How do I set the time and day on the thermostat?

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