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.)
