Notes for terminal units for duct pressure control
The accessibility of the connections for the differential pressure sensors varies depending on the version of
the VAV terminal unit, and the control components installed.
VAV terminal units intended for duct pressure control require a suitable pressure tapping point in the duct
system to be controlled. In VAV terminal units with control components for duct pressure control, the differen-
tial pressure sensor installed in the VAV terminal unit has no function and is therefore either not accessible or
designed without tubing to the control component.
