NOTE(S):

BP 1 Actuator Max Pos. (BP.1M)
For BP.CF = 2, this configuration is the maximum actuator no. 1
position during building pressure control.
BP 2 Actuator Max Pos. (BP.2M)
For BP.CF = 2, this configuration is the maximum actuator no. 2
position during building pressure control.
BP Hi Cap VFD Clamp Val. (BP.CL)
For BP.CF = 4, this configuration is a limit that creates a deadband
which controls the action of the second power exhaust relay.
Fan Track Learn Enable (FT.CF)
WARNING
Fan tracking learning is a system dependent operation and
should not be used with default values.
Do not use the fan track learning disable setting unless a system
air balance has been done to determine the correct FT.MX and
FT.MN values. Allowing these values to run without proper
clamps can cause system damage inside the building.

For BP.CF = 5, this return/exhaust control configuration selects
whether the fan tracking algorithm will make corrections over
time and add a learned offset to FT.ST. If this configuration is set
to No, the unit will try to control the delta cfm value between the
supply and return VFDs only based on FT.ST.
Fan Track Initial DCFM (FT.ST)
For BP.CF = 5, this return/exhaust control configuration is the
start point upon which corrections (offset) are made over time
when FT.CF = Yes. It is the constant control point for delta cfm
control when FT.CF = No.
Fan Track Minimum Clamp (FT.MN)
For BP.CF = 5, this return/exhaust control configuration is the
minimum positive delta cfm control value allowed unless outdoor
air cfm control is available and then the delta cfm control value
would be clamped to the outdoor air cfm value directly (see the
Economizer section on page 75 for a description of outdoor air
cfm configuration).
Fan Track Max Clamp (FT.MX)
For BP.CF = 5, this return/exhaust control configuration is the
maximum positive delta cfm control value allowed unless outdoor
