��The Meridian CV control system is designed to con-trol up to 30 single zone, constant volume HVACunits. For systems with more than 30 single zoneconstant volume units, the CV-EX control system isavailable which will allow 60 single zone units on thesystem, and 30 more with each CV-EX Loop Expan-sion Kit. Up to two CV-EX Loop Expansion Kits canbe added for a total system maximum of 120 singlezone constant volume units being controlled on thesystem. Each CV controller on the CV system oper-ates stand alone and shares common data, such asoutside air temperature, over a communicationsnetwork.

The System Manager is a central operators interfaceto all controllers on the network. All system vari-ables, setpoints, and values can be viewed andmodified from one convenient location. Menu drivenprogramming using English language descriptors,make the Meridian CV easy to set up and operate.

The System Manager is password protected to pre-vent unauthorized access to the control system.

The CommLink interface provides an intelligent, highspeed computer/modem interface to the CV system.A computer and/or Remote Link can be connectedfor on site or remote monitoring (not required for thesystem to operate). MeridianView, a Windows™based software program, provides a user friendly,full function program for system set up, status, callout alarm capability, and trend logging.

��

• All control devices are 24 VAC and can be pow-ered from common or individual transformers.

• CommLink - 24 VAC (Plug-in transformer in-cluded)

• Communications - RS-485/9600 Baud - DaisyChain Configuration - Twisted Pair/Shieldedwire

��The Meridian 2ZRC0247000224 and the2ZRC0247000424 CV Controllers are usedfor controlling a constant volume HVACunit. The 2ZRC0247000224 is the Fahren-heit version and the 2ZRC0247000424 isthe Celsius version of the controller. TheCV Controller operates stand-alone andshares common data, such as outside airtemperature, over a network. A SystemManager is connected to the CV Controllerto provide a central operators interface toall CV Controllers on the network. A Me-ridian CV system provides an excellent al-ternative to installing multiple programma-ble thermostats to control constant volumeHVAC units. CV Controllers are designedwith room temperature, room setpoint ad-just, outside air temperature, discharge airtemperature and auxiliary alarm inputs.Relay outputs provided are; fan (continuousor cycling), four stages of heating/cooling(user configurable) and economizer control(0-10VDC output, full modulating). An in-ternal seven day schedule function is alsobuilt in to each CV Controller.

�� The CV Controller is provided with an inte-gral backplate for mounting inside of acontrol enclosure. It is recommended thatthe CV Controller is mounted in the HVACunit control enclosure, or in a control enclo-sure in the building equipment room. An optional factory control enclosure for the CV Controller is available.

��The York Meridian 2ZCP004703124CommLink II Communications Interfaceallows user access to any controller in theMeridian system. It is configurable forsingle loop or multiple loop applicationsby a simple jumper switch setting on thecircuit board. The CommLink II comespackaged in an attractive beige coloredplastic enclosure. The CommLink II ispowered by a small wall mounted plug-intransformer that is included. Locally, anoptional on-site computer may be con-nected to the CommLink II for direct ac-cess to system control parameters. Re-mote access is obtained via an optionalRemote Link (modem) which is con-nected with the CommLink II Communi-cation Interface. With the Remote Linkinstalled, the CommLink II may be config-ured to call a number, if an alarm condi-tion occurs. With the Remote Link optioninstalled the system could be dialed andmonitored from a remote location by aPC. Computer and modem cables (6ftlong) are provided with the CommLink II.

�� If an on-site computer is to be used fordirect connection and monitoring of thesystem, the CommLink II should be lo-cated near the computer terminal tomonitor the system. If no on-site com-puter is to be used, locate the CommLinkII near the phone line jack for ease ofconnection to a the Remote Link (mo-dem). If for any reason you use cables ofgreater length than those provided withthe CommLink II (6 ft. long) be sure thecables that connect the CommLink II tothe modem and the CommLink II to theon-site computer do not exceed twenty-five feet in length.

��The Meridian 2ZRE0047001024 - 8 RelayOutput Modular Expansion Board is usedin conjunction with the CV-C ControllerBoard to allow for additional stages ofheating and cooling. The Relay Expan-sion Board provides 8 relay outputs forpilot duty switching control.

The Relay Expansion Board connects tothe CV-C Controller by means of amodular cable provided with the RelayOutput Expansion Board. Quick ConnectTerminals for connection of 24VAC powerare provided on the Relay Output Expan-sion Board for field wiring to a 24VACpower source. Quick connect terminalsare also provided for connection of fieldwiring to the relay outputs.

The relay outputs are N.O. contacts withtwo common terminals. All outputs andthe relay common are electrically isolatedfrom all other circuitry on the board. Allrelay outputs are supplied with transientsuppression devices across each set ofcontacts to reduce EMI and arcing. Therelay output contacts are rated for pilotduty control of a maximum of 2 Amps @24 VAC or 24 VDC.

�� The Meridian Relay Output ExpansionBoard is supplied mounted on a plasticSnap Track channel. The Snap Trackchannel has two mounting holes whichare used to field mount the board with theprovided screws.

��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.

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.
