The Meridian Basic control system converts a singlezone HVAC unit into a variable air volume/variableair temperature multiple zone system. The micro-processor based Zone Manager calculates theheating 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 ofheating, 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 Me-ridian Basic system instead of installing multipleHVAC units to accommodate multiple zones. TheMeridian Basic system is versatile and can be usedwith any 3-40 ton HVAC unit. It controls a variety ofterminal units including single duct pressure de-pendent or pressure independent zone damper.

User friendly, menu driven, fill in the blank pro-gramming, makes the Meridian Basic easy to set upand operate without the need for specialized training.

MeridianView, a Windows based color graphic soft-ware package is available at no additional charge.The optional CommLink II must be ordered andconnected to a PC in order to use the software foron-site control and monitoring. If remote monitoringand control is required, an optional Remote Link(Modem) must be ordered ..

The Meridian 2ZMO004700224 and the2ZMO004700324 Basic Zone Managers aremicroprocessor based HVAC unit controllers.The 2ZMO004700224 is the Fahrenheit ver-sion and the 2ZMO004700324 is the Celsiusversionn. The Zone Manager calculates theheating and cooling requirements for eachzone based on real time information receivedfrom the Zone Controllers. It then controls theHVAC unit to provide the appropriate amountof heating, cooling, and ventilation to satisfyeach zones requirements. The Zone Manageralso controls a bypass damper which modu-lates the bypass airflow at the HVAC unit, inorder to maintain proper duct static pressure.One Zone Manager is required for each multi-ple zoned HVAC unit that is to be part of thebuilding HVAC system. Each Zone Managercan accommodate up to 16 zones.

The Zone Manager keypad & display provide acentral operators interface to all controllers onthe network. All system variables, setpoints,and values can be viewed and modified fromone convenient location. Menu driven pro-gramming makes the Meridian Basic systemeasy to set up and operate. The Zone Man-ager is password protected to prevent unau-thorized access to the system.

The Zone Manager is designed to be mountedindoors on a flat surface. Typically, the Zone Manager is mounted on a wall in the building managers office, orlocated on the wall of an equipment room or other location that prevents access by unauthorized personnel.

The 2ZBD00470xxxx Bypass Damper as-sembly, consists of a round air valve, actua-tor and bypass wiring interface card mountedin the enclosure.

The Bypass Damper controls duct staticpressure to insure proper system airflow.The Bypass Damper is controlled by the Me-ridian System Zone Manager. The ZoneManager modulates the Bypass Damper inresponse to the duct static pressure basedon a signal received from a static pressuresensor located in the main system ductwork.

All Bypass Dampers are tested and certifiedin accordance with ARI standard 880. An ARIlabel is affixed to all units.

The Bypass Damper Assembly should bemounted according to standard duct installa-tion practices with airflow direction as shownin the illustration above. After installation ofthe Bypass Damper in the ductwork, insula-tion should be applied around any remaininguninsulated surface on the air valve inlet and outlet. The Bypass Damper should be mounted so the control enclo-sure is positioned to the left or right side of the ductwork with the control enclosure in a vertical plane. Do notmount the Bypass Damper Assembly with the control enclosure on the top or bottom of the ductwork. Adequateclearance should be maintained between the control panel and any obstruction to allow for removal of the controlpanel cover and access to the controls.

Bypass & Slave Interface


Because the zones in a Meridian 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 whensizing 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 Meridian 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.

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

Compare the Bypass Air Damper size selectedagainst the bypass duct size to determine if the nextsize up or down will provide acceptable performancewithout 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 BypassDamper. 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 2ZMD00470xxxx series Pressure De-pendent Zone Damper for Fahrenheit op-eration consists of a round air damper,zone controller, and actuator. An optionalauxiliary relay board (2ZRE0047000024) isavailable for control of auxiliary heat and/orcontrol of series or parallel flow fan terminalunits.

The Zone Controller (2ZC0047000024) ismicroprocessor based and communicateswith the Zone Manager on the Meridiannetwork communications loop. The ZoneController monitors the space temperatureand allocates the proper airflow into its as-signed space to achieve the desired com-fort and ventilation levels.

Pressure Dependent Zone Dampers areused in air conditioning systems that do notrequire pressure independent airflow con-trol. If your system requires pressure inde-pendent control of the airflow, see the“2ZMD00471xxxx series - Pressure Inde-pendent Zone Damper - Fahrenheit” datasheet for the correct specifications.

All Zone Dampers are tested and certifiedin accordance with ARI standard 880. An ARI 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.

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

Primary trunk ducts used with Meridian sys-tems should not be “undersized”. This is es-pecially 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 noisein 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.

Zone Damper - Celsius


The 2ZMD00471xxxx series Pressure Independ-ent Zone Damper for Fahrenheit operation con-sists of a round air valve, zone controller, actua-tor, airflow sensor and a crossflow air pickupprobe. An optional auxiliary relay board(2ZRE0047000024) is available for control of aux-iliary heat and/or control of series or parallel flowfan terminal units.

The Zone Controller (2ZC0047000024) is micro-processor based and communicates with theZone Manager on the Meridian controller networkcommunications loop. The Zone Controller moni-tors the space temperature and allocates theproper airflow into its assigned space to achievethe desired comfort and ventilation levels.

