The Auto-Zone Basic control system converts a sin-gle zone HVAC unit into a variable air vol-ume/variable air temperature multiple zone system.The microprocessor based Zone Manager calculatesthe heating and cooling requirements for each zonebased on real time information received from eachZone Controller. The Zone Manager then directs theHVAC unit to provide the appropriate amount of

heating, cooling, and ventilation to satisfy eachzone's requirements. A static pressure sensor, whichmodulates a bypass damper, maintains a constantsystem duct pressure.

Substantial savings can be realized using the Auto-Zone Basic system instead of installing multipleHVAC units to accommodate multiple zones. TheAuto-Zone Basic system is versatile and can beused with any 3-40 ton HVAC unit. It controls a vari-ety of terminal units including single duct pressuredependent or pressure independent zone damper.

User friendly, menu driven, fill in the blank pro-gramming, makes the Auto-Zone Basic easy to setup and operate without the need for specializedtraining.

DescriptionThe OE510 Pressure Dependent ZoneDamper consists of a round air damper,zone controller, and actuator. An optionalauxiliary relay board (OE321) is availablefor control of auxiliary heat and/or controlof series or parallel flow fan terminal units.

The Zone Controller (OE320) is micro-processor based and communicates withthe Zone Manager on the Auto-Zone net-work communications loop. The ZoneController monitors the space temperatureand allocates the proper airflow into itsassigned space to achieve the desiredcomfort and ventilation levels.

Pressure Dependent Zone Dampers areused in air conditioning systems that donot require pressure independent airflowcontrol. If your system requires pressureindependent control of the airflow, see theOE511 - Pressure Independent ZoneDamper data sheet for the correct specifi-cations.

All Zone Dampers are tested and certifiedin accordance with ARI standard 880. AnARI label is affixed to all units.

MountingThe Zone Damper assembly should be mounted according to standard duct installation practices with airflow di-rection as shown in the illustration above. After installation of the Zone Damper in the ductwork, insulation shouldbe applied around any remaining uninsulated surface on the air valve inlet and outlet. The Zone Damper shouldbe mounted so the control enclosure is positioned to the left or right side of the ductwork with the control enclo-sure in a vertical plane. Do not mount the Zone Damper Assembly with the control enclosure on the top or bottomof the ductwork. Adequate clearance should be maintained between the control panel and any obstruction to allowfor removal of the control panel cover and access to the controls.

Zone Damper SizingUse a load program to determine the peakload for each zone. These calculations will beused to select Zone Damper sizes.

The Auto-Zone Systems utilize a typical lowpressure duct design. To reduce noise prob-lems, duct pressures should not exceed 1W.C.

Primary trunk ducts used with Auto-Zonesystems should not be undersized. This isespecially true of pressure dependent sys-tems. With larger trunk ducts, it is easier toassure relatively constant pressure to eachZone Damper. Runs should be as short aspossible, and the trunk duct system kept assymmetrical as possible to facilitate systembalancing. Wherever possible, run the trunkducts above corridors and locate the ZoneDampers above corridors to reduce the noise

in the space and facilitate service of thevalves. Trunk ducts should be sized for nomore than 0.1 W.C. drop per 100 ft. of duct,and a maximum duct velocity of 2000 FPM.

Using the maximum acceptable velocity for abranch duct (typically 1000-1500 FPM forminimal noise), find the smallest ZoneDamper that will deliver the required CFM asdetermined by the load program.

Bypass Damper SizingBecause the zones in an Auto-Zone Systemare controlled using variable air volume, it isunlikely that all zones will be at design loadat the same time. This zoning allows forload diversity to be taken into account when

sizing the central HVAC unit. This typicallywill provide better comfort with a smallerHVAC unit than with the use of a constantvolume system. Use a load program to de-termine the individual zone loads. Becauseof zone diversity the HVAC unit should besized for the correct instantaneous peakload, not the sum of the peak loads aswould be the case when sizing a normalconstant volume unit system. The BypassDamper should be sized to provide for themaximum amount of air to be bypassed inthe system. This is typically 60 to 70% ofthe HVAC units rated capacity. These cal-

culations will be used in selecting the ap-propriate Bypass Damper Size(s).

