Removing your old thermostat

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.
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.
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!

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.
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.
Record which R-wire(s) you have and write down the color of the wire(s).
NOTE: Do not include jumpers as a part of your count. The thermostat does not need jumpers.
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):

**** NOTES:
- C does not power the thermostat display or operations; batteries are always required.
- If K was used on old thermostat you have a C-wire adapter 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 honeywellhome.com/support 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.
Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.

Wires Installing your RTH5160 thermostat

RTH5160 thermostat

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.
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: If your box contains red anchors, use a 7/32” drill bit. If your box contains yellow anchors, use a 3/16” drill bit.
Set R-switch position and insert R-wire(s).
Set the R-switch up or down based on your wiring notes in Step 6
Insert wires into the inner holes of the terminals on the UWP. The tabs will stay down once the wire is inserted.
NOTE: Alternate wiring options are shown on pages 11-12.
If you have 1 R-wire (R, Rh, or Rc)
Set R-switch to the up position.
Insert your R-wire (R, Rh or Rc) into R-terminal.

If you have 2 R-wires (R or Rh, and Rc)
Set R-switch to the down position.
Insert your Rc wire into Rc-terminal
Insert your R or Rh wire into R-Terminal.
Connect remaining wires.

Depress the tabs to put the wires into the inner holes of the 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 a wire again, push down the corresponding terminal tab on the side of the UWP.
NOTE: Alternate wiring options are shown on pages 11-12.
Confirm wiring matches snapshot. Please confirm wiring matches terminals from the photo you took in Step 5.
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.
Install batteries.
Insert two AA alkaline batteries in the back of the thermostat as shown.
Attach your thermostat.
Align the thermostat onto the UWP and firmly snap it into place.
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:

If you must connect both
R and Rc wires, set the
R Slider Tab to the down position (2 wires).
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.
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.
C does not power the thermostat display or operations; batteries are always required.

Wiring—heat pump

Connect wires: heat pump

Match each labeled wire with same letter on new thermostat.
Insert the wires into the matching terminal.
NOTE: If you have difficulty inserting wires, you may have to press down the terminal push button next to the corresponding terminal.
Labels don’t match?
If labels do not match letters on thermostat, see “Alternate wiring (conventional systems)“ above.

Alternate wiring (for heat pumps only)

NOTES:

Keep R Slider Tab in the up position (1 wire).
If your old thermostat had both V and VR wires, stop now and contact a qualified contractor for help.
If your old thermostat had separate O and B wires, attach the B wire to the C terminal. If another wire is attached to the C terminal, stop now and contact a qualified contractor for help.
If your old thermostat had Y1, W1 and W2 wires, stop now and contact a
qualified contractor for help.
C does not power the thermostat display or operations; batteries are always required.
This model doesn’t support the heat pump fault alert (L/A terminal). If this is desired, please contact a contractor for replacement model.

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.

Alerts screen

You will see the alert icon and the alert number on the screen.
Press Next (+) to see additional alerts, if any. Then press Done to go back to the home screen.
NOTE: If the alert is a critical alert, you may not be able to access the home screen and should call a HVAC professional

Alerts codes

Number	A l ert/Reminder	Definition
170	Internal Memory Error	The memory of the thermostat has encountered an

error. Please replace the thermostat.
173| Thermostat Temperature Sensor Error| The sensor of the thermostat has encountered an error. Please replace the thermostat.
405| Low Battery Alert| The batteries are getting low. Replace them within two months.
