* Early Start is used in Automatic mode only. When Early Start is enabled (On), the thermostat determines
when to start heating so the desired temperature be reached at the beginning of periods 1 and 3. When
Early Start is disabled (Off), heating does not start in advance, and therefore the desired temperature will
not yet be reached at the beginning of these periods.
** When Automatic Daylight Saving Time is enabled (On), the thermostat automatically switches to
daylight saving time on the second Sunday of March and to normal time on the first Sunday of November.