The Auto-Zone Systems utilize a typical lowpressure duct design. To reduce noiseproblems, duct pressures should not ex-ceed 1 W.C..

Using the maximum acceptable velocity fora bypass duct (typically 1750-2250 FPM forminimal noise), find the smallest damperthat will deliver the required CFM as deter-mined by the load program.

OE512-Bypass Damper

When determining the bypass duct size, be sure to take into ac-count any transition fittings and their associated pressure drops.Locate the bypass duct velocity used in the duct design program inthe left hand column of the Bypass Damper Selection Data table.Move across the table and find the Bypass Damper size which will

provide the acceptable CFM to meet the bypass airflow require-ments.

Note: Compare the Bypass Air Damper size selected

against the bypass 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 additional Bypass Dampers may beslaved together with the main Bypass Damper for large bypassairflow requirements. This design should be reserved only forsituations when it is not practical to use a single large Bypass

Damper. The slaved valves should all be of the same size forproper control. Divide the total CFM by two or three depending onhow many bypass and slave dampers you will be using and sizeaccordingly.

DescriptionThe OE513 Slaved-Zone Damper Assembly,consists of a round air valve, actuator, (1)slave wiring interface card mounted in theenclosure. It also includes (1) slave wiringinterface card kit shipped loose for fieldmounting to the master zone damper as-sembly. This kit contains a slave wiring in-

terface card and a cable.The Slaved-Zone Damper, is used in sys-tems when it is not possible or practical touse a single large Zone Damper to satisfythe zones CFM requirements.

A total of two Slaved-Zone Dampers may beused in conjunction with a master ZoneDamper. The Slave Damper(s) are wired inparallel with the master Zone Damper andtrack the movement of the master ZoneDamper. Connection of the master ZoneDamper requires a slave wiring interface kitwhich is shipped loose for field mounting tothe master Zone Damper and is suppliedwith each Slaved-Zone Damper. The kit con-nects the Zone controller on the master tothe master actuator and provides wiring ter-minals for wiring to the Slaved-Zone Damp-ers. Only (1) of these kits is required for eachmaster/slave installation.

All Slaved-Zone Dampers are tested andcertified in accordance with ARI standard880. An ARI label is affixed to all units.

Mounting

The Slaved-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 Air Damper in the ductwork, insulationshould be applied around any remaining uninsulated surface on the air valve inlet and outlet. The Air Dampershould be mounted so the control enclosure is positioned to the left or right side of the ductwork with the controlenclosure in a vertical plane. Do not mount the Air Damper Assembly with the control enclosure on the top orbottom of the ductwork. Adequate clearance should be maintained between the control panel and any obstructionto allow for removal of the control panel cover and access to the controls.

Slaved-Zone Damper SizingUse a load program to determine the peak load foreach zone. These calculations will be used in se-lecting the appropriate Zone and Slaved-ZoneDamper sizes. Only pressure dependent ZoneDampers may be slaved.

The Auto-Zone Systems utilize a typical low pres-sure duct design. To reduce noise problems, ductpressures should not exceed 1 W.C.

Primary trunk ducts used with Auto-Zone systemsshould not be undersized. With larger trunkducts, it is easier to assure relatively constantpressure to each Zone Damper. Runs should beas short as possible, and the trunk duct systemkept as symmetrical as possible to facilitate sys-tem balancing. Wherever possible, run the trunkducts above corridors and locate the master Zoneand Slaved-Zone Dampers above corridors to re-

duce the noise in the space and facilitate serviceof the valves. Trunk ducts should be sized for nomore than 0.1 W.C. drop per 100 ft. of duct, and amaximum duct velocity of 2000 FPM.

Up to a maximum of two additional Slaved-ZoneDampers may be connected together with themain Zone Damper(s) for large zone air flow re-quirements. This design should be reserved onlyfor situations when it is not practical to use a singlelarge Zone Air Damper.

It is recommended that the Slaved-Zone Damper(s) shouldbe of the same size as the master Zone Damper. This in-sures that adequate air flow and minimum noise will occurat all damper positions.

Divide the total zone CFM required by the total number ofair valves to be used.

