How do I set up a vacation hold on the thermostat?

Press the up or down arrow to set the desired temperature, then press HOLD twice so that 'Hold Until' appears, and press the arrows to select the number of days. The selected temperature will be maintained 24 hours a day for the number of days chosen, after which the previously programmed schedule will resume at the time you set. You can press CANCEL or SCHED at any time to resume the normal schedule. (Page 42)
