How to Reprogram Your Honeywell Thermostat: A Step-By-Step Guide


Honeywell thermostats are known for their reliability and energy-efficient features. If you need to reprogram your Honeywell thermostat, whether it’s due to a change in your schedule or a desire to optimize energy savings, this guide will walk you through the process step by step.

Understanding Your Honeywell Thermostat

Before we dive into reprogramming, let’s understand the basic functions of your Honeywell thermostat:

  1. Set Temperature: This is the temperature to which your thermostat will heat or cool your home.
  2. Mode: Your thermostat has different modes like Heat, Cool, and Auto, allowing you to control your HVAC system’s function.
  3. Fan Setting: This determines when the fan runs – either continuously (On) or only when heating or cooling (Auto).
  4. Programmable Schedule: Many Honeywell thermostats come with a programmable feature, which allows you to set different temperatures for different times of the day.

Reprogramming Your Honeywell Thermostat

Here’s how to reprogram your Honeywell thermostat:

  1. Access the Menu: Depending on your thermostat model, you’ll need to access the programming menu. Typically, this involves pressing the “Menu” button on the thermostat.
  2. Select the Day and Time: Use the up and down arrow buttons to navigate to the day and time you want to reprogram. Press “Select” or “Set” to confirm your choice.
  3. Set the Temperature: Navigate to the desired time block (e.g., “Morning” or “Away”) and use the arrow buttons to adjust the temperature. Confirm your choice.
  4. Repeat for Other Time Blocks: Continue this process for other time blocks you want to program, such as “Day,” “Evening,” and “Night.”
  5. Review and Save: After setting all your time blocks, review your programming to ensure it’s correct. Once you’re satisfied, select “Save” or “Done.”

Tips for Effective Programming

To make the most of your Honeywell thermostat, consider these tips:

  1. Consistent Schedule: Aim for a consistent schedule to optimize energy savings. For example, if you leave for work at 8 AM every day, program your thermostat to lower the temperature around that time.
  2. Utilize Vacation Mode: If your thermostat has a vacation mode, use it when you’re away for an extended period. It will help you save energy during your absence.
  3. Smart Thermostats: Consider upgrading to a smart thermostat. They offer more advanced programming features and remote control via a smartphone app.
  4. Regular Maintenance: Keep your thermostat and HVAC system well-maintained to ensure accurate temperature readings and efficient operation.


Reprogramming your Honeywell thermostat is a straightforward process that allows you to take control of your home’s temperature and energy usage. By setting a well-thought-out schedule, you can enjoy a comfortable living environment while optimizing your energy savings. Remember to consult your thermostat’s user manual for specific instructions related to your model.
