Description The OE282-01 Zone Damper Actuator is a shaft mounted, floating point control actuator with an included phone jack cable. Actuators are 24VAC/24VDC with a 10K ohm feedback signal for position monitoring. Wiring connection to the actuator is by means of a modular phone cable connector located on the actuator cover. The actuator is rated for 45 in-lb of torque. All actuators are electronically protected against overload. The angle of rotation is mechanically limited to 95. When the end position of the actuator or damper is reached, the actuator automatically stops. For adjustment purposes, the gears can be manually disengaged by pushing the manual override button on the actuator cover. Applications The OE282-01 Zone Damper Actuator is used to provide control of air volume dampers in a VAV or Zoning system. The actuator is included in the OE742-01P-VAVZ or OE742-03P-VAVZ. P.D. VAV/Zone Controller Packages or the OE744-01P-VAVZ and OE744-03P-VAVZ. P.I. VAV/Zone Controller Packages.

Description The OE325-03 VAV/Zone Controller Expansion Module is used in conjunction with the OE326-23I-OR & OE326-23D-OR VAV/Zone Controller to allow for control of fans included in series and parallel flow fan terminal units and/or additional staged or modulating heat. It can also control up to 3 stages of electric heat, SCR electric heat, on/off HW heat, or modulating hot water heat. The OE325-03 VAV/Zone Controller Expansion Module provides 4 relay outputs for pilot duty switching control, (1 fan and 3 heat) relay outputs and 1 analog output for control of a 0-10V modulating hot water valve or SCR controlled electric heating coil. The OE325-03 VAV/Zone Controller Expansion Module connects to the controllers mentioned previously by means of an E-BUS cable that is provided with the Expansion Module. Power to this board is also supplied to the board by means of this E-BUS cable for the VAV/Zone Controller. De-pluggable screw terminals are provided for connection of field wiring to the relays outputs, the analog outputs, and the binary input (not used in this application). The relay outputs are N.O. contacts with one common terminal. All outputs and the relay common are electrically isolated from all other circuitry on the board. All relay outputs are supplied with transient suppression devices across each set of contacts to reduce EMI and contact arcing. The relay output circuits are rated for pilot duty control of a maximum of 1 Amp @ 24 VAC or 24 VDC each. These outputs require a separate 24 VAC transformer provided by others. The analog output provides a 0-10 VDC modulating signal output into a 1K Ohm minimum load. If a Modulating Hot Water Valve is being used, it will also need a 24 VAC transformer by others for its power source. Mounting The OE325-03 VAV/Zone Controller Expansion Module is supplied mounted on a plastic snap track channel. The snap track channel has a single mounting hole which is used to field mount the board with the provided screw. The module should be mounted in close proximity to the VAV/Zone Controller to allow for connection with the supplied E-BUS cable.

Description The OE520-XX-PT Round Pressure Dependent Zone Damper Assembly with terminal block connectors consists of a round air damper and the OE742-01P-VAVZ VAV/Zone Controller Package with terminal block wiring connectors. An optional VAV/Zone Controller Expansion Module (OE325-03) is available for control of reheat, auxiliary heat and/or control of series or parallel flow fan terminal units.
The VAV/Zone Controller board is microprocessor based and communicates with the HVAC unit controller on the Orion local communications loop. The VAV/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-PT 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 that 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.

Using the maximum acceptable velocity for a branch duct (typically 1000-1500 FPM for minimal noise), find the smallest Zone Damper that will deliver the required CFM as determined by the load program. Locate the branch velocity used in the duct design program in the left hand column of the Zone Damper Selection Data table. Move across the table and find the Zone Damper, which will provide the acceptable CFM to meet the zone airflow requirements.
Note: Compare the Zone Damper size selected against the duct size to determine if the next size up or down will provide acceptable performance without requiring a transition fitting.
Up to a maximum of two Slaved Zone Dampers may be slaved together with the main Zone Damper for large zones. This design should be reserved only for situations when it is not practical to use a single Zone Damper. See the Pressure Independent Zone Damper submittal sheet submittal sheet for information regarding application and selection of Round Slaved Zone Dampers.

Description The OE736-03-PT P.D. Rectangular Damper Kit with Terminal Blocks provides the latest solution for rectangular zone damper applications. The Rectangular Damper Kit is used in conjunction with rectangular dampers for applications where rectangular dampers are specified or required because of space limitations or job requirements. The Rectangular Damper Kit includes the OE742-01P-VAVZ VAV/Zone Controller Package mounted in a metal enclosure. The rectangular dampers may be purchased from WattMaster or you may get them from the supplier of your choice. For proper control, WattMaster recommends the use of low leakage opposed blade dampers. The maximum allowable damper face area for the Rectangular Damper Kit is 6 sq. ft.
Mounting Before mounting the Rectangular Damper Kit, the rectangular damper should be mounted in the ductwork according to standard duct installation practices. The damper should be mounted so the damper shaft turns in a clockwise direction to open the damper. The Rectangular Damper Kit is simply slid over the damper shaft, the actuator shaft collar setscrews tightened and the supplied self-tapping screws are used to mount the enclosure to the ductwork. Detailed mounting and installation instructions are provided with each kit. A knockout is provided in the front access cover, which can be punched out to allow for damper shaft lengths, which extend past the enclosure depth. When mounting the Rectangular Damper Kit, be sure to allow clearance for removal of the access cover. Conduit knockouts are provided in the top and bottom of the enclosure for simplified wiring installation.

