Modular System Manager

As previously described, when you are connecting the Modular System Manager to a Networked System, the Modular System Manager is connected to the communications and power loop of the system via modular cables. These cables simply plug into the System Manager board and to any device with modular connectors on any local loop on the system. Devices with modular connectors include the Power/Comm Distribution Board, VAV/Zone controller and the Modular Polling device. By using these plug in connections wiring errors are virtually eliminated and system installation is fast and easy. See Figure 4 for typical connection information. See Figure 5 for typical Power/Comm board wiring and connection information.

When the System Manager is to be connected to a Stand Alone system, a 12 ft. cable with modular connectors on one end and stripped wire ends on the other end is provided for this purpose. This is used to facilitate connecting communications and power wiring to the Modular System Manager from a 24 VAC power source and to the HVAC unit controller communication wiring terminals. See Figure 6 for wiring details. If the supplied cable wire is not long enough for your installation, a standard modular cable of the correct length can be purchased through WattMaster and one of the modular connectors can be cutoff to allow for the transformer and communication terminal wiring connections. It is recommended that you do not splice the communications wire if at all possible. The transformer should be rated at 6 VA minimum power output.

WARNING!

DO NOT GROUND THE 24V TRANSFORMER THAT IS TO BE USED WITH THE POWER/COMM BOARDS. GROUNDING OF THE TRANSFORMER WILL DAMAGE THE POWER/COMM BOARD AND ALL BOARDS CONNECTED TO IT.A SEPARATE TRANSFORMER MUST BE USED FOR EACH POWER/COMMBOARD. NO EXCEPTIONS. DO NOT CONNECT ANY OTHER DEVICES TO THE TRANSFORMER USED FOR THE POWER/COMM BOARD!

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. The System Manager will try to detect the type of installation you have by scanning the communications loop. See the screens below. If it is configured for Stand-Alone operation, only the HVAC unit controller that the System Manger is connected to is available for programming. On a Networked System, all controllers on the communications loop are available for programming by entering their loop address (ID). If an Interconnected System is connected to the System Manager all controllers that are connected to the communication loop are available for programming.

If you are using the internal scheduling capability of the V AV/CA V 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.

If both the Start and Stop T imes are ZERO, the schedule is in a continuous OFF mode. (Use for Remote Signal Contact)

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.

EXAMPLE: 704 = July 4th (Note : Leading zero not required) 1225 = December 25

The MUA II D controller does not require whether you start configuring your heating or cooling stages first nor does it require that you utilize consecutive relays until all heating or cooling stages have been defined. 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 that there will only be one relay configured for Hot Gas Reheat and one relay for External Heat Enable, although it doesn’t prevent multiple relays from being selected.
