VCCX2 Controller Technical Guide
Duct Static Pressure Transducer
The ASM01640 Duct Static Pressure Transducer plugs directly
into the VCCX2 Controller’s static pressure port. The Duct Static
Pressure Sensor reading is used to determine current duct static
pressure. This static pressure reading is used to control the output
signal supplied to the Supply Fan VFD or Zoning Bypass Damper
Actuator. If you have congured the HVAC unit for constant
volume operation, this sensor is optional. If it is installed on a
constant volume unit, it will not aect operation, but rather will
be used as a status-only reading. See Figure 19, this page for
detailed wiring.
CAUTION: It is strongly recommended that you use
pneumatic tubing instead of relocating the
sensor. Extending the wires could cause
voltage drop problems.
