Removing your old thermostat

1. 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.

2. 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.
   Note: If you have a digital thermostat that has a blank display, skip this step.

3. 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!

4. Make sure there are no 120/240V wires.
   Do you have thick black wires with wire nuts? Is your thermostat 120V or higher? If you answered yes to either of these questions, you have a line voltage system and the thermostat will not work. If you are unsure visit: yourhome.honeywell.com/support Wire nut Thick black wire

5. 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.

6. Remove any jumpers.
   A jumper connects one terminal to another terminal. It may look like a small staple or even a colored wire and must be removed before continuing. Use a screwdriver to release wires from terminals. The RTH7500 thermostat does not need jumpers.

7. Record if you have wires in the following terminals.
   Do not include jumpers as a part of your count. The thermostat does not need jumpers.

8. Write down the color of the wires.
   Check mark the wires that are connected to terminals. Next to the check mark, write down the color of the wire. Do not include jumpers as a part of your count. Check all that apply (Not all will apply):
   The RTH7500 thermostat does not support L/A, S, or U terminals. If there are wires in terminals that are not listed, you will need additional wiring support. Visit yourhome.honeywell.com/support to find out if the thermostat will work for you.

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

Installing your RTH7500 thermostat

10 Bundle and insert wires through the UWP.
Pull open the UWP and insert the bundle of wires through the back of the UWP. Make sure at least 1/4-inch of each wire is exposed for easy insertion into the wire terminals.

11 Insert the wall anchors.
It is recommended that you use the wall anchors included in the box to mount your thermostat. You can use the UWP to mark where you want to place the wall anchors.
a) Level the wall plate.
b) Mark the location of the wall anchors using a pencil.
c) Drill the holes. d) Insert wall anchors.
e) Make sure anchors are flush with wall.
Tip: Use a 7/32 drill bit.

12 Set R-switch position and insert R-wire or wires.
Set the R-switch up or down based on your wiring notes in Step Insert wires into the inner holes of the terminals on the UWP. The tabs will stay down once the wire is inserted.

13 Connect wires from Step 8.
Depress the tabs to put the wires into the inner holes of their corresponding terminals on the UWP (one wire per terminal) until it is firmly in place.
Gently tug on the wires to verify they are secure.
Tip: If you need to release the wires again, push down the terminal tabs on the sides of the UWP.

14 Mount the UWP and close the
door. Mount the UWP using the provided screws. Install all three screws for a secure fit on your wall. Close the door after you’re finished.
15 Confirm wiring matches snapshot.
Please confirm wiring matches terminals from the photo you took in Step 5.

16 Install batteries.
Insert two AA alkaline batteries in the back of the thermostat as shown.

17 Attach your thermostat.
Align the thermostat onto the UWP and firmly snap it into place.
18 Turn your power ON.
Turn on the power at the breaker box or switch that controls the heating/ cooling system.

Wiring–conventional systems

Alternate wiring (conventional systems)
If labels do not match terminals, connect wires as shown below (see notes, below). NOTES:

1. If you must connect both R and Rc wires, set the R Slider Tab to the down position (2 wires).
2. If your old thermostat had both R and RH wires, set the R Slider Tab to the down position (2 wires). Then connect the R wire to the Rc terminal, and the RH wire to the R terminal.
3. If your old thermostat had only 1 C or C1 wire, connect it to the C terminal. If your old thermostat had 2 C or C1 wires, wrap each separately with electrical tape and do not connect them.

Wiring–heat pump

Connect wires: heat pump

1. Match each labeled wire with same letter on new thermostat.

Advanced menu

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 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 time period.

Battery replacement

Batteries are required to provide power. Install fresh batteries immediately when the low battery icon appears. The icon appears about two months before the batteries are depleted.
Even if the low battery icon does not appear, you should replace batteries once a year, or before leaving home for more than a month.
If batteries are inserted within two minutes, the time and day will not have to be reset. All other settings are permanently stored in memory, and do not require battery power.
NOTE: When replacing batteries, alkaline batteries are recommended.