The Pressure Independent Zone Damper is usedin systems that require pressure independentairflow control. If your system does not requirepressure independent control, please see the“2ZMD00470xxxx series - Pressure DependentZone Damper - Celsius” data sheet for the correctspecifications.

All Zone Dampers are tested and certified inaccordance with ARI standard 880. An ARI labelis affixed to all units.

The 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 with the control enclosure on the top or bottom of theductwork. Adequate clearance should be maintained between the control panel and any obstruction to allow forremoval of the control panel cover and access to the controls.

The Meridian 1ZRD00470xxxx Series Rectan-gular Damper is used in applications whererectangular duct is specified or required be-cause of space limitations or job requirements.The Rectangular Damper utilizes opposedblades of airfoil design for improved air flowcontrol. The Rectangular Damper frame is madeof .080 thick extruded aluminum. The blades arealso made of extruded aluminum. Blade pins are7/16” hexagon shaped aluminum fixed to a Cel-con inner bearing rotating within a polycarbonateouter bearing inserted in the damper frame. TheDamper linkage is mechanically assembled andlocated in the damper frame . The linkage com-ponents are constructed of aluminum, zinc andnickel plated steel. Blade gaskets are made ofextruded EPDM material and are secured withinan integral slot on the blade. Jamb seals are ofextruded TPE material for low leakage throughthe damper when closed. The control shaft is1/2” diameter hexagon shaped rod and can beextended 9” past the damper frame for connec-tion to the damper actuator. The damper shaft isshipped retracted into the frame area and mustbe adjusted to the required length in the field.

The Rectangular Damper should be mounted inthe ductwork according to standard duct instal-lation practices. The rectangular damper shouldbe selected for the nominal inside duct size (SeeFigure 3). All Rectangular Dampers are supplied with 1” flanges all around damper frame, making the overalldamper width and height 2” larger than the nominal inside duct size thus providing for external flange mounting toductwork. The damper shaft is shipped retracted into the damper frame. Loosen the two nuts on the U-bolt thatsecures the damper shaft to the damper blade and adjust to length. It is recommended that the shaft length beadjusted so approximately 4” of shaft extends beyond the inside of the damper frame. Retighten the two nuts onthe U-bolt that secures the damper shaft to the blade. After installation of the Rectangular Damper to the duct-work, it is recommended that insulation be applied around any non-insulated surface on the ductwork where theRectangular 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 Meridian 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 Meridian 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 therequired 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.

The patented design of the York Meridian RoomSensor provides accurate sensing of the roomtemperature. Its design allows for flush wallmounting yet rejects the influence of surface andinternal wall temperatures. The Room Sensor’sattractive styling and off white casing color make itsuitable for most building decors. If interior deco-ration requires, the Zone Sensor casing can alsobe painted or wall papered without affecting thesensor's performance. Room Sensors are avail-able in 4 different configurations:

• 2ZTS004704024 - Sensor Plain• 2ZTO004704024 - Sensor with Setpoint

Adjustment• 2ZTA004704124 - Sensor with Override• 2ZTB004704124 - Sensor with Setpoint

Adjustment and Override

The Room Sensor Plain and Room Sensor withOverride, require (2) wires to be connected fromthe controller to the sensor. The Room Sensorwith setpoint adjustment and Zone Sensor withSetpoint and Override options, require 3 wires beconnected to the sensor. Twisted cable is rec-ommended for wiring of all Room Sensors. Wiringshould not be run in conduit with other AC linevoltage wiring, or with any conductors carryinghighly inductive loads. Most applications do notrequire shielding.

The Room Sensors are designed to be mounted on a vertical, 2” x 4” electrical box recessed in the wall. If the wallcannot be penetrated, a plastic surface mount box such as those made by Wiremold, may be used to mount thesensor to the wall surface.

*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.

Notes:

In Order To Obtain Accurate Static Pressure ReadingsThe Static pressure Pickup Probe Should Be MountedPer The Following Recommendations:

1.)The Probe Should Be Mounted In a Straight SectionOf Ductwork Approx. 2/3 The Length Of the Supply Duct,Downstream Of The HVAC Unit.

2.)The Probe Should Not Be Mounted Less Than 3 DuctDiameters Downstream Or Not Less Than 2 DuctDiameters Upstream Of Any Elbow or Takeoff.

See The Systems Installation And Operation Manual ForOther Design Considerations And RecommendationsRegarding Static Pressure Pickup Tube Location.

Caution!

1.)The Static Probe Is Supplied With A 14“ Length OfTubing For Connection To The Static PressureSensor. The Static Pressure Sensor Is Designed ToBe Mounted Adjacent To The Location Where TheStatic Pickup Tube Is Mounted And Wired Back ToThe Controller Board. The Static Pressure SensorCan Also Be Mounted Close To The Controller BoardAnd Tubing (By Others) Routed From The Sensor ToThe Static Pickup Probe. Be Sure Not To Kink TheTubing Between The Static Pickup Probe And TheStatic Pressure Sensor.

Warning!

Warning!

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

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