NOTE: These configurations are used only if Fan Track Learning
is enabled. When Fan Track Learning is enabled, the control will
add an offset to the Fan Track Initial DCFM (Configuration
BP
FAN.T
FT.ST) if the building pressure deviates from the
Building Pressure Set Point (BP.SP). Periodically, at the rate set
by the Fan Track Learn Rate (FT.TM), the delta cfm is adjusted
upward or downward with a maximum adjustment at a given in-
stance to be no greater than Fan Track Max correction (FT.AD).
The delta cfm cannot ever be adjusted to be greater than or less
than the Fan Track Max Clamp (FT.MX) or less than the Fan
Track Minimum Clamp (FT.MN). Fan track learning will not
work properly unless the air balancer has determined the FN.MX
and FN.MN for the building. A single delta as determined via a
system air balance should be adequate; otherwise, select one of
the direct BP controls.

Programming Operating Schedules
The ComfortLink controls will accommodate up to eight different
schedules (Periods 1 through 8), and each schedule is assigned to
the desired days of the week. Each schedule includes an occupied
on and off time. For example, to set an occupied schedule for
8 AM to 5 PM for Monday through Friday, set days Monday
through Friday to ON for Period 1. Then configure the Period 1
Occupied From point to 08:00 and the Period 1 Occupied To point
to 17:00. To create a different weekend schedule, use Period 2 and
set days Saturday and Sunday to ON with the desired Occupied
On and Off times.
