If you are using the internal time clock of the Zone Manager and
you have entered a “0” on the Schedule Configuration screen,
you can enable this internal schedule to perform an optimal
start. The Target Zone is the zone that you choose, to be the
control point. In other words the zone that you choose will be
the one that is used to determine how early the unit should start
in order to bring that zone under control by the time the space is
occupied. If you input a –1 for the Target Zone, it averages all
of the zones instead of controlling just one. The Soak Multiplier
is used to increase the normal optimal start calculation
whenever the building has been unoccupied for 24 consecutive
hours or more. If you enter a “0” for the Soak Multiplier
optimal start will be disabled. If you use a 1.5 multiplier and the
optimal start had calculated a 30 minute pre-start, the soak
multiplier would add an additional 15 minutes to the pre-start
for a total of 45 minutes (1.5 x 30). The system would then start
45 minutes earlier than normal scheduled time.
