1. Early Start is used in Automatic mode only. When Early Start is enabled (on), the thermostat
determines when to start heating so the Comfort temperature is attained at the beginning of
periods 1 and 3. When Early Start is disabled (off), heating starts only at the beginning of periods
1 and 3; thus there is a delay before the Comfort temperature is reached.
