120 / 24VAC

Some installers like to use one large 24VAC transformer to power several controllers. This is allowable as long as polarity is maintained to eachcontroller on the transformer circuit.

Usingseparate transformers also allows redundancy in case of a transformer failure. Instead of having 8 controllers inoperative because of a malfunctioningtransformer you have only 1 controller off line. If the installer does decide to use a large transformer to supply power to several controllers, thefollowing transformer and wire sizing information is presented to help the installer correctly supply 24VAC power to the controllers.

Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.

Each Zone Controller with actuator requires 10 VA @ 24VAC power. In the examples below we have a total of 8 Zone Controllers.

8 Zone Controllers @ 10VA each................ 8 x 10VA = 80VA.

The above calculation determines that our transformer will need to be sized for a minimum of 80VA if we are to use one transformer to power all thecontrollers.

Next we must determine the maximum length of run allowable for the wire gauge we wish to use in the installation. Each wire gauge below has avoltage drop per foot value we use to calculate total voltage drop.

18ga wire.................................0.00054 = voltage drop per 1’ length of wire16ga wire.................................0.00034 = voltage drop per 1’ length of wire14ga wire.................................0.00021 = voltage drop per 1’ length of wire

For our example we will use 18 gauge wire. York recommends 18 gauge as a minimum wire size for all power wiring.

Next use the voltage drop per foot value for 18 gauge wire from the list above and multiply by the total VA load of the 8 controllers to be installed.

0.00054 (Voltage drop per foot for 18 gauge wire) x 80VA controller load = Volts/Ft.

Meridian controllers will operate efficiently with a voltage drop no greater than 2 Volts. Divide the total allowable voltage drop of 2 Volts by the numberyou arrived at above and you have the maximum number of feet you can run the 18 gauge wire with an 80VA transformer with no more than a 2 Voltdrop at the farthest controller from the transformer..

2 (Volts total allowable voltage drop)=

0.0432 (Voltage drop per 1 ft. @ 80VA load)

Parallel circuiting of the wiring instead of wiring all 8 controllers in series allows for longer wire runs to be used with the same size wire (as shown inour examples below).

Warning: If polarity is not maintained, severe damage to the controllers may result. York recommendsusing a separate transformer for each controller in order to eliminate the potential for damaging controllers due to incorrect polarity.

0.0432

46.30 feet

It is often necessary for the installer to calculate and weigh the cost and installation advantages and disadvantages of wire size,transformer size, multiple transformers, circuiting, etc., when laying out an installation. No matter what layout scheme is decided upon, it is mandatorythat the farthest controller on the circuit is supplied with a minimum of 22 Volts.

Familiarize yourself with the installation manual and system wiring diagrams before installing!

1. Check to see if you have all the correct components for your installation.

2. Establish the location for the CommLink Interface first. This is where your communication cable will begin for the Plus,CV, & CV-EX systems. The CommLink is optional for the Basic system.

3. Layout your communication wiring. For Plus and CV-EX Systems there are two communication loops:

A. The Network Loop - This loop originates at the CommLink and interconnects Zone Managers or MiniLinkstogether.

B. The Local Loop – This loop originates at the Zone Manager or MiniLink. All controllers and the System Managerare connected to this loop.

4. Tip: Using the York color-coded and labeled Communication Cable insures a quality installation. It also makes yourinstallation much easier and less likely to have communications wiring errors!

5. Always refer to the Meridian Wiring Diagrams for specific wiring details. Communication cable must always beshielded – no exceptions!

6. Mount controllers in appropriate locations according to their operating specification.

7. Address controllers according to location and addressing instructions located in the system manual.

8. With no power connected, wire controller according to wiring diagrams and in accordance with local codes. Neverapply power until you have completed these procedures in accordance to all system instructions.

9. After completing all wiring connections, unplug the terminals for power and communications. Always unplug thecommunications loop first and then the power. When reconnecting the wiring, connect the power first and then thecommunication loop.

10. Continue step 8 until all devices have been wired and the power and communication terminals have been unplugged.

11. Install CommLink and power-up. At this point you are ready to begin commissioning the system. It is preferred, thoughnot necessary, to use a PC with Meridian software to assist in the commissioning process.

