OVERVIEW
A glossary has been provided to assist the reader in understanding distinctive terms and
phrases. These terms and phrases appear in italics.
LJ Wing’s Digital Control System, AireLogic, is designed to give the user the ultimate in
unit performance and operational flexibility, adaptability, and reliability in a user-friendly
package. The AireLogic DDC system is a standard component on LJ Wing heating and
cooling units. Because the AireLogic system encompasses a wide variety of unit
types, not all of the system’s capabilities and functions are relevant to all units.
Where a function is similar but different between recirculating and non-recirculating
units or direct fired or indirect fired units, the function is explained separately.
AireLogic accepts single or multiple units on the system network. Each unit can be
provided with a BACview. The BACview connects to the unit control module via the
Local Access Port (see Figure 1 for the location of the Local Access Port). The operating
parameters for individual units may be input through the BACview. A PC may also be
connected to the network. This allows the user to configure each unit separately, or all
units can be configured simultaneously. A controls contractor can provide assistance in
networking.
Figure 1
The BACview ships with a cable. One end of the cable consists of a pre-wired black
screw terminal connector while the other end consists of a 5-pin red-tipped plug.
For MRT and MRT-Expert systems, plug the pre-wired black screw terminal connector
into the back of the BACview and plug the 5-pin red-tipped plug into the bottom of the
room sensor. Because the room sensor is hard-wired to the controller via the Rnet port on
the left-hand side of the controller and the BACview is connected to the room sensor via
the plug connection on the bottom of the room sensor, this creates a communications link
between the BACview and the controller without having to directly wire the BACview to
the controller.

7
It is easy to move the BACview between the location of the room sensor in the space and
the unit’s location without having to do any additional wiring. Simply unplug the
BACview from the bottom of the room sensor in the space and take it to where the unit is
located. Then, plug the BACview into the Local Access Port on the controller as shown in
Figure 1. To go from where the unit is located to the room sensor in the space, unplug the
BACview from the Local Access Port and take it to the room sensor. Then, plug the
BACview into the bottom of the room sensor.
For MDT and MDT-Expert systems, simply plug the BACview into the Local Access Port
on the controller as shown in Figure 1 as a room sensor is not provided with these
systems.
If there are multiple units at the jobsite, the BACview can easily be unplugged from one
unit and plugged into another. For this reason, it is not recommended to hardwire the
BACview into the Rnet port on the left-hand side of the controller because it sacrifices the
convenience of portability.
LJ Wing’s AireLogic system also includes operational modes such as time scheduling,
filter monitoring, and multiple damper control and temperature control schemes. All of
these modes provide the maximum in unit operational flexibility.
The optional airflow station imparts unparalleled adaptability into the operation of each
unit. A daily self-calibration enables AireLogic to detect the exact ratio of outside and
return air entering the unit. Then AireLogic daily fine-tunes the unit’s operation based on
these new parameters. Air volume can vary because of changes in static pressure
conditions due to loading filters, VAV boxes, and building dynamics. These varying
conditions influence the ventilation air provided by the unit. On certain models of
recirculating direct-fired heaters this impacts the allowable equivalent temperature rise of
the unit that is allowed under the latest ANSI standard for direct-fired heaters.
AireLogic diagnostic capabilities insure swift response to abnormal unit conditions. An
alarm is generated anytime a discrepancy exists between operational parameters and
actual unit operation. An alarm indication is displayed at the BACview and system PC in
text format. In the Diagnostics section of this manual is a list of all alarms and possible
causes and solutions.
All of the features of the AireLogic system are designed to provide the user with real time
information. At any time the user can display all of the operational parameters, make
changes, if necessary, and observe the various temperature, pressure, and damper
readings. The system’s diagnostic capabilities provide the user with up to the minute
status reporting. (BACview remote keypad or WebCTRL internet connection is required
for these features.)

NETWORKING
AireLogic is adaptable to a variety of different network architectures and protocols. Each
controller has built-in protocol translation and can be configured for operation on
ARCnet156 or EIA-485 communication networks. See Appendix III for specific
controller specifications.
The AireLogic system can be connected to most existing building automation systems.
Some systems may require the use of special controllers and network communication
devices.

UNIT OPERATING MODES
There are three different modes that control the supply fan and unit operation:
Off
Manual
Auto
There are also four different methods for controlling the operating modes:
a remote control panel with one or two rotating adjustment knobs (MRT and
MDT controls)
an intelligent room sensor and BACview panel with LCD display (MRT-Expert
controls)
an BACview panel with LCD display (MDT-Expert controls)
any of the these controls with an internet-based WebCTRL interface or other 3rd
party building automation system
MRT Controls:
Modulating room temperature (MRT) control is the most basic AireLogic control for
room temperature. The MRT control system includes a remote control panel equipped
with 1 or 2 potentiometers, 3 or more pilot lights, and up to 2 switches.
AireLogic units configured for MRT or MRT-Expert controls will have a fixed
discharge temperature of 70°F if the room temperature sensor is disconnected or
otherwise fails to communicate with the unit control module.
UNIT OFF MODE
Off Mode is the default unit operational mode. To place the unit in Off Mode, rotate the
“temperature setpoint” knob on the remote control panel counterclockwise to the stop.
This will place the unit in the OFF mode and extinguish the “fan on” light. The OFF
mode prevents the unit from starting.

10
UNIT MANUAL MODE
Manual Mode allows the unit to turn on. To place the unit in Manual Mode, rotate the
“temperature setpoint” knob on the remote control panel clockwise to the desired room
temperature setpoint. This will place the unit in the MANUAL mode and enable the fan
and burner. See Heating/Ventilating/Cooling Modes and Energy Saving Modes of this
manual for more information.
UNIT AUTO MODE
The MRT control does not support the time clock, night setback, or auxiliary unit
enable functions.
MDT Controls:
Modulating discharge temperature (MDT) control is the most basic AireLogic control for
discharge temperature. The MDT control system includes a remote control panel
equipped with 1 or 2 potentiometers, 3 or more pilot lights, and up to 2 switches.
UNIT OFF MODE
Off Mode is the default unit operational mode. To place the unit in the Off Mode, rotate
the “temperature setpoint” knob on the remote control panel counterclockwise to the
stop. This will place the unit in the OFF mode and extinguish the “fan on” light. The OFF
mode prevents the unit from starting.
UNIT MANUAL MODE
Manual Mode allows the unit to turn on. To place the unit in the Manual Mode, rotate the
“temperature setpoint” knob on the remote control panel clockwise to the desired
discharge air temperature setpoint. This will place the unit in the MANUAL mode and
enable the fan and burner. See Heating/Ventilating/Cooling Modes and Energy Saving
Modes of this manual for more information.
UNIT AUTO MODE
The MDT control does not support the time clock, night setback, or auxiliary unit
enable functions.
MRT-Expert Controls:
The AireLogic MRT-Expert (modulating room temperature) control system provides full
information regarding unit operation and allows the user to adjust all operational
parameters using the BACview panel. See the Menu Selection Tree for BACview section
of this manual for more information about navigating the BACview menus.
AireLogic units configured for MRT or MRT-Expert controls will have a fixed
discharge temperature of 70°F if the room temperature sensor is disconnected or
otherwise fails to communicate with the unit control module.
UNIT OFF MODE
Off Mode is the default unit operational mode. To place the unit in Off Mode, scroll
through the Unit Modes menu tree, locate the AUTO/OFF/MANUAL branch, and select
OFF. This will place the unit in the OFF mode. The OFF mode prevents the fan and
burner from starting. This mode will override the Time Clock and Night Setback
functions.
