Description
The OE520-XX-T Round Pressure Dependent
Zone Damper Assembly with terminal
connectors consists of a round air damper
and Zone Controller Actuator Package with
terminal wiring connectors. An optional Zone
Controller Expansion Module (OE325-01) is
available for control of reheat, heat and/or
control of series or parallel flow fan terminal
units.
The Zone Controller board is microprocessor
based and communicates with the HVAC unit
controller on the Orion network
communications loop. The Zone Controller
monitors the space temperature and allocates
the proper airflow into its assigned space to
achieve the desired comfort and ventilation
levels.
Pressure Dependent Zone Dampers are used
in air conditioning systems that do not require
pressure independent airflow control. If your
system requires pressure independent control
of the airflow, see the “OE521-XX-T Round
Pressure Independent Zone Damper”
submittal sheet for the correct specifications. All dampers are tested for performance in accordance with AMCA
500D standards.
Mounting
The Zone Damper Assembly should be mounted according to standard duct installation practices with airflow
direction as shown in the illustration above. After installation of the Zone Damper in the ductwork, insulation
should be applied around any remaining un-insulated surface on the damper inlet and outlet. The Zone Damper
should be mounted so the control enclosure is positioned to the left or right side of the ductwork with the control
enclosure in a vertical plane. Do not mount the Zone Damper Assembly with the control enclosure on the top or
bottom of the ductwork. Adequate clearance should be maintained between the control panel and any
obstruction to allow for removal of the control panel cover and access to the controls.
