Quick Installation Guide
Removing your old thermostat
2 Check that your system is off.
Change the temperature on your
old thermostat to be above room
temperature in heat mode or below
it in cool mode. 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.
1 Turn power OFF.
To protect yourself and your
equipment, turn off the power at
the breaker box or the 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 new
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.

Note: Do not include jumpers as a part of your count. The thermostat does
not need jumpers.

7 Record the remaining wires and 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):

K
NOTES:
• Cdoes not power the thermostat display or operations; batteries are
always required.
• If Kwas used on old thermostat you have a wire-saver at the equipment.
Re-wiring would need to be done so that Y and G are used instead of K.
• The RTH5160 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.

Quick Installation Guide
8 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 RTH5160 thermostat
9 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.

e) Make sure anchors are flush with
wall.
Tip: Use a 7/32 drill bit.
Insert wires into the inner holes of the terminals on the UWP. The tabs will
stay down once the wire is inserted.
