General Programming Information

Operator Interfaces Comparison

In order to configure and program the WattMaster VAV System controllers you must have a central operators interface or a personal computer with the Prism computer front end software installed. Two different central operators interfaces are available for programming of the WattMaster VAV Controls System. You may use either the Modular Service Tool and/or the Modular System Manager to access the status and setpoints of any controller on your communications loop.

The Modular Service Tool or the System Manager allow the user to view any temperature or output condition and change any setpoint to fine tune the operations of the total system. All keypad operations are simple and straightforward, utilizing non-cryptic plain English messages.

Display Screens & Data Entry Keys

The System Manager display screens and the Modular Service Tool display screens are very similar. For most setpoints and modes the only difference between using the Service Tool and the System Manager is a few differences in the function of the keypads. In this manual where a difference in the keypad input or the screens displayed exists between the two operators interfaces, both screens or keypads will be shown. See the chart below for a list of the keypad descriptions and functions.

2.) The “Search For Units” function must be performed on the System Manager upon initial system setup before this function will be available. See the “System Manager NM & MM Loop Search” section of this manual for complete instructions on performing a loop search.

Service Tool And System Manager

Entering Unit ID (Address)

With both the Modular Service Tool and the Modular System Manager You must enter the ID (Address) of the controller you wish to program

Unit Selection

Enter Unit ID#

Selected ID#: xxxx

With the main menu screen displayed, press the function key associated with the operation (setpoints, configuration, etc.) you want to perform. 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

You 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 Tool 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.

The screen above will appear a few seconds later. The last line of the display will have the letters SA (Stand Alone Mode), MM (Multiple System Manager Mode) or NM (Network Mode) followed by the current outdoor air temperature. The System Manager normally ships from the factory set for NM (Network Mode). If you have only one System Manager, the system must be set for NM (Network Mode). If you have multiple System Managers on your system, the system must be set for MM (Multiple System Managers Mode). If you believe your system is incorrectly configured, please follow the instructions that follow. If your system is configured correctly, proceed to the System Manager Network Mode Loop

Configuring For Stand-Alone Mode, Multiple System Managers Mode or Network Mode

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 WattMaster 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.

Press the “2” key on the keypad to enter the communications screen.

63) Network System

Enter Mode Of Op:.xx

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.

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.

Anytime you enter a unit ID with the Modular System Manager you will be asked for a passcode. Passcodes are not required to view Status Screens. The screen below will appear if this action requires passcode clearance.

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.

These two levels of passcodes are programmable by any Level 2 user. The default Level 1 passcode is “1111” and the default Level 2 passcode is “2222.”

Press the “1” .The following screen will be displayed.

Enter New Passcode Level 1.....: xxxx Level 2.....: xxxx [Must Be 4 Digits]

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.
