Air Flow Pick-up

Connect the air flow pick-up to the two connectors on the 
CPO-VAV2A. See Figure 11. Connect the high pressure or 
upstream tube to the air flow pick-up connector labeled (H) 
and the low-pressure or downstream tube to the connector 
labeled (L).

Best practice for zero calibration of air flow 
sensor

The controller must be powered up for a minimum of 1 hour 
before performing the zero calibration for the air flow sensor.

Serial Number Label

There is a separate label with product serial number in the unit 
pack. The user can choose to paste this label on the front of 
housing to easily check the product serial number.
