How do I set the time and date on my Honeywell thermostat?

To set the time, press Menu, navigate to TIME using arrow buttons, press Select, choose between 12 or 24-hour format, then adjust hours and minutes with arrow buttons, pressing Select to confirm. To set the date, press Menu (or continue from time setup), navigate to DATE, then use arrow buttons to adjust year, month, and day in sequence, pressing Select after each adjustment. Press Select again to save and exit the date menu.