Using the maximum acceptable velocity for a branch duct(typically 1000-1500 FPM for minimal noise), go to the AirDamper Selection Data Chart below and find the quantityand size of Air Dampers that will deliver the required CFMas determined by the load program

Note: Compare the Zone and Slaved-Zone Damper

sizes selected against the branch duct sizes to

determine if the next size up or down will pro-

vide acceptable performance without requiringa transition fitting.

Order one OE510 Pressure Dependent Zone Damper ofthe size selected previously. Order one or two OE513Slaved-Zone Dampers as required, of the same size as theOE510 Zone Damper just selected. The Slaved-ZoneDampers will track and maintain the same damper positionas the master Zone Damper.

'HV.ULSWLRQThe OE518 Rectangular Damper is used inapplications where rectangular duct isspecified or required because of spacelimitations or job requirements. The Rec-tangular Damper utilizes opposed blades of

airfoil design for improved air flow control.The Rectangular Damper frame is made of.080 thick extruded aluminum. The bladesare also made of extruded aluminum.Blade pins are 7/16 hexagon shaped alu-minum fixed to a Celcon inner bearing ro-tating within a polycarbonate outer bearinginserted in the damper frame. The Damperlinkage is mechanically assembled andlocated in the damper frame . The linkagecomponents are constructed of aluminum,zinc and nickel plated steel. Blade gasketsare made of extruded EPDM material andare secured 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 damper framefor connection to the damper actuator. Thedamper shaft is shipped retracted into theframe area and must be adjusted to therequired length in the field.

0RXQWLQJThe Rectangular Damper should be

mounted in the ductwork according tostandard duct installation practices. Therectangular damper should be selected forthe nominal inside duct size (See Figure 3). All Rectangular Dampers are supplied with 1 flanges all arounddamper frame, making the overall damper width and height 2 larger than the nominal inside duct size thus pro-viding for external flange mounting to ductwork. The damper shaft is shipped retracted into the damper frame.Loosen the two nuts on the U-bolt that secures the damper shaft to the damper blade and adjust to length. It isrecommended that the shaft length be adjusted so approximately 4 of shaft extends beyond the inside of thedamper frame. Retighten the two nuts on the U-bolt that secures the damper shaft to the blade. After installationof the Rectangular Damper to the ductwork, it is recommended that insulation be applied around any non-insulated surface on the ductwork where the Rectangular Damper was installed.

Use a load program to determine the peak load for each zone. These calculations will be used in selecting theappropriate Rectangular Damper sizes. The Auto-Zone Systems utilize a typical low pressure duct design. To re-duce noise problems, duct pressures should not exceed 1 W.C.

Primary trunk ducts used with Auto-Zone systems should not be undersized. This is especially true of pressuredependent systems. With pressure independent systems this is not as critical. With larger trunk ducts, it is easierto assure 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 (-).

When space considerations or design criteria dictate, dampersmay be selected for other face velocities by using the multipli-ers listed in the notes associated with the table. Move acrossthe table and find the damper selection which will provide the

required CFM and fit within the ceiling area where the damperwill be located. Many size selections are possible for a givenCFM. Pressure drop across the damper is shown in parenthe-sis below the CFM.

tangular Bypass Damper is controlled bythe Auto-Zone System Zone Manager. TheZone Manager modulates the RectangularBypass Damper in response to the ductstatic pressure based on a signal receivedfrom a static pressure sensor located in themain system ductwork.

The Rectangular Bypass Damper Kit isused in conjunction with rectangular damp-ers for applications where rectangulardampers are specified or required becauseof space limitations or job requirements.

The rectangular dampers may be pur-chased from WattMaster or you may getthem from the supplier of your choice. Forproper control, WattMaster recommendsthe use of low leakage opposed bladedampers. The maximum allowable damperface area for the Rectangular BypassDamper Kit is 6 sq. ft. The Rectangular By-pass Damper Kit comes packaged with theDamper Actuator and Wiring Interface pre-mounted in a galvanized steel enclosure.Each kit is supplied with mounting hard-ware and installation instructions. For applications where CFM or space requirements dictate the use of more thana single bypass damper, up to 2 additional bypass dampers can be slaved together. No other components are

required. Each bypass is wired to the other bypass damper(s) by means of the Wiring Interface.

