Part 2 Remove Old Thermostat and
Install New Thermostat
Do not disconnect wires from the old thermostat until you
label all the wires according to this manual.
2.1.1After turning off power to your heating & cooling system,
expose wallplate with wires and wire terminals. The required
steps vary depending on your old thermostat type.
2.1 Expose wires connected to
old thermostat
✔The Cover: This usually pulls off, but is sometimes secured by a
screw which must be loosened.
✔The Base: This either pulls off or needs to be removed by loosening
screws under the cover.
✔The Wallplate: This is removed by loosening the screws that hold
the thermostat to the wall.
Your old thermostat may consist of:
• 3 parts: a cover, base and wallplate
or
• 2 parts: a cover and wallplate

✔ Ignore wire colors. There is no standard color code for
thermostat wires.
✔ Ignore existing wire labels, if they are present.
✔ Use the provided labels to label/re-label the thermostat wires.
✔ The new labels must remain on the wires at least until the
installation process is complete.
✔ No two wires can have the same label.
2.2.1 Note you may see two types of wiring in the old thermostat:
1. Wires leading from the wall to a
terminal on the thermostat
2. Wires connecting one terminal to
another (jumper wire).
These don’t have to be labeled.
2.2 Label and disconnect the wires

and identified by this letter…
…Then label its wire with
this letter:
You’ll need this information further in the installation process!
2.2.2 Label each wire that comes out of the wall and attaches to
terminals on the old thermostat. Use labels provided with your
new thermostat.
1. Note the letter printed near each wired terminal
2. For each out-of-the-wall wire:
– find its terminal letter(s) in the left column of the table
on page 9,
– label the wire according to the right column of the table.
3. Make the following notes in the right column of the table
on page 9:
– Circle all your out-of-the-wall
labeled wires
– Pencil in any jumper wire
connecting 2 terminals
Mislabeling the wires could result in damage to your
heating and cooling unit.
Contact White-Rodgers™Customer Service at 1-877-654-9394 if your
old thermostat contains any wired terminals not listed in the table.
Note: No thermostat installation uses all of the wires shown
on page 9. In most cases, between 4 and 5 terminals are wired.

Examples
2.2.3 After labeling all the wires, use a screwdriver to disconnect
each wire from its terminal. Remove the old thermostat.

the old thermostat. You may choose to
tape them to the wall or tightly wind them
around a pencil or screwdriver.

2.4 Match and connect wires
2.4.1 Match each wire coming from the wall to its corresponding
terminal, as shown in the illustration below. Insert each wire into
the hole on the side of its matching terminal. Using a screwdriver,
tighten the screw securely. DO NOT REMOVE THE WIRE LABELS.
A maximum of one wire from the wall can be wired
into each terminal.
No thermostat installation uses all of the wires shown below.
In most cases, between 4 and 5 terminals are wired. The remaining
terminals will not be used.
2.4.2 In the new thermostat, a jumper wire
connects the RC and RH terminals.
If, in your OLD thermostat… Then…
Terminals RC and RH (or 5, or R5) …leave the jumper wire in place
were connected by a jumper wire, in the new thermostat.
There was a terminal R, which you then …leave the jumper wire in place
labeled RC according to 2.2.2, in the new thermostat.
Terminals RC and RH (or 5 or R5) …remove the jumper wire from the

Do not allow wires to touch each other or parts on
the thermostat. Doing so could result in damage to your heating and
cooling unit.
2.3.3 Move the wallplate aside. Drill the mounting holes using a 3/16"
drill bit. With a hammer, tap the wall anchors, provided in the
package, into the drilled holes.
