    Removing your old thermostatHoneywell-RTH7500-Series-Programmable-Thermostat-figure-9

    • Turn power OFF. To protect yourself and your equipment, turn off the power at the breaker box or switch that controls your heating/cooling system.
    • Check that your system is off. Change the temperature on your old thermostat. If you don’t hear the system turn on within 5 minutes, the power is off.

    If you’re installing other programmable models, check our Honeywell RTH2410 Series Thermostat User Guide.

    Note: If you have a digital thermostat that has a blank display, skip this step.

    •  Remove the old thermostat’s faceplate. On most thermostats, you can take off the faceplate by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps. Do not remove any wires from your thermostat at this time!Honeywell-RTH7500-Series-Programmable-Thermostat-figure-10

    Make sure there are no 120 V/240 V wires.

    Do you have thick black wires with wire nuts?
    Is your thermostat 120 V or higher?
    If you answered yes to either of these questions, you have a line voltage system, and the thermostat will not work.Honeywell-RTH7500-Series-Programmable-Thermostat-figure-11

    If you are unsure, visit: resideo.com

    • Take a picture of how your wiring looks right now. Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your thermostat.

    Tip: If the color of your wires has faded or if 2 terminals have the same wire color, use the wire labels provided in the package to label each wire.

    • Remove any jumpers. A jumper connects one terminal to another terminal. It may look like a small staple or even a colored wire, and it must be removed before continuing. Use a screwdriver to release wires from terminals. The RTH7400/RTH7500 thermostat does not need jumpers.Honeywell-RTH7500-Series-Programmable-Thermostat-figure-13
    • Record if you have wires in the following terminals. Do not include jumpers as part of your count. The thermostat does not need jumpers.Honeywell-RTH7500-Series-Programmable-Thermostat-figure-14
    • Write down the color of the wires. Check the wires that are connected to the terminals. Next to the check mark, write down the color of the wire. Do not include jumpers as part of your count.
      Check all that apply (Not all will apply): The RTH7400/RTH7500 thermostat does not support L/A, S, or U terminals.Honeywell-RTH7500-Series-Programmable-Thermostat-figure-15

    If there are wires in terminals that are not listed, you will need additional
    wiring support. Visit resideo.com to find out if the thermostat will work for you.

    • Disconnect the wires and remove the old wall plate. Use a screwdriver to release wires from terminals. Then, use a wire label to identify each wire as it’s disconnected. The letter on the wire label should match the letter on the terminal.Honeywell-RTH7500-Series-Programmable-Thermostat-figure-16Honeywell-RTH7500-Series-Programmable-Thermostat-figure-17

    Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil

    Smart Response® Technology

    This feature allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the time you set. For example: Set the Wake time to 6 am, and the Honeywell RTH7500 Series Programmable Thermostat temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Recovery” is displayed when the system is activated before a scheduled period.
