Description
The OE521-XX-T Round Pressure
Independent Zone Damper Assembly with
terminal connectors consists of a round
air damper with air flow pickup cross and
a Zone Controller Actuator Package
(including air flow sensor) with terminal
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 Independent Zone Dampers are
used in air conditioning systems require
pressure independent airflow control. If
your system requires pressure dependent
control of the airflow, see the “OE520-XX-T Round Pressure Dependent 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.
