Removing your old thermostat
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.
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.
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.

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.

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.