0RXQWLQJBefore 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.

connection to the actuator is by means ofa modular phone cable connector lo-cated on the actuator cover. The actua-tor is rated for 35 in-lb of torque. All ac-tuators are electronically protectedagainst overload. The angle of rotation is

mechanically limited to 95. When theend position of the actuator or damper isreached, the actuator automaticallystops. For adjustment purposes, thegears can be manually disengaged bypushing the manual override button onthe actuator cover.

0RXQWLQJThe actuator is mounted and adjusted inthe following manner:1. Turn the damper blade to its fully

closed position.2. With the manual override button de-

pressed, rotate the actuator clamp toabout 1/16 to 1/8 between the ac-tuator stop and the clamp, depend-ing on the damper seal design. Slidethe actuator over the shaft and fingertighten the nuts.

3. Slide the L-type anti-rotation bracket(supplied) up under the actuatorcenter cut-out on the back of theactuator. Secure the bracket with thesupplied self-tapping screws. Tightenthe two nuts on the actuator shaftclamp with an 8mm wrench to 3 to 5ft-lbs.

*Chart Notes:1. Use the resistance column to check the thermistor sensor while disconnected from the controllers (not powered).

2. Use the voltage column to check sensors while connected to powered controllers. Read voltage with meter set on DC volts.Place the "-"(minus) lead on GND terminal and the "+"(plus) lead on the sensor input terminal being investigated. If the voltageis above 5.08 VDC, the sensor or wiring is "open." If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.

The Duct Sensor Is Used For Sensing SupplyOr Return Air Temperatures. Location Of TheSensors Is Very Important In Order To ObtainAccurate Temperature Readings. TheFollowing Recommendations Should BeFollowed:

When Used As A Supply Air Sensor TheSensor Should Be Mounted In The Supply AirDuct As Close To The HVAC Unit As PossibleAnd Upstream Of The Bypass Damper (IfUsed) For Best Results. For Best Accuracy,Apply Insulation On The Outside Of TheDuctwork Over The Sensor. This Will HelpThermal Gradients From Affecting The Sensor.

The plastic housing on the sensor is electricallyconductive. Avoid contact with any electrical components.It is acceptable to mount the sensor on grounded sheetmetal such as ductwork, electrical panels, etc.

Use extreme care when mounting the sensor to avoiddamage to the plastic housing. Do not overtighten themounting screws! Do not use mounting screws which aretoo large for the holes!

Warning!

Warning!

When The OE271 Is Used As A DuctIt May Be Mounted To The

Ductwork Near The Static Pressure Pickup Tube. IfThe Sensor Is Mounted In This Manner, Away

From The Controller, The Modular Plug Must BeCut Off And 3-conductor 24 Gauge Minimum WireMust Be Butt Spliced To The Sensor Leads. TheController Has A Terminal Block Which IsParalleled With The Modular Jack To Allow WiringConnections. Total Wire Length Should NotExceed 100Ft. If Desired The Sensor May Also BeLocated Near The Controller, With The ModularPlug On The Sensor Directly Connected To TheMating Controller Jack. When This Method Is UsedTubing Must Be Run From The Sensor To TheStaic Pressure Pickup Tube. Tubing Should NotExceed 250 Ft. And Must Be Continuous WithoutAny Splices.

StaticPressure Sensor

When The OE271 Is Used As An AirflowFor VAV Applications It Should Be Mounted In TheVAV Box Control Enclosure Near The BoxController Board. The Modular Plug should be

Connected To The VAV Controller BoardConnection. Tubing Must Be Run From TheSensor to The Airflow Pickup Probe TubingConnection.

Sensor

1.) The OE271 Pressure Sensor Should BeMounted In A Vertical Position As Shown WithArrow Pointing Up. ( Tubing Connections PointingDown). If This Mounting Position Is Not Possible InYour Application, It May Be Mounted In A HorizontalPosition. When Mounted In A Horizontal PositionAccuracy Will Be Affected By Approximately 2% FullScale Null Shift Due To Diaphragm Gravity EffectError.
