Figure O-GI-1. The human interface panel on the Trane Packaged Fresh Air unit
Standard IntelliPak Unit Control Fea-
tures
The human interface panel is easy to
read and requires less time for building
maintenance personnel to learn to
interact with the unit. It features a clear
language display (in English, Spanish, or
French) that shows all of the Packaged
Fresh Air unit control parameters,
including system on/off, demand limiting
type, night setback setpoints, and many
other setpoints. All adjustments are done
through the human interface keypad. See
Figure O-GI-1.
Also, the human interface panel allows
you to monitor diagnostic points such as
sensor failures, supply airflow loss, and
inoperative refrigerant circuit. No special
tools are required for servicing the unit.
Diagnostics are held in memory, even
during power loss. This allows the
operator/servicer to diagnose the failure
root cause. All setup parameters are
preset from the factory, requiring less
startup time.

Human Interface Panel (HI)
The human interface panel provides a 16-
button keypad for monitoring, setting,
editing and controlling. The HI panel is
mounted in the unit’s main control panel,
accessible through the unit’s control panel
door.
The optional remote-mount version of the
human interface (RHI) panel has all the
functions of the unit-mounted version,
except for the service mode. To use a
RHI, the unit must be equipped with the
remote HI interface option, which
includes an interprocessor communica-
tions bridge (IPCB). The RHI can be
located up to 1,000 feet (304.8 m) from
the unit. A single RHI can be used to
monitor and control up to four fresh air
units, that have each been supplied with a
RHI interface option (IPCB module).
The main menus of the human interface
panels are:
•
STATUS
monitors temperature,
pressure, humidity, setpoints, and input
and output status.
•
CUSTOM
key allows the user to
customize a status report - consisting of
up to four screens of the data available
in the main Status menu.
•
SETPOINT
allows the user to edit all
factory preset default setpoints.
•
DIAGNOSTICS
allows the user to
review active and historical lists of
diagnostic conditions. A total of 49
different diagnostics can be read at the
human interface (HI) panel and the last
20 diagnostics can be held in an active
history buffer log at the HI panel.
•
SETUP
allows the user to edit control
parameters, sensor selections, setpoint
source selections, output definitions,
and numerous other points in this
menu. All points have factory preset
values to keep unnecessary editing to a
minimum.
•
CONFIGURATION
allows changing of
factory-preset unit configuration
information. This information can be
edited only if certain options are field-
installed or deleted from the unit. For
example, if a communication interface
(LCI-I) module or ventilation override
module (VOM) were field-installed, the
unit configuration will require editing to
reflect those options for proper unit
operation.
•
SERVICE
allows servicing or
troubleshooting the unit by selecting
component control outputs such as
compressors, fans, damper position,
etc. This menu is accessible only at the
unit-mounted human interface panel.