DescriptionThe OE519 Rectangular Damper is usedin applications where rectangular duct isspecified or required because of spacelimitations or job requirements. The Rec-tangular Damper utilizes opposed bladesof airfoil design for improved air flow con-trol. The Rectangular Damper frame ismade of .080 thick extruded aluminum.The blades are also made of extrudedaluminum. Blade pins are 7/16” hexagonshaped aluminum fixed to a Celcon innerbearing rotating within a polycarbonateouter bearing inserted in the damperframe. The Damper linkage is mechani-cally assembled and located in thedamper frame. The linkage componentsare constructed of aluminum, zinc andnickel plated steel. Blade gaskets aremade of extruded EPDM material and aresecured within an integral slot on theblade. Jamb seals are of extruded TPEmaterial for low leakage through thedamper when closed. The control shaft is1/2” diameter hexagon shaped rod andcan be extended 9” past the damperframe for connection to the damper ac-tuator. The damper shaft is shipped re-tracted into the frame area and must beadjusted to the required length in the field.
MountingThe Rectangular Damper should bemounted in the ductwork according to standard duct installation practices. The rectangular damper should be se-lected for the nominal inside duct size. All Rectangular Dampers are supplied with 1” flanges all around damperframe, making the overall damper width and height 2” larger than the nominal inside duct size thus providing forexternal flange mounting to ductwork. The damper shaft is shipped retracted into the damper frame. Loosen thetwo nuts on the U-bolt that secures the damper shaft to the damper blade and adjust to length. It is recommendedthat the shaft length be adjusted so approximately 4” of shaft extends beyond the inside of the damper frame.Retighten the two nuts on the U-bolt that secures the damper shaft to the blade. After installation of the Rectan-gular Damper to the ductwork, it is recommended that insulation be applied around any non-insulated surface onthe ductwork where the Rectangular Damper was installed.
Damper SizingUse a load program to determine the peak load for each zone. These calculations will be used in selecting theappropriate Rectangular Damper sizes. The Orion Systems utilize a typical low pressure duct design. To reducenoise problems, duct pressures should not exceed 1” W.C.
Primary trunk ducts used with Orion systems should not be “undersized”. This is especially true of “pressure de-pendent” systems. With pressure independent systems this is not as critical. With larger trunk ducts, it is easier toassure relatively constant pressure to each Rectangular Damper. Runs should be as short as possible, and thetrunk duct system kept as symmetrical as possible to facilitate system balancing. Wherever possible, run the trunkducts above corridors and locate the Rectangular Dampers above corridors to reduce the noise in the space andfacilitate service of the valves. Trunk ducts should be sized for no more than 0.1” W.C. drop per 100 ft. of duct,and a maximum duct velocity of 2000 FPM.

Notes:1. The table above is calculated based on 1000 FPM velocity across the full open damper. For other velocities use the
following multipliers to obtain the correct CFM: 500 FPM = 0.5, 1500 FPM = 1.5, 2000 FPM = 2.0. It is recommendedthe damper velocity does not exceed 1500 FPM for quiet operation.
2. Pressure drop (∆PS) is based on 1000 FPM Velocity. Any pressure drop less than 0.01” W.C. is shown as (-).
This is the recommended velocity for quiet operation and nor-mal pressure drop through the damper. When space consid-erations or design criteria dictate, dampers may be selected forother face velocities by using the multipliers listed in the notesassociated with the table. Move across the table and find thedamper selection, which will provide the required CFM and fitwithin the ceiling area where the damper will be located. Manysize selections are possible for a given CFM. Pressure dropacross the damper is shown in parenthesis below the CFM.

