel Transfer Box Kit -warning To protect your equipment, turn off the power at the breaker box or switch that controls you heating and cooling equipment.
    Note: The thermostat off switch will not turn off the power to the equipment.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - Turn off power
  2. Check that your system is off
    Change the temperature on your old thermostat so that your system starts heating or cooling.
    If you don’t hear or feel the system turn on within 5 minutes, the power is off.
    Note: If you have a digital thermostat that has a blank display, skip this step.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - system is off
  3. Remove your existing thermostat from the wall plate
    On most thermostats, you can take off the thermostat by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
    ROUGHNECK 41874 Portable Fuel Transfer Box Kit -warning Do not remove any wires from your thermostat at this time!Honeywell T9 Smart Thermostat RCHT9610WFW2003 - wall plateSONIQ E24FB40A 24 FHD LED LCD TV -WARNING Compatibility Check
  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).
    YES
    Your system is not compatible. Go to honeywellhome.com/contacta-pro to find a pro installer in your area.
    NO
    Continue to the next step.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - voltage system

    You may need to reference this image later.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - existing wall
  6. Remove any jumpers
    A jumper is used to connect two terminals. It may look like a small staple or a colored wire.
    Do not discard.
    Keep jumpers with your old wall plate.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - Remove any jumpers
  7. Label the wires
    Use the stickers provided with your new thermostat to label each wire on your existing wall plate.
    Do not label jumpers. Your new thermostat does not need jumpers.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - Label the wires
  8. Write down the colors of the wires
    Check the boxes and write down the color of the wires connected to terminals that are coming from the wall. Check all that apply (not all will apply).Honeywell T9 Smart Thermostat RCHT9610WFW2003 - colors of the wires* A C-wire or C-Wire Power Adapter (included) is required.
    ** The T9 Smart thermostat cannot control equipment wired to U1 or U2.
    If there are wires in terminals that are not listed, you will need additional wiring support. Visit HoneywellHome.com/support to find out more.
  9. Disconnect the wires and remove the old wall plate
    You may need a screwdriver to release wires from terminals.
    Tip: Wrap the wires around a pencil to prevent them from falling in the wall.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - Disconnect the wiresSONIQ E24FB40A 24 FHD LED LCD TV -WARNING Compatibility Check
  10. Do you have a C-Wire?
    Look at the thermostat wiring checklist from Step 8, or the photo you took. Is the C-Terminal checked?
    YES
    This means you will not need to install the included C-Wire Adapter. Skip to Installing Your New Thermostat (page 9).
    NO 
    This means you don’t have a C-wire connected to your thermostat. Continue to the next step.Honeywell T9 Smart Thermostat RCHT9610WFW2003 - C-Wire
