Networked Multiple Loop - Computer Connection With IP-Link
Component & System Wiring12
General Information
The WattMaster VAV system components can be configured into dif-ferent types of systems depending on the type and number of control-lers required. It is a good idea to become familiar with the types ofsystems and their architecture by reading the information in this sectionand looking at the configuration diagrams in the System Configura-tions Installation & Commissioning section of this manual. The infor-mation below is designed to help you understand how the system com-ponents integrate with each other and the available configuration op-tions.
System Types
Two different system configurations are available depending on the typeand number of controllers that you have on your system.
1. Networked Single Loop(See Pages 6 Through 8 For Connection Diagrams)
2. Networked Multiple Loop(See Pages 9 Through 11 For Connection Diagrams)
System Type Definitions
Networked Single LoopThe Networked Single Loop system, as its name implies, consists of asingle communications loop. The system can consist of the followingcontrollers and devices.
1. A single WMVAV controller used as a VAV controller andit’s associated VAVBOXcontrollers. Other WMVAVcontrollers used for constant volume units and/or and Add-on Devices may also be connected as long as the total of allcontrollers on the loop does not exceed 59. Only one VAVcontroller with it’s VAVBOX controllers can be installedper loop. If more than one VAV controller with VAVBOXcontrollers is required, you must have a separate loop foreach.
This system requires one CommLink communications interface andone MiniLink Polling Device. Programming and status monitoring areaccomplished by the following methods.
1. By using an operators interface. This can be either aModular System Manager, a Modular Service Tool or bothdevices. The System Manager or Modular Service Toolcan connect to any controller on the local loop.
2. A computer interface can also be used in conjunction withthe other operators interfaces listed above, or by itself. Thisrequires a personal computer with the Prism computer frontend software installed. The PC connects to the CommLinkvia a supplied cable.
Networked Multiple LoopThis Networked Multiple Loop System consists of two or more loops,each being called ‘Local Loops’, with one ‘Network Loop’ that ties the“Local Loops” together. Each of these local loops can consist of thefollowing controllers and devices.
1. A series of WMVAV controllers for constant volume unitsand/or Add-on devices without any VAVBOX controllers.Up to 59 controllers may be connected on the loop in thismanner.
2. A single WMVAV controller used as a VAV controller andits associated VAVBOX controllers. Other WMVAVcontrollers used for constant volume units and/or and Add-on Devices may also be connected as long as the total of allcontrollers on the loop does not exceed 59. Only one VAVcontroller with its VAVBOX controllers can be installedper local loop.
To form the Networked Multiple Loop System the following networkdevices are required.
1. A MiniLink Polling Device is required per loop (LocalLoop). This allows the controllers to share information thatis broadcast from one controller to all controllers on thatlocal loop and also provides alarming and trend loggingcapabilities.
2. One CommLink is required for the entire system. It resideson the Network Loop and allows for communicationsbetween all the local loops and provides for globalbroadcasts to all controllers on the entire system.
Programming and status monitoring are accomplished by one or moreof the following methods.
1. By using an operator interface. This can be either aModular System Manager, a Modular Service Tool or bothdevices. The System Manager or Modular Service Tool canconnect to any controller on any “Local Loop” on theentire system.
2. A computer interface can also be used in conjunction withthe other operators interfaces listed above, or by itself. Thisrequires a personal computer with the Prism computer frontend software installed. The PC connects to the CommLinkvia a supplied cable.
Network Communications Devices
MiniLink Polling Device1. This device is required for all Networked Single loop
systems.
2. One of these device is required on each local loop of allNetworked Multiple Loop systems
CommLink1. One CommLink is required on all Networked Single Loop
or Multiple Loop Systems
2. Up to 60 local loops can be connected to the CommLink
Installation Procedures
The installation procedures that follow are based on recommended meth-ods of wiring connection and controller installation. Installation proce-dures vary depending on the which Networked system you are install-ing. The system you are installing could be “Networked Single Loop”or a “Networked Multiple Loop” system. The Networked Systemsalso have installation variations based on the type of components youare installing for that system. The following information explains theprocedures for all of these systems. Please find the system and compo-nents that closely match your system and follow the outlined proce-dures.