Form: Orion-OE737-RectBypKit-Sub-01B Page 1 of 1
DescriptionThe OE737 Rectangular Bypass Damper Kitmounts to an OE519 Rectangular Damperand controls duct static pressure to insureproper system airflow. The Rectangular By-pass Damper is controlled by the OrionHVAC Unit Controller. The Unit Controllermodulates the Rectangular Bypass Damperin response to the duct static pressure basedon a signal received from a static pressuresensor located in the main system ductwork.
The Rectangular Bypass Damper Kit is usedin conjunction with rectangular dampers forapplications where rectangular dampers arespecified or required because of space limi-tations or job requirements. The rectangulardampers may be purchased from WattMas-ter or you may get them from the supplier ofyour choice. For proper control, WattMasterrecommends the use of low leakage op-posed blade dampers. The maximum allow-able damper face area for the RectangularBypass Damper Kit is 6 sq. ft. The Rectan-gular Bypass Damper Kit comes packagedwith the Damper Actuator and Wiring Interface pre-mounted in a galvanized steel enclosure. Each kit is suppliedwith mounting hardware and installation instructions. For applications where CFM or space requirements dictatethe use of more than a single bypass damper, up to 2 additional bypass dampers can be slaved together. Noother components are required. Each bypass is wired to the other bypass damper(s) by means of the Wiring In-terface.
MountingBefore mounting the Rectangular Damper Kit, the rectangular damper should be mounted in the ductwork ac-cording to standard duct installation practices. The damper should be mounted so the damper shaft turns in aclockwise direction to open the damper. The Rectangular Damper Kit is simply slid over the damper shaft, theactuator shaft collar setscrews tightened and the supplied self tapping screws are used to mount the enclosure tothe ductwork. Detailed mounting and installation instructions are provided with each kit. A knockout is provided inthe front access cover, which can be punched out to allow for damper shaft lengths, which extend past the enclo-sure depth. When mounting the Rectangular Damper Kit, be sure to allow clearance for removal of the accesscover. Conduit knockouts are provided in the top and bottom of the enclosure for simplified wiring.

DescriptionThe OE738 Rectangular Slaved-VAV/ZoneDamper Kit provides a new solution for rectan-gular damper applications. The OE738 Rectan-gular Slaved-VAV/Zone Damper Kit is used inconjunction with rectangular dampers for appli-cations in systems when it is not possible orpractical to use a single large RectangularVAV/Zone Air Damper to satisfy the zones CFMrequirements.
The rectangular dampers may be purchasedfrom WattMaster or you may get them from thesupplier of your choice. For proper airflow con-trol, WattMaster recommends the use of lowleakage opposed blade dampers. The Rectan-gular Slaved-VAV/Zone Damper Kit is suppliedwith the slave wiring interface card and actuatorfactory mounted in a sheet metal enclosure. Atotal of two Slaved-VAV/Zone Air Dampers maybe used in conjunction with a master Rectan-gular VAV/Zone Damper Kit. The RectangularSlaved-VAV/Zone Air Damper(s) are wired inparallel with the master Rectangular VAV/ZoneDamper Kit and track the movement of themaster Rectangular VAV/Zone Damper. Connection to the master Rectangular VAV/Zone Damper Kit requires aSlave Wiring Adapter Kit, part # OE267 which is supplied with each Rectangular Slaved-VAV/Zone Damper Kit.The kit connects the zone controller on the master to the master actuator and provides wiring terminals for wiringto the Rectangular Slaved-VAV/Zone Damper Kit(s). Only one Slaved Wiring Kit is required for each Slaved-VAV/Zone system. Each kit is supplied with mounting hardware and installation instructions.
MountingThe rectangular damper should be mounted in the ductwork according to standard duct installation practices be-fore installing the Rectangular Slaved-VAV/Zone Damper Kit. The Rectangular Slaved-VAV/Zone Damper Kit issimply slid over the damper shaft, the actuator shaft collar setscrews tightened and the supplied self tappingscrews are used to mount the enclosure to the ductwork. Detailed mounting and installation instructions are pro-vided with each kit. A knockout is provided in the front access cover, which can be punched out for damper shaftlengths which extend past the enclosure depth. When mounting the Rectangular Slaved-VAV/Zone Damper Kit,be sure to allow clearance for removal of the access cover.

Description The OE282-03 Slaved VAV/Zone Damper Kit consists of an OE282 Damper Actuator, (2) PL101824 Slave Wiring Interface Boards and (2) 18” Long Modular Cables. The OE282 Actuator is a shaft mounted, floating point control actuator. The actuator is a 24VAC/24VDC model with a 10K ohm feedback signal for position monitoring. Wiring connection to the actuator is by means of a modular phone cable connector located on the actuator cover. The actuator is rated for 45 in-lb. of torque. All actuators are electronically protected against overload. The angle of rotation is mechanically limited to 95. When the end position of the actuator or damper is reached, the actuator automatically stops. For adjustment purposes, the gears can be manually disengaged by pushing the manual override button on the actuator cover. Applications The OE282-03 Slaved VAV/Zone Damper Kit allows multiple dampers (up to 2 total besides the master) to be connected to a master OE742-31-VAVZ or OE742-32-VAVZ P.D. VAV/Zone Controller Actuator Package. The OE282-03 Kit is typically used when larger CFM requirements dictate multiple dampers are used. One of the Interface Boards connects to the master VAV/Zone Controller via a modular cable. The other Interface Board connects to the Slave Damper Actuator. Three conductor wiring is then routed and connected between the two Interface Boards. For zones requiring more than one Slave Damper Kit a second one can be purchased and installed in the same manner.
