At first, it's perfectly understandable to be slightly perplexed as you attempt to comprehend the functions of your Honeywell thermostat.

But as long as the screen isn’t locked, you can easily adjust the temperatures like a traditional thermostat using the up and down arrows or + and – buttons. 

That said, cycling between the temperature modes, fan settings, and schedule may take some time to get used to, so in this guide, I’ll show you how to carry these out, step-by-step.

What are the Temperature Settings in a Honeywell Thermostat?

For these modern thermostats, complete with a fully-fledged HVAC system, adjusting the temperature is simply not enough, you need to set the temperature mode, adjust the fan settings, and even be mindful of your pre-programmed schedule. 

Getting to know these functions can be a little off-putting, but after you understand the basics, you can simply automate the entire system or manually adjust it whenever you need.

So for Honeywell thermostats, the temperature settings involve:

  1. Adjusting the temperature setpoint
  2. Switching the temperature mode
  3. Adjusting fan settings
  4. Programming/editing the schedule

Adjusting the Temperature

Changing the temperature is one of the most crucial functions of a thermostat. So even if the pre-programmed schedule might seem to get in the way, you can always override the schedule and allow the thermostat to run at your desired temperature.

To change the temperature, use the up or down arrows or + or – buttons on your thermostat model until it shows your desired setting. 

The thermostat display will indicate your desired temperature setpoint and the current ambient temperature, after which, it will start making the changes necessary to reach your setpoint. 

Also, you can change the temperature using mobile apps or even through voice commands.

Adjusting Temperature Modes

To optimize comfort and energy usage, it's essential to know how to switch between heating and cooling on your Honeywell thermostat.

The temperature mode setting allows you to seamlessly go between your AC, heat pump, and auxiliary heating systems depending on your needs.

For instance, if you want a cooler environment, set the thermostat to cooling mode and lower the temperature.

The AC will activate and maintain operation until the desired temperature is achieved.

Conversely, if you require warmth, switch to heating mode, and the thermostat will deactivate the AC and engage the heat pump or furnace.

Keep in mind that available temperature modes may differ based on your specific system and thermostat model.

Generally, you can expect your thermostat to support the following modes: 

  • Heat: Manages the heating system.
  • Cool: Operates the cooling system.
  • Off: Deactivates the heating and cooling systems.
  • Auto: Allows the thermostat to automatically switch between heating or cooling to achieve and maintain your desired temperature.
  • Em Heat: Handles the emergency heat system.

To cycle between these temperature modes, you can either

  1. Access the settings menu and select your preferred mode.
  2. Repeatedly press the “Mode” button or touch prompt until you see the desired setting pop up.
  3. Use your thermostat's dedicated temperature mode toggle slider.

Adjusting Fan Settings

The fan setting in your Honeywell thermostat is another crucial component for optimizing comfort and energy efficiency.

For the fan settings, you have two primary options: “Auto” and “On,” with some models also offering a “Circ” (for circulation) setting.

  • In “Auto” mode, the thermostat activates the fan until the set temperature is reached, then cycles on and off to maintain that level. This mode offers the best energy efficiency for most users.
  • When set to “On,” the fan operates continuously, regardless of temperature levels. While some may prefer constant air circulation, this setting will consume more energy and can often interfere with the AC's ability to draw out humidity.
  • For models with a “Circ” option, the fan turns on for approximately 20 minutes every hour, providing occasional air movement without a significant impact on energy usage.

To adjust your fan setting, simply follow the same process used for changing the temperature mode.

What's the Schedule in a Honeywell Thermostat

When it comes to programmable thermostats, you can command the thermostat to run different temperatures, temperature modes, and fan settings according to a predetermined routine. 

This automated routine, called a “Schedule” is a valuable enhancement as it helps automate your home’s comfort and energy efficiency.

For example, you can schedule the thermostat to power down the HVAC equipment when nobody’s at the house and make it reach a comfortable temperature as soon as you arrive. 

The Default Schedule and Available Options

Different thermostat models vary in the extent of their scheduling options, with modern smart devices offering greater flexibility, especially with features such as geofencing and smart response

By default, your thermostat comes with a pre-set schedule, which may suffice for general scenarios, but spending a few moments to adjust it to your specific needs can make a world of difference.

Don't forget, you can always override the schedule and revert to manual settings whenever you want.

Keep in mind, programming schedules can be tricky on some models, but we've got you covered with model-specific instructions in the sections that follow.

How to Adjust a Honeywell Thermostat: Model-Specific Guides

So with a basic understanding of Honeywell’s functionality, let’s dive deeper into the model-specific instructions on how to adjust temperature settings and program the schedules. 

We’ve managed to cover most of the popular models, but if you don’t find your specific one, feel free to drop us a comment or check our collated list of Honeywell user guides here
