How do I set the time and day on the TH6110D thermostat?

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, then press DONE to save and exit. Note that if the display flashes 'Set Clock,' the thermostat will follow your weekday 'Wake' settings until the time and day are properly set. (Page 6)
