The screen shown above will appear asking you to enter a unit I.D.# (controller address). Put in the ID# of the controller you wish to communicate with then press the “ENTER” key.

If this is Multiple Loop Network System the Unit ID is actually two separate numbers, combined into one value. The first part of the number contains the Loop Address at which the controller is located. The second part of the number contains the actual controller address. See Examples #1 & #2 below.

EXAMPLE #1

You would like to view the 3rd controller on the 5th loop. Enter “503” as the Unit ID.

EXAMPLE #2

Y ou would like to view the 12th controller on the 24th loop. Enter “2412” as the Unit ID

EXAMPLE #3

You would like to view the only controller on the loop. Enter 1 as the Unit ID. No loop number is required since there is only one loop.

Hit the “Enter” key after entering the unit ID. If you are using the Modular Service T ool you will be taken directly to the first screen for the operation you are trying to program.

Modular System Manager

System Manager Initialization Screens

When the System Manager is powered up, the first screen displays the current version of the software installed in your System Manager and whether your system is configured for Network or Stand-Alone operation. On a Networked System, all controllers on the communications loop are available for programming by entering their loop address (ID).

If the System Manager is configured for Stand-Alone operation, only the HVAC unit controller that the System Manger is connected to is available for programming. The Stand-Alone feature is only used for servicing and testing. For normal operation the System Manager must be configured for Network mode.

63) Network System Enter Mode Of Op:.xx

As previously described the System Manager must be configured for the correct mode of operation for your system. Again, there are 3 modes of operation available for the W attMaster VAV System. They are “Stand Alone Mode”, “Multiple MGRS Mode” or “Network Mode”.

Look at the bottom line of the display as mentioned in the previous paragraph and determine which one your System Manager is currently set for. If you have a single System Manager for your entire system, then you need to operate in “Network Mode” and the first two characters on the bottom line of the display should be “NM”. If you have multiple System Managers on your system then you need to operate in “Multiple MGRS Mode” and the first two characters on the bottom line of the display should be “MM”. The System Manager should never be set to “Stand-Alone” mode unless you have been instructed to configure this setting by WattMaster Technical Support.

If your display indicates a different mode than the one you need, press the “Enter” key and the following screen will appear.

For “Multiple MGRS Mode” enter the address at which you want this particular System Manager to be set. When multiple System Managers are used on a local loop, each must be set with a unique address different from any other device on that loop. You must perform this same operation again for each System Manager installed. If you want one of these System Managers to be able to indicate alarms and overrides for the entire system you must enter “63” for “Network Mode” on that particular System Manager.

For “Network Mode” (or as explained above for Multiple System Managers when one is to be set to indicate alarms and overrides) enter “63”.

For “Stand Alone Mode” enter “0”.

Once you have the correct number per the display above displayed, press the ENTER key. The following screen will appear telling you that you have changed the system mode. Press any key on the keyboard to exit this screen.

You Have Changed The System Manager Mode Press Any Key To Continue

System Manager NM & MM Mode Loop Search

When the System Manager is configured for Network Mode a loop search must initially be performed for the System Manager to recognize alarms or overrides. Also, when you have a system that has multiple System Managers and you have one of the System Managers set to (63) Network Mode for alarm and override indication, you must also perform a loop search for that System Manager. This allows the System Manager to be aware of all alarms and overrides for all local loops on the entire system. .

Note: The Loop Search function is only required when using

the System Manager(s), not the Modular Service Tool.

To access the Loop Search screen, do the following. From the main menu screen press enter to display the following screen.

1) Set Time & Date

2) Communications

->) Next Menu ESC) Exit Menu

Press the “Next” arrow key. The following screen will be displayed.

The screen will display the number of loops found on your system. The information will be saved into the System Manager’s memory. No further loop searches will be required unless an additional MiniLink Polling Device is added to the Network System.

System Manager Alarm Search

The System Manager can be used to search for all active alarms on the system. The MiniLink PD must be configured to allow for “Alarm Polling” for each controller that alarming is desired on for this function to work. See the MiniLink PD programming section of this manual for setting information. Press the “Alarm” key. The Unit Selection screen below will be displayed. Enter the Unit ID of any unit on the system and press “Enter”. This is the unit ID of where the alarm search begins. The entire system is searched from this point.

System Manager Passcodes

THIS ACTION REQUIRES PASSCODE CLEARANCE Enter Passcode: xxxx

The System Manager has two levels of user access. Level 1 users are limited to viewing or changing the Time, Date, Operating Schedules and Heating and Cooling Setpoints. Level 2 users have complete system access. Any status or setpoint field can be read or reset from the System Manager.

