Are you thinking about installing a thermostat but you do not know how to install Honeywell non programmable thermostat?
You don’t need to worry since this piece will help you out.
The installation process is not complicated. Please read on to understand how you can go about it.
To install your Honeywell non-programmable thermostat, you need to remove the old thermostat first. Check the wires, mark them and take a photo. Insert the wires into the UWP via the backside and into the corresponding terminals.
Insert the wall anchors, mount the UWP, then insert the batteries and mount up the thermostat.
Remove the Old Thermostat
Before you install your new non-programmable Honeywell thermostat, you must remove the old thermostat. Here is a step-by-step guide about how you should remove it.
Step #1: Turn off the Power
Do not begin any process on your electric system when the power is on. You will protect your system and yourself from any electrical shocks.
Click off the switch at the breaker box, or the one you will find on the heating or cooling system.
Ensure that the system is completely off by adjusting the temperature to higher or lower than the room temperature.
If the system does not click within a few minutes, you will know that it is off.
Step #2: Remove the Faceplate
Hold the faceplate, then pull it gently to remove it. If the thermostat has screws, kindly unscrew them, then remove the faceplate.
Kindly do not remove any wire at this point. Check if the system has 120V or 240 wires
Your thermostat will not work if:
- There are thick dark wires with wire nuts in the system.
- Your thermostat has more than 120 volts.
These two conditions show that you have a line voltage system; hence your thermostat will fail to work.
Step #3: Take a Photo of the Wiring
Use masking tape to label each terminal. Ensure you include letters to show where you will insert each specific wire.
If your terminals have the same color or are faded, check the package for the labels given and use them to name the wires.
Please take note of the R-wires you have and include their color. You do not need to include jumpers since your thermostat does not need them.
Ensure that you have checked every other wire in the system and record them. Do not forget their colors too.
The most common terminals include the ones below and their meanings:
- Y – compressor contactor
- C – common wire
- G – fan relay
- O/B – heat pump change over valve powered on cooling/heating
- A or L/A – heat pump fault input
- W2/AUX – auxiliary heat relay
- W – Heat load
- K – wire saver module
- E – emergency heat relay
Points to Note:
Your thermostat still needs batteries since the C terminal does not power the thermostat.
If your old thermostat had K, then it had a wire saver. You will need to rewire so that the new system can use G and Y.
Your non-programmable Honeywell thermostat will not support S, L/A, or U terminals.
Probably all terminals are not on the list. You will need to add other wires that will be necessary to the system.
Step #4: Disconnect the wires
Using your supplied thermostat screwdriver, release the wires from their respective terminals.
Label each wire as you disconnect them. Also, label each corresponding terminal.
Your wires might fall back to the wall. You can prevent this by rolling them on a small tool like a pencil.
How to Install Honeywell Non-Programmable Thermostat
Now you are through with removing your old thermostat. You are now free to install the new Honeywell non-programmable thermostat.
Let us see how you can go about it.
Step #1: Insert the Wires
Bundle the wires, then pull the UWP and insert them via the UWP’s back.
Ensure you leave at least a quarter-inch of the wires exposed to help you insert the wires into their terminals easily.
Step #2: Inserting the Wall Anchors
Your new thermostat comes with wall anchors. Kindly use them to mount the thermostat.
Using the WUP can help you mark the place you would wish to place your wall anchors.
You will need to level the wall plate then use a pencil to mark where you will place those wall anchors.
Drill the holes, then insert the anchors. Ensure that they flush with the wall.
Tip: To make work easier, use a 7/32 drill bit.
Step #3: Set R Switch Location
Check your notes above about the R-switch, then set it up or down.
Use the inner holes to insert the wires into the UWP. Once you insert the wires, the tabs will stay down.
Step #4: Connect the Remaining Wires
Squeeze the tabs as you insert the wires into the corresponding inner holes of the UWP terminals.
Ensure that you insert one wire in one terminal. They should be firm in the place. Tug the wires gently to ensure they are not loose.
You can release the wire anytime you wish by pushing down the terminal tab.
Check the photo you took in the above step again to ensure that each wire color matches the corresponding terminal.
Step #5: Mount UWP
Use the supplied screws to mount up the UWP.
Ensure you use all three screws to mount it securely. When you are through, close the door.
Step #6: Install the Batteries
You will find the battery space at the back of your thermostat; kindly insert them.
Step #7: Attach the Thermostat
Align your thermostat on the UWP and pin it into place safely.
Step #8: Power on the Thermostat
Flip on the breaker or tap the switch on the heating or cooling system to power on your thermostat. You are through with the installation.
Set the Thermostat
Now you are through with installing your thermostat. It cannot just begin to operate unless you set it up.
Here is how you will do the setup.
- Click edit to change the thermostat’s values. You can also select from the available values.
- Click next to save the values.
- Advance to the system setup number.
- Repeat the process until you set all system options.
- Press Done once you are through.
Your thermostat will save the changes you have made and then take you back to the home screen.
How to Install Honeywell Non Programmable Thermostat with Only 2 Wires
The above steps provide you with guidelines on how to install all non-programmable thermostats.
However, there are some non-programmable thermostats with only two wires. How can you install them?
Step #1: Remove your old thermostat control panel.
Step #2: Take a photo of the wiring system. The red wire will always enter R, and the white wire will enter W1 or Rh.
Step #3: Use your screwdriver to unscrew the wires from their corresponding terminals.
Step #4: Remove the faceplate of your old 2-wire Honeywell thermostat and replace it with your new 2-wire Honeywell thermostat.
Step #5: Connect the white and red wires to their respective places. Screw them, then return the control panel.
Turn on the furnace to see if it works. A correct connection of both wires should get your thermostat running.
You can install your Honeywell non-programmable thermostat after removing your old thermostat. Ensure you label the wires and the terminals.
Insert the labeled wires into the UWP, followed by the anchors. Ensure that the wires match their corresponding terminals, then mount your thermostat in place.
