The OE392-12 Modular System Manager SD provides a direct link to enable you to view the status and adjust the setpoints of the VCM-X, VCM-X E-BUS, VCB-X, RNE, SA E-BUS, VCM, VAV/CAV, MUA II or VAV/Zone Controller on the control system communications loop. The System Manager SD is housed in a beige-colored plastic enclosure. The System Manager has a programmable 4 Gigabyte SD card and is equipped with a 4-line-by-20-character backlighted display panel and a 24-key membrane keypad for data selection and entry. All keypad operations are simple and straight forward, utilizing non-cryptic plain English language messages. Menu-driven programming allows for easy setup and operation without the need for specialized training. The System Manager also has 2 integral LEDs for user notiﬁ cation of system alarm conditions and override initiations. Protection from unauthorized users is provided by the System Manager’s integral multi-level passcode authorization programming.

On a Networked System, the Modular System Manager is connected to the communications and power loop of the system via modular cables that simply plug into the System Manager board and the Power/Comm Distribution Board. This virtually eliminates wiring errors and makes installation fast and easy. When it is to be connected to a Stand-Alone system, a cable with modular connectors on one end and stripped wire ends on the other end is provided to facilitate connecting communications and power to the Modular System Manager from the 24 VAC power source and the HVAC unit controller communication wiring terminals.

The Modular System Manager is designed for wall mounting. Mounting holes are provided to attach the Modular System Manager to a standard handy box. It is recommended that the System Manager be mounted at approximately eye level to allow for ease of programming and reading of the display. The System Manager is typically mounted in the building manager’s or superintendent’s ofﬁ ce or in an equipment room. The attractive enclosure is quite suitable for mounting in any location.

When the System Manager is to be connected to a Stand Alone system,

a 12-foot cable with modular connectors on one end and stripped wire

ends on the other end is provided for this purpose. This is used to fa-

cilitate 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 on page 9

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

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, keep Event #2’s times set at ZERO.

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

If both the Start and Stop Times are ZERO, the schedule is in a continuous OFF mode. (Also, use for Remote Forced Occupied applications

using the Forced Occupied Binary Input.)

If both the Start and Stop Times are 2359, the schedule is in a continuous ON mode.

NOTE: The second line displays which day of the week is cur-

rently being programmed. The day of the week automatically increments as you exit the Event #2 screen for the day and continue to the next day’s Event #1 screen.

CAUTION: The controller ships with all schedules set to

zero so that the controller will not attempt to heat or cool before you have conﬁ gured the system.

Operator Interfaces

In order to conﬁ gure and program the Orion System controllers, you must have an Operator’s Interface or a personal computer with the Prism 2 computer front-end software installed. Three different Operator Interfaces are available for programming of the Orion Controls System—the Modular Service Tool SD, the Modular System Manager SD, and/or the System Manager TS II. These devices allow you to access the status and setpoints of the controllers on your communications loop. This manual describes the Modular System Manager SD. If using the Modular Service Tool SD, please see the Modular Service Tool SD Quick Start Guide. If using the System Manager TS II, please see the System Manager TS II Technical Guide. If using Prism 2, please see the Prism 2 Technical Guide.

The Modular System Manager SD allows you to view any input or output status and change any setpoint to ﬁ ne-tune the operations of the total system. All keypad operations are simple and straightforward, utilizing non-cryptic plain English messages.

When each VCB-X Controller is conﬁ gured for the ﬁ rst time, it is best to start with screen #1 and proceed to each Setpoint Screen in numerical order until you have viewed all available Setpoint Screens. This ensures that you have seen all of the available VCB-X Controller Setpoint possibilities and have the opportunity to change or accept the defaults for each screen. Once the unit Setpoints are conﬁ gured and you decide to change one of the screen options, it is helpful to know what screen number contains the conﬁ guration you wish to change.

CAV/MUA Dual Mode (Hood On/Off)—In CAV (Hood Off) operation, the unit will use the Occupied HVAC Setpoints from Setpoint Screen #1 in reference to a Space or Return Air Temperature Sensor. When exhaust hoods are turned on and the Hood On contact closes, the unit switches from CAV Space Temperature Control to MUA Outdoor Air Temperature control operation (Hood On). At this point the Outdoor Damper modulates to full open, and these Hood On setpoints become the Outdoor Air Temperature Mode Enable Setpoints.

When the exhaust hoods are turned off and the Hood On contact opens, the unit reverts back to Space or Return Air Temperature Control and uses the Occupied HVAC Setpoints from the previous screen.