This screen allows you to enter new Level 1 or Level 2 passcodes. The actual digits in your passcodes are never displayed. An “X” is used as a place holder for each digit entered. Passcodes must always be four digits in length, so the usable range of numbers is 1000 to 9999.

Caution: If you change the Level 2 passcode and cannot

remember what it is, you will be locked out of your system!

Modular Service Tool

The Modular Service Tool is very similar to the System Manager in its operations as stated previously. Two exceptions to this are that the Service Tool unlike the System Manager does not check the entire system when performing an “Alarm” or “Override” search and it does not have any passcoding capability.

Note: When the Alarms or Overrides buttons are pressed on

the Modular Service Tool it will search only the loop number of the unit ID that has been entered, therefore each local loop must be searched individually to access all alarms or overrides on the system.

These two levels of passcodes are programmable by any Level 2 user. The default Level 1 passcode is “111 1” and the default Level 2 passcode is “2222.”

WMVAV Config ID 59 Stage Configurations Rly xx: Not Used Press “0” to Change

The following 20 screens allow you to set the four relays on the WMVA V controller board and up to sixteen additional relays when relay expansion board(s) are used.

The first relay on the WMVAV controller is always reserved for the Supply Fan. The remaining four relays on the main board and the additional sixteen relays on the expansion relay modules can be configured by pressing the “0” key to change the relay to the desired configuration. Available relay configurations are listed in the table that follows.

The WMVAV controller does not require that you start configuring your heating or cooling stages first and it doesn’t require that you utilize consecutive relays until all heating or cooling stages have been defined. All relays can be used for any of the above options in any order you desire. This method allows the greatest flexibility in the field, but it requires close attention to the wiring of the heating and cooling stages to prevent incorrect and possibly harmful operation.

The controller assumes there will only be one relay configured for Morning Warm-up Mode although it doesn’t prevent multiple relays from being selected. Since this relay is used to send a signal to VAV boxes to drive to their maximum airflow position, redundant relays are not required.

Relays #2 through #21 can be individually configured. This should be enough to handle up to 8 stages of heating and 8 stages of cooling on large HVAC units. Only the heating and cooling relays can be configured with multiple outputs. If any other option is selected more than once, it will simply activate redundant relays but no multiple staging will occur.

The soak multiplier is used to increase the normal optimal start calculation whenever the building has been in the unoccupied mode for 24 consecutive hours or more. If you used a 1.5 multiplier and the optimal start had calculated a 30 minute pre-start, the soak multiplier would add an additional 15 minutes to the pre-start for a total of 45 minutes (1.5 x 30).

If you are using the internal scheduling capability of the WMVAV controller, set the schedule hours and holiday periods from the menu shown above. You can also force the unit to operate continuously in occupied or unoccupied mode by selecting the Schedule Override menu item and entering the desired command.

If you are using an external contact closure to signal the occupied mode, you must access the Week Schedule screens and set all start and stop times to zero to prevent the internal schedule from bringing the equipment on when you don’t want it to operate.

The screens will step through the Start T ime and then the S top T ime for each day of the week. You can quit at any point in the process by pressing the “Escape” key. There are two Start/Stop events available per day so the screen will show which event is being programmed. If you need only one event, leave Event #2 times to ZERO.

All times are in 24-hour military format, so 5:00 PM would be entered as 1700.

WMVAV Hldy ID 59 Holiday # 1 Stop Mon/Day.: xxxx [ July 4

The screens will step through the fourteen possible holidays, one period at a time. Line 2 shows which holiday is currently being programmed. Since a holiday period can encompass more than one day, you need to program the day the holiday starts and the day the holiday ends. If your holiday only lasts one day simply set both the Start Day and the Stop Day to the same value. Remember to combine the month and day into a single four-digit value.

HC Box Spts IDxxxx Damper/Airflow Spt Integral [Ki]..: xxx

The Box Controller normally opens it’s damper based on a Proportional Error from Setpoint. That means if the zone temperature is 4°F from setpoint, the damper would be 100% open or it would be modulating to provide the Maximum CFM on Pressure Independent boxes. If the error is less than 4°F , the damper may stagnate at that position and never satisfy the zone. If you add Integral into the damper calculation process, this will cause the damper or airflow calculations to continue to increase as long as the zone temperature is still above the setpoint. That means it can provide 100% or Maximum CFM before the 4°F error is achieved, bringing the zone under control faster than it normally would. Start with a small ( 5 or 10 ) value, if you use this, and monitor the effect it has. If you enter too large a value, you can create “hunting” situations that can cause the damper actuator to prematurely wear out.

