Duct Static Pressure Sensor Testing
The table below is used to troubleshoot the Duct Static Pressure
Sensors.
Duct Static Pressure Sensor Testing
Instructions
Use the voltage column to check the Duct Static Pressure Sensor
while connected to powered controllers. Read voltage with meter
set on DC volts. Place the “-” (minus) lead on the GND terminal
and the “+” (plus) lead on the right side of the resistor labeled
R85. Be sure to replace the jumper after checking.

Building Pressure Sensor Testing
The table below is used to troubleshoot the Building Pressure
Sensors.
Building Pressure Sensor Testing Instructions
Use the voltage column to check the Building Static Pressure
Sensor while connected to a powered expansion module. Read
voltage with meter set on DC volts. Place the “-” (minus) lead
on terminal labeled GND and the “+” lead on terminal AI5 on
the VCCX2 Controller.
