Using The Static Pressure Sensor; To Connect The Duct Tube(S) To The Static Pressure Sensor - Carrier TruVu VVTBP-E2 Installation And Startup Manual

Using the static pressure sensor

In a single duct system, the TV-VVTBP-E2 maintains supply duct static pressure by regulating airflow using the
built-in static pressure sensor and internal actuator.

To connect the duct tube(s) to the static pressure sensor

NOTE Tubing should be at least 2 ft. (.61 meters) long for stable airflow measurement. The combined high and
low tubing length should not exceed 16.4 ft. (5 meters) in order to ensure accurate measurements.
For a single duct system
Turn off the TV-VVTBP-E2's power.
1
Connect the tubes to the TV-VVTBP-E2's airflow (pressure) sensor port. Then connect those tubes to the
2
duct's high and low pressure tubes. Avoid sharp bends in the tubing.
NOTE You can connect the duct's high and low pressure tubes to either port. The TV-VVTBP-E2 automatically
determines the polarity and calculates for positive flow. The Driver Properties > Flow Calibration Archive
page displays the tubes' polarity.