Space Temperature Control of High Percentage Outside Air Units—

This option allows for Space Temperature control of 100% Outside Air MUA Units or units with a high percentage of Outdoor Air (normally 50% or greater). For this application you would conﬁ gure “Space Tem- perature w/High OA %” for the Controlling Sensor option. The intent of this sequence is to allow Space Temperature control of the unit while preventing the dumping of hot or cold outside air into the space during the Space Vent Mode of operation.

Once the Space Temperature is satisﬁ ed, before switching to Vent Mode, the controller compares the Outside Air Temperature to these Hood On HVAC setpoints to determine if a continued demand for heating or cooling is required to prevent dumping. If there is no demand, the VCB-X Controller switches to Vent Mode. If the Outside Air Temperature is greater than the Hood On HVAC Cooling Setpoint or less than the Hood On HVAC Heating Setpoint, plus the Occupied Deadband, the VCB-X Controller will continue mechanical cooling or heating operation and stage it as necessary to maintain the Vent Mode Supply Air Setpoint (Calculated to be halfway between the Mode Enable Setpoints). A call for Heating or Cooling from the Space Sensor will cancel this tempering operation.

Supply Air Tempering—In the VAV Supply Air Tempering application (see the VCB-X Controller Technical Guide for full details), the unit will enter the Cooling and Heating Modes based on the outdoor temperature. The outdoor Heating and Cooling Setpoints are conﬁ gured using the Hood On OAT Cooling and Heating Setpoints on this screen. In this application, the economizer can operate in any mode, if necessary, to achieve the supply air setpoint. Night Setback Heating and Morning Warm Up are both controlled to the Warm Up Supply Air Setpoint.

NOTE: For this Supply Air Tempering application, the Heating Supply

Air Setpoint on Setpoint Screen #21 should be set at least 2°F below the Cooling Supply Air Setpoint.

On MUA conﬁ gured units (100% or high percentage Outdoor Air units), or if this is a unit in Hood On MUA operation, Dehumidiﬁ cation will be initiated if the Outdoor Air Dewpoint rises 2°F above this setpoint. If the humidity falls 2°F below this setpoint, the unit will leave the Dehumidiﬁ cation Mode.

This screen can be used to set the Space Humidity Setpoint and to set the Space Humidity Reset range used to reset the Suction Coil Temperature Setpoint.

On units where Indoor Humidity is used to initiate Dehumidiﬁ cation (non MUA units), the Low Reset Source (Lo Rst Src) is the Dehumidiﬁ cation Setpoint, and as the Indoor Humidity rises above this setpoint, Dehumidiﬁ cation will be initiated. If the humidity falls 1% below this setpoint, the unit will leave the Dehumidiﬁ cation Mode.

If no reset of the Coil Temperature Setpoint is desired, set the High Reset Source (Hi Rst Src) at the same value as the Low Reset Source. If reset of the Coil Temperature Setpoint is desired, when the Indoor Humidity rises above the Low Reset Source, Dehumidiﬁ cation will be initiated and the Coil Temperature Setpoint will be set at the Coil Temperature High Reset Limit (conﬁ gured in the next screen).

The High Reset Source (Hi Rst Src) is the Indoor Humidity level at which the Coil Temperature will be reset to the Coil Temperature Low Reset Limit (conﬁ gured in the next screen). As the Indoor Humidity rises between the Low Reset Source and the High Reset Source, the Coil Temperature Setpoint will be proportionally reset between the Coil Temperature High Reset Limit down to the Coil Temperature Low Reset Limit.

On MUA units where the Outdoor Dewpoint Setpoint is used to initiate Dehumidiﬁ cation, this screen is only used to set the Indoor Humid- ity values that will reset the Coil Temperature Setpoint. As described above, as the Indoor Humidity rises within the range created by the Low and High Reset Source Setpoints, the Coil Temperature Setpoint will be proportionally reset between the High and Low Coil Temperature Reset Limits.

Building Pressure

Setpt....: 0.02”

Deadband....: 0.01”

The VCB-X can maintain Building Static Pressure anytime the Supply Fan is operating. A Building Pressure Transducer must be connected to the VCB-X EM1 Expansion Module. The following are the available control options.

Direct Acting Building Pressure Control

• On/Off Exhaust Fan—If an On/Off Exhaust Fan is

being used, a relay output must be conﬁ gured for “Exhaust Fan”. This relay will energize whenever the Building Pressure rises above the Building Pressure Setpoint by the Deadband amount. The relay will de energize when the Building Pressure falls below the Building Pressure Setpoint by the Deadband amount.

