This is our Honeywell Thermostat Pictures Gallery, of photos and screenshots we’ve taken with the various thermostat models we’ve owned through the decades.
Various Thermostat Settings
Locking and Unlocking the Thermostat
Control how the t-stat locks and unlocks on the Security Settings screen, shown next.
The Change Lock Mode page gives options for unlocking and locking the t-stat.
Next, you can set a PIN that you later use to unlock a locked t-stat.
Next, you see the next screen when you’ve successfully set up a new passcode on the t-stat.
Moreover, the Change Lock Mode screen shows that the t-stat is UNlocked.
Setting Time and Date
Now on the next screen you have three options: Set Time, Set Date, and Previous Menu.

How to Set the Date
How to Set the Time
Additionally, on the Please Set The Time screen, you can set the hour, minute, and AM / PM values. But once you register the t-stat, it sets the time from the internet automatically. So you’ll rarely have to set the date and time by hand.
The t-stat also shows this amber message when it is currently not registered with the Honeywell Total Connect Comfort system.
Note that some of the menus in this model have a HOME button, that you can tap to quickly get back to the Home screen.
Then there are some menus, that allow you to return to the Previous Menu. In these, to get back to the HOME screen, just keep touching the Previous Menu button until you see the HOME button. Thus at that point, just press HOME to get back to the Home screen.
Setting Temperature Limits
To adjust temp limits for this t-stat, tap the MENU item as shown in the next picture.
Also, the temp limits screen allows you to set the lowest and highest temperatures that this thermostat will attempt to control in your home.
The max and min settings appear highlighted in the next pictures.
Furthermore on this t-stat, you can set the lowest possible temperature that it will try to cool the room down to. Once you set this, you will not be able to lower the t-stat temperature setting below this number.
Honeywell Thermostat Pictures Gallery: The Cool On Message
Now this t-stat shows this message when the HVAC AC is running. This happens when the room warms above the set temp, and then the t-stat calls for cooling.
Waiting for Equipment Message
This t-stat displays this message right after power up, should the set temperature and actual room temperature call for the HVAC system to run. You also get this if the HVAC system has just turned off, but you set the temperature so that the t-stat calls for more HVAC heating or cooling. The message clears after several minutes, allowing normal operation to resume.
Honeywell Thermostat Pictures Gallery: Waiting for Update Message
This t-stat displays this message right after power up, and before it receives the next outdoor temperature update from the internet.
Then, once it does get it, the t-stat shows the outdoor temperature and humidity it received. Note that these numbers do not come from any sensors attached to this t-stat. There are no such sensors.
