Table 66 — Building Pressure Configuration
*Some configurations are model number dependent.
Building Pressure SETP (BP.SP)
This set point is the building pressure control set point. If the
unit is configured for a type of modulating building pressure
control, then this is the set point that the control will control to.
BP Setpoint Offset (BP.SO)
For building pressure configurations BP.CF=2, 3, and 4, this is
the offset below the building pressure set point that the build-
ing pressure must fall below to turn off power exhaust control.
Power Exhaust on Setp.1 (BP.P1)
When configured for building pressure control type BP.CF = 1
(constant volume two-stage control), the control will turn on
the first power exhaust fan when the economizer’s position ex-
ceeds this set point.
Power Exhaust on Setp.2 (BP.P2)
When configured for building pressure control type BP.CF = 1
(constant volume two-stage control), the control will turn on
the second power exhaust fan when the economizer’s position
exceeds this set point.
VFD/Act. Fire Speed/Pos (BP.FS)
For BP.CF = 2, 3, 4, and 5, this configuration is the VFD
speed/actuator position override when the control is in the
purge and evacuation smoke control modes.
VFD/Act. Min Speed/Pos (BP.MN)
For BP.CF = 2, 3, 4, and 5, this configuration is the minimum
VFD speed/actuator position during building pressure control.
VFD Maximum Speed/Pos (BP.MX)
For BP.CF = 3 and 5, this configuration is the maximum VFD
speed during building pressure control.
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.
