Honeywell thermostats are popular devices that help homeowners control the temperature of their homes. If you’re a first-time user of a Honeywell thermostat, you may be wondering how to set it up. The process is actually quite simple and can be completed in just a few minutes.
Before you start, you’ll need to gather a few things:
- Your Honeywell thermostat
- A screwdriver
- Two AA batteries
Once you have everything you need, you can follow these steps to set up your thermostat:
- Remove the front panel of the thermostat. To do this, simply insert the screwdriver into the small hole on the bottom of the thermostat and gently pry the panel off.
- Insert the batteries into the thermostat. The battery compartment is located on the back of the thermostat. Insert the batteries according to the diagram on the inside of the battery compartment.
- Replace the front panel of the thermostat. Once the batteries are installed, simply snap the front panel back into place.
Your Honeywell thermostat is now set up and ready to use. You can adjust the temperature by using the up and down arrows on the front of the thermostat. You can also use the mode button to switch between heating and cooling modes.
Understanding the Honeywell Thermostat Models
Honeywell is a leading manufacturer of thermostats, offering a wide range of models to suit different needs and budgets. Whether you’re looking for a basic thermostat or an advanced model with smart features, Honeywell has a thermostat to meet your requirements.
Non-Programmable Thermostats
Non-programmable thermostats are the simplest and most affordable type of thermostat. They allow you to set a single temperature that the thermostat will maintain indefinitely. Non-programmable thermostats are ideal for small spaces or for people who don’t need to adjust the temperature frequently.
| Features | Benefits |
|---|---|
| Single temperature setting | Easy to use and understand |
| No programming required | Low cost |
| Limited flexibility | Not suitable for spaces where temperature needs vary |
Locating and Removing the Thermostat
Finding the Thermostat
The thermostat is usually located on a wall in a central area of your home. It may be near the front door, in a hallway, or in a living room. If you can’t find the thermostat, consult your home’s manual or floor plan.
Removing the Thermostat
To remove the thermostat, follow these steps:
- Turn off the power to the thermostat. This can be done by flipping the circuit breaker or removing the fuse that supplies power to the thermostat.
- Locate the screws that hold the thermostat to the wall. There are usually two screws located at the top or bottom of the thermostat.
- Remove the screws.
- Pull the thermostat straight out from the wall.
| **1.** | Turn off the power to the thermostat. |
| **2.** | Locate the screws that hold the thermostat to the wall. These screws are usually located at the top or bottom of the thermostat. |
| **3.** | Remove the screws that hold the thermostat to the wall. |
| **4.** | Pull the thermostat straight out from the wall. |
Once the thermostat is removed, you can proceed to the next step of the installation process.
Installing the New Thermostat
The first step is to remove your old thermostat. To do this, simply turn off the power to your HVAC system at the circuit breaker. Once the power is off, you can remove the faceplate of your old thermostat and disconnect the wires.
Next, you need to mount your new thermostat. The Honeywell RTH9585WF Smart Thermostat comes with a mounting plate that you will need to attach to the wall. Once the mounting plate is in place, you can connect the wires from your old thermostat to the terminals on the new thermostat.
Finally, you need to turn the power back on to your HVAC system and test your new thermostat. To do this, simply adjust the temperature setting on your thermostat and make sure that your HVAC system turns on and off as expected.
Connecting the Wires
The Honeywell RTH9585WF Smart Thermostat uses a standard color-coded wiring system. The following table shows the color of each wire and the terminal on the thermostat that it should be connected to:
| Wire Color | Terminal |
|---|---|
| Red | Rh |
| White | W |
| Green | G |
| Yellow | Y |
| Blue | C |
| Black | O/B |
If you have a different type of thermostat, you may need to refer to the manufacturer’s instructions for the correct wiring diagram.

Using the Programmable Features
Honeywell thermostats offer programmable features that allow you to customize your home’s temperature settings based on your daily routine. Here’s how to set these features:
Once you have entered the programming mode, you will see a list of periods.
These periods represent the different times of day when you want the thermostat to adjust the temperature.
For example, you might have a morning period, an afternoon period, and an evening period.
You need to set the temperature for each period.
You also need to set the time when the period starts and ends.
Once you have set the times and temperatures for all of the periods, your thermostat will automatically adjust the temperature according to your program.
Setting the Temperature for Each Period
To set the temperature for a period, use the up and down buttons to adjust the number. The temperature will be displayed on the thermostat’s screen.
Setting the Start and End Times for Each Period
To set the start and end times for a period, use the up and down buttons to adjust the hour and minute values. The time will be displayed on the thermostat’s screen.
Temporary Override
To temporarily override the programmed schedule, simply adjust the temperature using the up and down buttons. The new temperature will be displayed on the thermostat’s screen. The thermostat will return to the programmed schedule at the next scheduled time.
Holiday Mode
Holiday mode allows you to set a temporary schedule for a specific period of time. This is useful if you are going away on vacation or if you have guests staying over. To set holiday mode, press the “Holiday” button on the thermostat. Then, use the up and down buttons to set the start and end dates for the holiday period. The thermostat will return to the programmed schedule at the end of the holiday period.
Other Programmable Features
Honeywell thermostats offer a variety of other programmable features, such as:
