Don't panic if a “Return” message appears on your Honeywell Thermostat. This is completely normal and crucial for the correct functioning of the apparatus. It serves as an integral part of the device's primary attributes.

The “Return” message blinks when it’s working in advance to reach set temperatures assigned to the “Return” or “Home” period in your schedule.

You can let it be, or adjust your schedule to remove it. Simply follow the guide I’ve created below.

What Does the Flashing “Return” Mean?

According to the default schedule in Honeywell Thermostats, there’s a “Leave/Away” period which acts as a “low-power” mode when nobody is at home.

To save power, the temperature setpoint at this period is not comfortable for users. So just before the next period, which is “Return” or “Home,” the thermostat powers the HVAC system so it reaches a comfortable temperature.  

During this short period, the “Return” message on your thermostat might start blinking. Essentially, it’s not an error message but an alert that indicates that the system is working in advance.

This helps set up a comfortable temperature for when you return. 

Pre-Programmed Schedules

The flashing “Return” message will only show up when your thermostat is following a pre-programmed schedule. 

For the majority of the smart and programmable models, these schedules include four distinct periods: Wake, Leave, Return, and Sleep.

Besides that, Honeywell thermostats have a default schedule designed to cater to most homeowners’ daily schedules and temperature preferences.

This default schedule is shown below:

As you can see in the graphic above, the Return/Home period is set to 6.00 P.M. the time when most homeowners return after work. Also, the “Away” temperatures are decreased/increased to minimize power consumption by your AC or Heat Pump/furnace.  

Customizing Your Schedule

However, this pre-set schedule doesn’t always have to be the norm. You can personalize each of these periods as you see fit. 

For instance, you could set your preferred Wake temperature and time earlier or later, depending on when you naturally rise in the morning.

Similarly, you might adjust the Leave, Return, and Sleep settings based on your daily routines.

Programmable Schedule Modes

As I mentioned previously, not all models have this feature. Different models, especially the non-smart programmable ones, have certain limitations depending on the programmable days of the week.

There are four such schedule modes, these are:

  • 1-Week Programming: Set a consistent temperature schedule that’s common for every day of the week, ideal for users who work at home or tend to follow the same schedule every day.
  • 5 + 2 Programming: Customize separate schedules for weekdays and weekends, perfect for those who want different settings when they’re at home during the weekend.
  • 5 + 1 + 1 Programming: Additional personalization by having individualized settings for weekdays, Saturdays, and Sundays. Ideal for users with variable weekend schedules.
  • 7-Day Programming: Gain complete control over your thermostat by setting unique temperature schedules for each day of the week, ideal for users with constantly changing routines.

How to Program the Return Schedule on a Honeywell Thermostat

So, if you’re worried about the default schedule, or prefer to switch things up, this guide will show you how. 

Below, I’ve covered the most popular models with detailed instructions. As such, you’re sure to find a scheduled programming guide that falls in line with your model below.

Via the Honeywell Home App

  • Schedule Mode: Options between 1-Week, 5+2, and 7-day programming. Relabeled as “Grouped Days,” “Schedule” and “Single Days.” 

Before we head into the models, let me walk you through how to set up time-based schedules via the Honeywell Home app. 

  1. First, make sure you have the app downloaded and paired with your Honeywell Smart thermostat.
  2. After that’s all square, open the app and pick your thermostat.
  3. Then, from the thermostat home screen (on the app) tap on the calendar icon at the bottom right (labeled Schedule)
  4. From there, you can choose whether to create schedules for grouped days, single days, or a combination of weekdays and weekends.
  5. To edit a particular time period (Wake, Away, Home, or Sleep), follow the appropriate path for your chosen schedule type.
  6. Then modify settings such as “Time,” “Priority,” “Temperature,” and “Fan” to suit your preferences.

“Time” allows you to set the beginning and end times of each period, while “Priority” lets you select which sensors to activate during that time.

Adjust “Temperature” to control heat and cool setpoints, and “Fan” to assign the fan/blower function (on, auto, or circulate) for that period.

On top of that, you can set up geofencing, sensor-based, or smart features in your scheduling process.

These are handy and efficient but can be sometimes overwhelming and you always need to set them up via the Honeywell app.

RTH221 Series

Programmable Thermostat

RTH221
  • Schedule Mode: 1-Week

The RTH221 Series and older models usually include 1-Week programming. As such, you can only set up a single schedule for every day. There’s no distinction between weekends and weekdays.

  1. To begin programming, press the “SET” button until “Set Schedule” appears on the display.
  2. You can now set your “Wake” time (for Monday to Sunday) by pressing the up or down arrows to select the desired hour and minute.
  3. After setting the time, press “SET” once more and use the arrow keys to determine the corresponding temperature for this period.
  4. Next, follow the same steps (2 and 3) for each subsequent time period, such as “Leave,” which denotes the time when you're away from home and may prefer a different temperature.
  5. After completing these adjustments for all time periods, press the “RUN” button to save your schedule and exit the settings mode.

Also, don’t forget to set it to the correct system (Heat or Cool) before making any adjustments, as the programming will not be accurate if the wrong mode is selected.

Wrapping Up

The return mode starts flashing whenever the thermostat is prepared in advance for the “Return” or “Home” schedule periods. Honeywell Thermostats have a default schedule but you can also customize them.

That said, the amount of flexibility offered in programming the schedule may vary so make sure to read up on the guide above and customize via the app, if possible.
