Your Honeywell thermostat has a holiday settings option that most users use when they are going away from their homes for an extended period.

7. Replace the Thermostat Batteries
If your thermostat uses a battery then there is a possibility of a low charge or other defect, which is preventing the schedules from executing.
Sometimes even if your Honeywell thermostat is working, the charge from the batteries could be weak or fluctuating.
The Honeywell Thermostat uses two AAA batteries!
So, it’s very important to check whether the batteries are dead by installing a fresh pair, that you can purchase online or at any convenient store.
We strongly recommend not skipping this step!
Note: It’s good to install a fresh set of batteries in your Honeywell thermostat once every year.
8. Factory Reset the Thermostat
If you have tried all steps but nothing works then perform a factory reset on your Honeywell thermostat only as a last resort.
This method will clear all settings and configurations and will initialize your thermostat, where the data loss is irreversible.
Here’s how to factory reset the Honeywell thermostat in easy steps:
- Press the Menu icon on your Honeywell thermostat.
- Scroll down and tap on the “Advanced Setup” tab.
- Tap on “Reset” and then choose “Factory Reset”.
- Alternatively, install the thermostat batteries incorrectly.
- Info: The batteries must be facing the incorrect poles.
- After a few seconds, reinstall the batteries correctly.
- This will reset the Honeywell thermostat to default.
Once your thermostat factory resets completely, then set it up again to get full control of your home.
If you need further help or the scheduling problem persists, contact Honeywell Support.
