General
The RDV/RDVQ is supplied with the duct, damper, and airflow
sensor. The RDV/RDVQ assembly is designed to accept Direct
Digital Controls (DDC) for VAV pressure independent operation.
The terminal unit controls are supplied by the controls
contractor and either factory or field mounted and wired. For
information concerning controls, components, sequence of
operation, etc., please refer to the documentation provided by
the controls contractor.
Receiving Inspection
After unpacking the assembly, check it for shipping damage.
If any shipping damage is found, report it immediately to the
delivering carrier. During unpacking and installation do not
handle by the inlet velocity sensor, damper shaft, or tubing.
Damage may result.
Wiring
If controls have been factory mounted, a wiring diagram
will be included with the unit indicating the factory mounted
components. For field wiring of room sensors and other
accessories, refer to the controls contractor's documentation.
If the controls have been field mounted, refer to the controls
contractor's documentation for all wiring information.
Damper rotation is always clockwise to the open position.
An identification mark on the end of the shaft indicates the
damper position.
The factory supplied sensing lines are color coded. Red
indicates the total pressure or ”HI“ line which should be
located on the upstream side. Green indicates the static
pressure or ”LO“ line which should be located on the
downstream side.
An optional protective enclosure may be provided to house
the terminal unit control components. The enclosure cover is
removable with two sheet metal screws.
