Building Pressure Control Output
The Building Pressure Control Output is a 0-10 VDC or 2-10 VDC signal
sent from the VCM-X Expansion Module. When using the output for
Direct Building Pressure Control (output signal rises on a rise in build-
ing pressure), the output signal can be connected to either a Variable
Frequency Drive controlling an exhaust fan or to a damper actuator
controlling an exhaust damper. When used in this manner, the output
signal must be confi gured for Direct Acting operation.
When using this output for Reverse Building Pressure Control (output
signal rises on a fall in building pressure), a damper actuator controlling
an OA Damper would be used. When using the OA damper for Reverse
Building Pressure Control, the output signal must be confi gured for
Reverse Acting operation. A Building Pressure Sensor connected to
AI4 on the VCM-X Expansion Module is used to sense and control the
signal to the Building Pressure Output. The OE258-01 Building Pressure
Sensor must be connected in order for the Building Pressure Output to
operate correctly.
See Figure 27 below for detailed wiring of the Building Pressure Control
Output Signal.
Caution:
Variable Frequency Drive units can cause large transient
noise spikes that can cause interference to be propagated on other
electronic equipment. Use shielded wire wherever possible and route
all sensor and controller wiring away from the Variable Frequency
Drive and the HVAC unit electrical wiring.

WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-to-24VAC.
Failure to observe polarity will result in damage to one or more of the boards. Expansion
Modules must be wired in such a way that the expansion modules and the controller are
always powered together. Loss of power to the expansion module will cause the controller
to become inoperative until power is restored to the expansion module.