Occupied Mode

If the VAVBOX controller is used on a non-fan-powered terminal unit that has reheat, the VAVBOX damper will move to the Nite/Reheat position whenever a Space Heating demand occurs and the HVAC unit is in Supply Air Cooling or Vent modes. When the HVAC unit is in Supply Air Heating mode the VAVBOX damper will modulate as required to maintain the Space Heating setpoint. This setting has no effect on fan powered terminal units when they are in the occupied mode.

Unoccupied Mode

When using non-fan powered terminal units, the VA VBOX damper will position itself in the Nite/Reheat minimum position. In order for fan powered terminal units to position the damper to the Nite/Reheat minimum position, the check for main fan status must be selected and the HVAC unit fan must be operating.

The Fan On Min is used for Parallel Fan boxes only . This is the damper position that will cause the Parallel Fan to start if the damper/airflow drops below this value. Normally the Parallel Fan only operates when the Reheat stages are activated. If this is not a Parallel Fan box, the last line will remain blank.

Damper Force Mode Screens

Damper Force ID 159 Enter Force Mode.: 0 0=Auto 1=Open 2=Clsd 3=Max 4=Min 5=Fixd

Set the appropriate Damper Force Mode by entering numbers 0 through

5. The Force Modes for each of these settings is outlined below.

0 = Auto This is the default setpoint. With this setting

the damper will operate normally and modulate according to the controller setpoints.

1= Open This setting will force the dampers to their fully

open position.

2= Clsd This setting will force the damper to it’s fully

closed position.

Press the “2” key to access the Damper Force Modes screen. Outputs Force is not available with the System Manager.

Modular Service Tool Instructions

1)Outputs Force

2)Dampers Force

Press the “2” key to access the Damper Force Modes screen. Outputs Force is available with the Modular Service Tool but is not used with the VAVBOX controller.

3= Max This setting will force the damper to the dampers

maximum airflow position set under Setpoint Screen #4

4= Min This setting will force the damper to the current

modes, minimum position setpoint. These modes are Vent Mode, Heat Mode and Cool Mode. They may each have a different minimum depending on how you configured the setpoints.

5=Fixd This setting will force the damper to a fixed

position based on the fixed position setpoint. See VAVBOX controller Setpoint Screen #7 for

available setpoint information.

Caution: The Damper Force Modes should only be used by quali-

fied service personnel. Serious damage to the ductwork could result if the dampers are all forced closed and the HVAC unit fan is operating.

Programming The MiniLink PD

Technical Guide

Configuration

In order to correctly setup the MiniLink PD you must first configure several parameters in regard to the type of system and operating parameters for the system it is installed on. Most of these values and operating parameters are only set once, at the initial system setup and are never changed.

System Manager Instructions

From any menu screen press the “Setpoint” key. The unit selection screen will appear requesting that you enter the unit ID number. All MiniLink PDs are set at address 60. Enter the correct unit loop number for the loop the MiniLink Polling Device is connected to (Loop 1 you would enter 1) and then enter 60. Press the “Enter” key. You will see the screen shown below.

1)Change Setpoint

2)Configure Unit

3)Damper Force ESC) Exit Menu

Press “2” on the keypad to enter the first unit configuration screen.

Modular Service Tool Instructions

From any menu screen press the “Configuration” key. The unit selection screen will appear requesting that you enter the unit ID number. Enter the correct unit ID number of the controller you want to configure and hit the “Enter” key. You will then see unit configuration screen #1.

Configuration Screen #1

Configuration Screen #2

Polling Unit Config Optimal Start Zone Target Unit: xx [Enter Target Zone]

This is the unit ID of the Zone that you want to be satisfied by the normally scheduled start time. If you enter “-1” into this box it will average all zones instead of picking a specific zone. If you do not require optimal start enter “0”.

Configuration Screen #3-62

Polling Unit Config Enable Alarm Polling Unit xx : YES [0=NO 1=YES]

Enabling Alarm Polling for the controller whose unit ID you have entered, allows any alarm from that controller to be polled and reported by the MiniLink Polling Device. If alarming is enabled when an alarm condition is encountered, the alarm light on the System Manager will be lit and the various alarms can be displayed for that controller at the System Manager by pressing the “Alarms” button. You must configure this setting to “YES” for each controller on the loop that you wish to receive alarms from.

Polling Unit Config Last Polled Zone Address: xx [Enter Last Zone]

Enter the address of the last controller (largest address number) for the local loop the MiniLink PD is connected to.
