In a single duct system, the TV-UCXP683T-V controls airflow using the built-in flow sensor and external actuator.
In a dual duct system, the TV-UCXP683T-V controls airflow for one duct using the built-in flow sensor and external
actuator. For the other duct, the TV-UCXP683T-V uses the VAV Zone II Secondary Duct, which has its own flow
sensor and actuator. Connect both the TV-UCXP683T-V actuator and the VAV Zone II Secondary Duct to the TV-
UCXP683T-V
Act Net
port.
To connect duct tubes to the flow sensors
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
1
Turn off the TV-UCXP683T-V's power.
2
Connect the tube to the TV-UCXP683T-V's
High
connector and the
Low
connector. Then connect those tubes
to the duct's high and low pressure tubes. Avoid sharp bends in the tubing.
For a dual duct system
1
Follow the single duct procedure above to connect the TV-UCXP683T-V to the cold duct's tubes.
2
To connect the VAV Zone II Secondary Duct to the second duct's tubes, turn off the VAV Zone II Secondary
Duct's power.
3
Connect the secondary tubes to the duct's high and low pressure tubes. Avoid sharp bends in the tubing.