Systems Overview
Component & System Wiring 13
Networked Single Loop Systems
See the “Networked System - Single Loop Wiring” on pages 6 through8 of this manual for detailed wiring information. Also see page 16 forwire and transformer sizing information. You should review these dia-grams before attempting connections or powering up the controller orinterface devices.
1. Connect all WMVAV or Add-on Device controllers in adaisy chain or star ring format by connecting from eachcontroller’s communication terminal block to the next using18 gauge, 2 conductor shielded cable. Install a separate 24VAC, transformer for each controller and wire from eachcontroller’s power terminal block to its transformer using18 gauge minimum, 2 wire cable for power. See Wire andTransformer Sizing section on page 16 for detailedtransformer and wire sizing information. Observe polarityon all board power wiring. Install a separate 24 VAC, 6 VAminimum, transformer for each VAVBOX controller on theloop and wire from each controller’s power terminal blockto its transformer using 18 gauge minimum, 2 wire cable.Observe polarity on all boards! As an alternative, a singletransformer that connects to all VAVBOX controllers mayalso be used. It must be sized to handle the minimum loadof 6 VA per VAVBOX controller connected to it. Whenusing this method, the polarity of all wiring between thetransformer and the VAVBOX controllers is extremelycritical and must be maintained to prevent damage toall boards connected! See the wire and transformer sizinginformation on page 16 of this manual for completewire and transformer sizing information.
Warning: If polarity between controllers is not maintained,severe damage to the controllers may result.WattMaster recommends using a separate transformerfor each controller in order to eliminate the potentialfor damaging controllers due to incorrect polarity.
2. Using 18 gauge 2 conductor shielded cable, connect fromthe WMVAV controller’s 3 wire communicationsconnector to the MiniLink PD’s 3 wire communicationsconnector marked “Local Loop”.
3. Connect 2 conductor shielded cable from theMiniLink PD’s 3 wire communications terminal blockslabeled “Network Loop” to the CommLink’s 3 wirecommunications terminal block located on the back of theCommLink. Find the 110 VAC/24 VAC power supplyfurnished with the CommLink and connect the 2 strippedwire leads to the 24 VAC terminals on the back of theCommLink. The CommLink’s internal jumper must be setto “Multiple” for all WattMaster VAV systems. See page 45of this manual for complete CommLink wiring and jumpersetting information. After determining all wiring andjumper settings are correct, connect the power supply plug-in transformer to a 110 V receptacle.
4. Install a 24 VAC, 6 VA minimum, transformer for theMiniLink PD and wire it to the 24 VAC power terminalblock on the MiniLink PD using 18 gauge minimum, 2wire cable. See page 46 of this manual for completeMiniLink PD wiring diagrams and instructions.
5. When the Modular Service Tool is to be used forprogramming and monitoring of the controllers it can beconnected to the WMVAV controllers using the suppliedcable with DIN connectors on both ends. The DINconnector on the WMVAV controller is located near thecommunications terminals. To connect the Modular ServiceTool to a VAVBOX controller first unplug the 3 wirecommunication terminal block from the VAVBOXcontroller. Connect the DIN to terminal adapter terminalend to the communication terminals block socket on theVAVBOX controller then connect the DIN connector sideof the adapter to the Modular Service Tool cable DINconnector. See page 44 of this manual for completeModular Service Tool connection diagrams andinstructions.
6. The Modular System Manager comes supplied with a 12foot modular cable pigtail with a modular connector on oneend and stripped wires on the other. Plug the modularconnector end into the System Manager modular connector.Run 18 gauge, 2 conductor shielded cable forcommunications from the MiniLink PD or any controlleron the local loop by connecting one end of the controller’sor MiniLink PD’s 3 wire “Local Loop” communicationsterminal block to a junction box located within 12 feet ofthe System Manager. Run 18 gauge, 2 wire, power wiressupplied by a separate 24 VAC, 6 VA minimum transformerinto the junction box. Splice the stripped modular cableends from the System Manager to the communications andpower wire inside of the junction box using solidconnections made with wire nuts or butt-splice connectors.See Modular System Manager wiring on pages 42 and 43of this manual for wiring color coding and complete wiringinstructions. The Modular System Manager MUST alwaysbe connected on the “Local Loop”, never the “NetworkLoop”.
Networked Multiple Loop Systems

