Try These: To cancel the temporary setting at any time, press CANCEL. Press HOLD to permanently adjust the temperature. This will over- ride the temperature settings for all time periods. The "Hold" feature turns off the program schedule and allows you to adjust the thermostat manually, as needed.

How do I take my Honeywell thermostat off temporarily?
To cancel the temporary setting at any time, press CANCEL. Press HOLD to permanently adjust the temperature. This will over- ride the temperature settings for all time periods. The "Hold" feature turns off the program schedule and allows you to adjust the thermostat manually, as needed.
What is temporary hold on Honeywell thermostat?
The temporary hold setting is when you change the temperature setting to a different temperature and it stays at that setting until the next schedule change. The permanent hold setting holds the temperature setting you have chosen for an indefinite time. This overrides your scheduled settings. Thanks for your feedback!
How do I manually override my Honeywell thermostat?
Override a Home Honeywell Thermostat
Keep the display button depressed and let go of the off button. While still holding the display button, quickly press the up arrow button. Release all depressed buttons at the same time. This should put the thermostat in a manual mode.
