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 T ool 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.

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

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.

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

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.

General Programming Information
System Manager Override Search
When a space sensor with override option is used with any VAVBOX
controller or WMVAV controller, the System Manager can determine
and report any controllers which are currently operating in an override
condition. 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
To access the Space Sensor Overrides screen, press the “Override” button located on the System Manager . A screen will appear asking you to
enter a unit ID. Enter an ID for any active controller on the system and
press "Enter". The following screen will appear.
Overrides Screen
SEARCHING!
After the System Manager completes its search, it will list the first unit
on the system that is currently in the override mode. Press the previous
or next button to scroll through all units that are in the Override Mode.

Screens. The screen below will appear if this action requires passcode
clearance.
System Manager Passcodes
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

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.”

Configuring The Modular Service Tool For
Network Or Stand-Alone Operation
As with the System Manager described previously, you must determine
if the mode displayed is correct for your system. Normally for most
applications the words “Network Mode” should be displayed in the
window. If it has been configured for Stand Alone mode you will see
the words “Stand Alone Mode” on the bottom line of the display. S tand
Alone Mode is only used when servicing or troubleshooting and is normally not used for general setup and programming as it only allows the
user to access the controller it is attached to and not the entire networked system
If your display indicates a different mode than the one you need, press
the "Enter" key and the following screen will appear.
1) Set Time & Date
2) Communications
3) Energy Saving
ESC) Exit Menu
Press the “2” key on the keypad to enter the communications screen.
Modular Service Tool Alarm Search
First, press the “Alarm” key. The Unit Selection screen below will be
displayed. Enter the Unit ID of any controller on the system and press
“Enter”. This is the unit ID of the loop where the alarm search will be
done. Unlike the System Manager, only the alarms on this loop will be
searched, not the entire system.
Unit Selection
Enter Unit ID#
Selected ID#: xxxx
The following screen will appear. The System Manager will search for
any active alarms on the local loop.

SEARCHING!
After the Modular Service T ool completes it’ s search, it will list the first
unit on the local loop, whose ID was entered, that currently has an active alarm. Press “Enter” to scroll through all the alarms for controllers
on that particular loop. To move to the next controller or back to the
previous unit use the “Prev” or “Next” arrows to move between controllers with alarms on the loop.

T o clear any alarms that are found you must fix the problem indicated in
the alarm. Once the problem is fixed, the alarm will clear from the screen
the next time the unit is polled.
Modular Service Tool Override Search
When a space sensor with override option is used with any VAVBOX
controller or WMVAV controller, the Modular Service Tool can determine and report any controllers which are currently operating in an override condition on the local loop whose ID (Address) has been entered
before running the search.
T o access the Space Sensor Overrides screen, press the “Override” button located on the Modular Service Tool . A screen will appear asking
you to enter a unit ID. Enter an ID for any active controller on the
particular local loop you wish to search and press "Enter". Unlike the
System Manager, only the overrides on this loop will be searched, not
the entire system. The following screen will appear .