24VAC Power - Transformer & Wire Sizing Considerations For VAVBOX Controllers

120 / 24VAC
Some installers like to use one large 24VAC transformer to power several devices. This is allowable as long as polarity is maintained to each device onthe 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 devices, the followingtransformer and wire sizing information is presented to help the installer correctly supply 24VAC power to the devices.
Following is a typical example to help the installer to correctly evaluate transformer and wiring designs.
Each VAVBOX Controller requires 6 VA @ 24VAC power. In the examples below we have a total of 10 VAV Controllers.
10 VAVBOX Controllers @ 6VA each................ 10 x 6VA =60VA.
The above calculation determines that our transformer will need to be sized for a minimum of 60VA if we are to use one transformer to power all thecontrollers. We will use a 75 VA transformer, as this is a readily available size that meets our VA load requirements.
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. WattMaster 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 10 controllers to be installed.
0.00054 (Voltage drop per foot for 18 gauge wire) x 60VA controller load = Volts/Ft.
WattMaster VAVBOX controllers will operate efficiently with a voltage drop no greater than 2 Volts. Divide the total allowable voltage drop of 2 Volts bythe number you arrived at above and you have the maximum number of feet you can run the 18 gauge wire with an 75 VA transformer with no morethan a 2 Volt drop at the farthest controller from the transformer..
2 (Volts total allowable voltage drop)= 61.73
0.0324 (Voltage drop per 1 ft. @ 60VA load)
Parallel circuiting of the wiring instead of wiring all 10 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 devices may result. WattMaster Controls recommendsusing a separate transformer for each device in order to eliminate the potential for damaging controllers due to incorrect polarity.
0.0324
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 and that the polarity is maintained to all controllers connected to thetransformer.

This output is DC voltage. Ourcontrollers will accept DC voltageif the voltage is above 28 VDC.
Note:
NOTE: This board goes between the supply transformerslow voltage output and the controllers low voltage input.WattMaster Controllers do not like to see more than28 VAC on their input side. When the line voltage to thetransformer is too high, generally the output side of thetransformer (low voltage) is too high, thus requiring thisOver Voltage Board.

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 WattMaster 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 theWattMaster warranty.
MUST

VERY BE CAREFUL.

Thermistor Sensor Testing Instructions
Use the resistance column to check the thermistor sensor while discon-nected from the controllers (not powered). Use the voltage column tocheck sensors while connected to powered controllers. Read voltage
with meter set on DC volts. Place the “-”(minus) lead on GND terminaland the “+”(plus) lead on the sensor input terminal being investigated.
If the voltage is above 5.08 VDC, then the sensor or wiring is “open.”If the voltage is less than 0.05 VDC, the sensor or wiring is shorted.
Sensor ChecksThe following sensor voltage and resistance tables are provided to aidin checking sensors that appear to be operating incorrectly. Many sys-tem operating problems can be traced to incorrect sensor wiring. Besure all sensors are wired per the wiring diagrams in this manual.
If the sensors still do not appear to be operating or reading correctly,check voltage and/or resistance to confirm that the sensor is operatingcorrectly per the tables. Please follow the notes and instructions beloweach chart when checking sensors.
