You may have a Honeywell digital thermostat if you have a programmable thermostat then you already know how to program Honeywell thermostat. If not then you need to know how to program Honeywell Thermostat in very easy seps. Honeywell is one of the leading producers of thermostats, offering dozens of different models, ranging from simple styles, which allow you to program the temperature for a single day every week, to complex touch-screen models that let you program temperature adjustments for different days of the week.

Some advantages of honeywell thermostat

Honeywell thermostats are a popular choice for homeowners looking to upgrade their heating and cooling systems. Some of the most notable benefits of Honeywell thermostats include the following:

  • Remote Control: Many Honeywell thermostats can be controlled from your smartphone or tablet, so you can adjust the temperature even when you’re away from home.
  • Programmable Features: Honeywell thermostats come with a range of programmable features, so you can adjust your heating and cooling system automatically based on your schedule.
  • User-Friendly Design: With their simple, intuitive interfaces, Honeywell thermostats are easy to use and program, even for those who need to be tech-savvy.
  • Compatibility: Honeywell thermostats are compatible with a wide range of heating and cooling systems, so you can use them no matter what type of system you have in your home.

How to identify programmable thermostats?

Most people are now aware of the advantages of programmable thermostats. By automating the process of turning down the thermostat at night or when you’re away from home, you can save 10 to 30 percent on energy costs. In this guide, you will learn how to program Honeywell thermostat in detail.

How to identify programmable thermostats?

Although a great many (or perhaps most) Honeywell thermostats are now digitally programmable models, there are still simpler models that allow you to set and raise temperatures manually. It’s easier to find the right thermostat for your home because there are many options, but determining if yours is a programmable model isn’t always straightforward. It is often evident from the presence of a “Prog” or “Set” key that a Honeywell thermostat is programmable. These buttons are missing from those that aren’t programmable, so they have nothing to set. A typical non-programmable thermostat on the left and a programmable thermostat on the right.

You may find that some of the latest models do not have any buttons but instead feature a touch-screen interface that displays the “set” command directly on the screen. Listed below are some of the most popular Honeywell thermostat models. This list is not comprehensive, but it does demonstrate the variety of options available. The thermostat in your house probably has something to do with one of these things:

  • The Programmable Thermostat Models

How to program Honeywell thermostat?

How to program Honeywell thermostat? With so many thermostat styles, it’s impossible to describe the programming process for every single one. All thermostats, however, follow pretty much the exact directions, so it shouldn’t be too difficult to interpret the following instructions, even if you don’t have the same model. here are instructions on how to program Honeywell thermostat. Programming this Honeywell 5-1-1 thermostat is based on the Honeywell RTH6450D1009. The programming process is similar to that of many other Honeywell thermostats, if not identical.

Step 1: The time is set

The time of day will appear on the screen as soon as the SET button is pushed. You can then adjust the time by using the arrow buttons to show the correct time of day. By pressing the DONE button, the time will be locked in.

Step 2: First, set the program.

  • Once you have pressed the SET key, press the key labeled “SET SCHEDULE.” (On some thermostats, you must repeatedly press the SET key to toggle between the various functions.
  • You can switch to the MON-FRIDAY WAKE display by pressing both the UP and DOWN arrow keys while the display flashes; then click next.
  • To set the time you typically wake up during the Monday to Friday workweek, use the UP and DOWN arrow keys. Press NEXT once you have set the appropriate time.
  • You can now set the temperature you desire for that weekday wake-up time by using the UP and DOWN arrow keys. To lock in the correct temperature and move on to the following period, press NEXT after seeing the proper temperature.
  • Lock in the following times, then temperatures, for the subsequent periods of the program: Leave, Return, and Sleep, by using the UP and DOWN arrow keys and the NEXT button. Most programmable thermostats provide this four-temperature program as standard.

Step 3: Start the following program

Pressing the NEXT key after locking the last temperature period for Monday through Friday will activate the following program available on your thermostat. The next program is Saturday on our thermostat.  Then program this in the same manner (see step 2), and repeat until all programs are set. A 5-2 thermostat may only have one additional program. A 7-day thermostat may have as many as six different programs.

Step 4: Finalizing the Program and Making Adjustments

The setup menu is closed by pressing the DONE button, and the program is locked. A simple process can be followed if you made an error in the initial programming or if your schedule changes and you need to adjust the program: After clicking the SET SCHEDULE button, use the NEXT key and the UP/DOWN arrow key to move through the menu options and change the settings. As an example, let’s say you want to adjust the waking time and the temperature simultaneously.

Step 5: Programming override

If you are at home from work one day, but you do not want the thermostat program to drop the temperature to 60 degrees, for instance? The desired temperature will be displayed on your screen when you press the arrow keys. If your thermostat displays the word “TEMPORARY” on the screen, the system will hold the temperature at that setting until your schedule changes, and you take back control of your system. You can resume the program by hitting the RUN SCHEDULE button when you are ready.

What to Do When a Honeywell Thermostat’s Batteries Run Low

If your device does need batteries, changing them is simple. Do not panic if your screen seems dim or black until the batteries change.

  1. Take off the thermostat’s faceplate. Most thermostats may be easily removed with consistent, intense pressure. On the top and bottom of some models, there are little tabs. If your model has charged, you should be able to tell with a quick visual check.
  2. Discard the outdated batteries. Your particular model may require AA or AAA batteries. Check the batteries you are changing to ensure they are the correct size.
  3. Put the fresh batteries inside the battery compartment.
  4. Reinstall the faceplate on the backplate. The thermostat display should turn back on after it is reconnected. Depending on your Honeywell model, select the Menu or Program key to check that any previously programmed settings are still accurately preserved.


Why does the Honeywell thermostat not follow the schedule?

The thermostat has an adaptive recovery feature that learns how long it takes to reach a set point to start heating or cooling earlier than the scheduled start time. Refer to the User Guide to access the Installer Setup to disable this feature.

Is the Honeywell thermostat constantly changing temperature?

You may need to program the temperature. If you adjust the temperature manually, the change will only last until the following program. The standard default cooling program is 85 degrees.

Are Honeywell thermostats resettable?

With the Honeywell T5, T5+, and T6 series thermostats, you can easily reset them using quick access. Just hold the MENU button and select RESET from the menu. Your Honeywell T5, T5+, or T6 thermostat will now be reset.