• Exhaust Fan VFD or Modulating Exhaust

Damper—If conﬁ gured for Modulating Exhaust, a user-

adjustable voltage output (AOUT1 – Building Pressure Output on the VCB-X EM1 Expansion Module) will be used to control this fan or damper. An Exhaust Relay can be conﬁ gured if necessary to enable the fan or damper. Whenever the Building Pressure rises above the Building Pressure Setpoint by the Deadband amount, the Exhaust Fan Relay will energize and the Modulat ing Signal will activate to control to the Building Pressure Setpoint. If the Building Pressure falls below the Building Pressure Setpoint by the Deadband amount, the Modulating Signal will modulate towards 0% as it attempts to maintain the Building Pressure Setpoint. The Exhaust Fan Relay remains energized as long as the Modulating Signal is above 0%.

• Supply Fan VFD – Contact WattMaster regarding this

Reverse Acting Building Pressure Control option. It should not be used in most applications. If this option is selected, the user-adjustable Supply Fan VFD Output (AOUT1 on the VCB-X) will be used to control the Supply Fan VFD to maintain the Building Pressure Setpoint in similar fashion to the Outdoor Air Damper control described above.

• Outdoor Air Damper—If this option is conﬁ gured,

the VCB-X will use the user-adjustable Economizer/ Outdoor Air Damper output signal (AOUT2 – Economizer Control Signal) to maintain the Building Pressure Setpoint. Whenever the Building Pressure falls below the Building Pressure Setpoint by the Deadband amount, the modulating Economizer Output Signal will modulate the damper open to control to the Building Pressure Setpoint. If the Building Pressure rises above the Building Pressure Setpoint by the Deadband amount, the damper will modulate towards closed as it attempts to maintain the Building Pressure Setpoint. When this option is selected, no Economizer free cooling or CO

Hot Water Valve

Protection POS: 0%

If the Supply Fan is on and the Supply Air Temperature (SAT) falls below the Low SAT Cutoff Setpoint for 1 minute, the Hot Water Valve will move to this position. If the SAT rises 5°F above the Low SAT Cutoff, the valve will return to normal operation. If the SAT remains below the Low SAT Cutoff Setpoint for 10 minutes, the unit will shut down and a Low SAT Cutoff Alarm will be generated.

For cold climates where freezing temperatures may be experienced, a Pre-Heater relay output can be activated to control a preheat coil based on the Outdoor Air Temperature to prevent freezing of Water Coils. One of the VCB-X Relay Outputs must be conﬁ gured for the Pre-Heater control. When conﬁ gured, any time the Outdoor Air Temperature falls below the Preheat Setpoint during Occupied Mode and the HVAC unit’s fan is running, the Pre-Heater relay will activate. This setpoint will also be used to enable the Preheater if the PREHEAT-X Controller is being used in conjunction with the VCB-X Controller. IF the PREHEAT-X Controller is being used with the VCB-X Controller, a relay on the VCBX cannot also be conﬁ gured as Preheat and energize for Preheat function.

The VAV/Zone Controller normally opens its 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 airﬂ ow 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

During Supply Air Cooling Mode, if the space being served by this damper is satisﬁ ed and has no cooling demand, the damper will close to this Cool Min setting. This provides a minimum amount of airﬂ ow into the space for ventilation, even if the space does not require additional cooling. During Supply Air Heating Mode, if the space being served by this damper is satisﬁ ed and has no heating demand, the damper will close to this Heat Min setting. This provides a minimum amount of airﬂ ow into the space for ventilation, even if the space does not require additional heating.

The Night Min position is the position the damper will move to when the system is in Pushbutton Override Mode and this particular damper is not part of that Override Group. When not in Pushbutton Override, pressure independent boxes will only go to the Night Min CFM setpoint position if it is set to 0. Pressure dependent boxes will always stay at the Night Min position. This Night Min position only affects non fan powered boxes. The Fan On Min is the minimum damper or airﬂ ow setting used to activate the parallel fan if installed. Pressure Independent = CFM.

The VAV/Zone Controller can be setup to generate an alarm anytime the box goes into the Occupied Mode and the Zone Temperature exceeds the user-deﬁ ned alarm limits for a user-deﬁ ned period of time. A High Temperature Alarm Setpoint is created by adding the Hi Zone Alarm offset to the current Cooling Setpoint. The Low Temperature Alarm Setpoint is created by adding the Lo Zone Alarm offset to the cur- rent Heating Setpoint. If the zone temperature exceeds either of these limits for a period deﬁ ned by the Alarm Delay setpoint, the controller can generate an alarm callout if all the optional hardware components required for this to occur are installed.