12. Start with the first controller on the communication loop or in multiple loop systems; start with the Zone Manager orMiniLink with the System Manager. Plug in the Communication terminal then plug in the Power terminal.

13. For Zone Controllers and CV Controllers observe the LED indicator for the blink codes as outlined in the troubleshoot-ing section of the manual. The blink code will first verify the address, then the operation. If the address is incorrect,reset the dipswitch, then reapply power to the controller.

14. After each controller is connected and completes its initialization sequence, use the PC or System Manager to verifycommunication to that device. If you cannot communicate, verify wiring, voltages, etc. in accordance with the trouble-shooting section in the system manual. Do not proceed to the next device until you are properly communicating withthe current device.

Continue this process until all controllers are connected and properly communicating.

By following the above steps and procedures, your installation will be much faster and trouble free. Remember that eachcontroller only contains one puff of smoke. Making sure that all wiring terminations and voltages are correct prior to apply-ing power to a controller will insure that you don’t use that one puff.

1.)24 VAC Must Be Connected So That AllGround Wires Remain Common.

2.)All Wiring To Be In Accordance With Local AndNational Electrical Codes And Specifications.

3.)AllCommunication Wiring To Be 2 Conductor TwistedPair With Shield. Use Belden #82760 Or Equivalent.

Required VA ForTransformer

For Wetbulb Controller= 20VA Max.

Suggested Wetbulb Economizer SettingsThe Wetbulb Temperature value is 65 F forEconomizer Enable. The Mechanical CoolingLockout setpoint is 60 F. The Economizer Enable WetbulbTemperature should be set lower than the MechanicalCooling Lockout Setpoint. If you allow the Economizer WetbulbEnable Setpoint to drop below the Mechanical Cooling LockoutSetpoint the unit can enter a mode where cooling is required inthe space but both the mechanical cooling and the economizerare disabled at the same time. Basically, you can economicallycool outside air that is below 78 F if the wetbulb temperature is65 F or lower. In the case of the Meridian system, theEconomizer is always considered the first stage of cooling. Ifthe outside air is above 78 but the wetbulb temperature is stillenabling the economizer, the outside air dampers willimmediately move to the full 100% open position. This allowsthe mechanical cooling to activate after a short two minutedelay and begin cooling the low moisture outside air rather thanthe high moisture content of the return air.

If the wetbulb temperature rises above the Economizer EnableSetpoint while the economizer is currently active and themechanical cooling is active, the economizer will be returned toits minimum position and the unit will maintain strictlymechanical cooling.

Be sure the chip you have selected to replace is asocketed chip. Not all driver chips on the boardsare field replaceable. Only socketed chips may beremoved and replaced in the field. All other chipsthat are not socketed will require sending the boardto the YORK factory for repair.

Once you have determined that thechip needing replacement is indeed a socketed chipplease proceed in the following manner.

Remove the communications loop connector andthen the 24VAC power connector on the controllerbefore attempting to change any components.

will occur if components are removed orinstalled with power applied.

If you are unsure how to safely remove the chip orabout the correct pin placement, please consult thefactory before proceeding.

Use extreme care to avoid inserting the screwdriveror I.C. Puller under the socket. You must insert the tipof the screwdriver or ends of the I.C. Puller betweenthe body of the chip and the chip socket.

Each chip be installed with Pin 1 in the correctlocation. Installing the chip “backwards” will in mostcases destroy the device when power is reapplied.

Pin 1 can be located by looking for the notch in the endof the chip. Pin 1 on "some" chips is identified with a dot.

Be certain that pins are lined up in the socketbefore pressing the chip in. Failure to properly lineup the pins will result in damage to the chip.This is a common error -

Only after confirming that the chip has been correctlyinstalled with Pin 1 in the proper position and that thepins are lined up and none are bent or out of the socket,should communication or power wiring be reconnectedto the board. Tp prevent possible damage alwaysreconnect the power wiring first and then thecommunication wiring.

If you try toremove a chip that is not socketed it will destroythe circuit board.

DAMAGE

Damage to the board caused by failure to correctlyremove or install the chip is not covered by theYORK warranty.

VERY BE CAREFUL.
