How do I set the time and day on my Honeywell FocusPro TH6220D?

Press the SET CLOCK/DAY/SCHEDULE button, then press the up or down arrow to set the clock time. Next, press the SET DAY button and use the arrows to select the current day of the week. Press DONE to save and exit. If the display flashes 'Set Clock,' the thermostat will follow your weekday Wake period settings until the time and day are properly set. (Page 6)
