GENERAL
Check Package Contents — Check
package for
missing parts or shipping damage. If damage is found, or any
part is missing, file a claim with the shipper immediately. The
package contains these instructions, clamp and screw, and the
Navigator display module.
The Navigator is a portable display module that conforms to
NEMA 4 specifications for outdoor use in temperatures ranging from –22 F (–30 C) to 158 F (70 C). The Navigator can be
used to configure and perform service diagnostics on machines
equipped with Carrier ComfortLink controls.
The Navigator keypad (see Fig. 1) contains eleven menu
LED's and one Alarm Status LED, all of which are red. The
Navigator is capable of displaying four 24-character lines of
information on a back-lit liquid crystal display. The Navigator
has four functional keys which are the up arrow (
), down
arrow (
), ENTER and ESCAPE keys.
NOTE: The Navigator should be removed after use. There is
not sufficient space to store the module in the chiller control
panel. The module will NOT fit between the inner panel and
outer cover.

INSTALLATION
1. The Navigator display module is intended to be a mobile
device, so there are no holes in the device for permanent
mounting. The module has a magnetic mount that is
strong enough to hold the device in place on any clean,
dry metal surface.
2. The Navigator is powered through the ComfortLink Main
Base Board (MBB). The Navigator has a modular telephone style (RJ14) connector and should be connected to
terminal block TB3 in the control box. This device is intended for use on the LEN (Local Equipment Network)
communications bus only. Do NOT connect the Navigator to the CCN (Carrier Comfort Network) connector.
You may damage the device. Terminal block TB3 locations are listed in Table 1 on page 2.
3. Figures 2-6 show TB3 locations in the units. Note that the
LEN connector is clearly marked and is on the left side of
the terminal block. If the Navigator is intended to remain
with the chiller, secure the cable near TB3 to prevent accidental damage to the RJ14 connector or the TB3 LEN
connector. A clamp and screw are provided in the package for this purpose. An 1/8-in. hole should be drilled to
use the clamp and screw.
4. Figure 7 shows Communication board details and
dimensions.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

modes, denoted on the display screen, can be accessed. The
Navigator automatically returns to the default display mode
after 60 minutes of no keypad activity. Pressing the ENTER
and ESCAPE keys simultaneously while the unit displays
“Select a menu item” will also log the device out and return it
to its default display mode.
OPERATION
To use the Navigator, plug the RJ14 connector into the LEN
port at TB3. On power up, the Navigator displays:
ComfortLink
Navigator
By
Carrier
Navigating through Menu Structures — The arrow keys are used to scroll up and down to select sub-modes
within a mode or items within a sub-mode. See the base unit
troubleshooting guide for menu structure. The ENTER key is
used to select a menu item or to accept data entry. The
ESCAPE key is used to exit to the next highest mode or to
cancel data entry. The sub-mode and item displays will wrap
around with the last and first items separated by a line of dashes
on the display. The ‘>’ symbol is the pointer and is located at
the left side of the display.
Press the ESCAPE key to display “Select a menu item” on
the screen. This is the top level and the arrow keys are used to
move the red LED to the one of the 11 desired modes. Press
ENTER to display the sub-modes within a top level mode.
The Navigator will upload the appropriate display tables
from the Main Base Board (MBB) that it is connected to. A
‘Communication failure’ message will be displayed if any
errors are encountered. Check the wiring at the connector or the
MBB-J5 plug if necessary. After successful upload of information, the Navigator begins its default display. All items in the
Run Status menu are displayed one at a time in this mode. An
example of the display in the default mode is:
EWT
54.2 °F
ENTERING FLUID TEMP
The different levels of modes can be accessed with the
Navigator. See the base unit controls and troubleshooting guide
for more information.
Pressing any key while in the default display mode will
cause the Navigator to enter its manual mode. In this mode, all
sub-modes and items within the eleven top level configuration

The Navigator will remain in the expanded display mode
until the ESCAPE key is pressed. Use the arrow keys to view
expansions for any of the other sub-modes within the Configuration mode.
Once a sub-mode is selected, the first four items in that submode will be displayed. For example, in the Temperatures
mode, under the sub-mode UNIT, the Navigator will display:

stop flashing, the ‘f’ will be removed and the value will read
the corresponding input channel for its value.
To edit a user-configurable item, operate the chiller in
Service Test mode, enter run hours and compressor starts or reset current alarms or history, use the ENTER key to make the
value flash. Next, use the arrow keys to adjust the item so that
the desired value is displayed and press ENTER .
Adjusting the Contrast — The contrast of the display
can be adjusted to suit ambient conditions. To adjust the contrast of the Navigator, press the ESCAPE key until the display reads, “Select a menu item.” Using the arrow keys move

The connection cable (P/N 912-990010-1) can be replaced
if damaged. Replacement cables are available from Replacement Components Division. Remove the Navigator from the
LEN connection before proceeding.
1. Remove the 6 screws from the back of the case to gain
access to the internal plug for the device, and keep
them for installation later.
2. The back cover is connected to the touch pad by a ribbon
cable. The ribbon cable is not long enough to allow the
two halves to be completely separated. To be able to access the plug connection, slightly offset the back cover.
Be careful not to damage the ribbon cable.
3. Unplug the damaged cable.
4. Plug in the new cable.
5. Insert the rubber grommet (included with new cable assembly) into the cable entrance hole.
6. Realign the two halves of the Navigator. Be sure that the
grommet is properly seated in the cable entrance hole.
7. Reinstall the 6 screws previously removed.
NOTE: Failure to properly seal the Navigator with the screws
and grommet will compromise the watertight integrity of the
device.
ADJUSTING BRIGHTNESS — Pressing ENTER will
cause the “OFF” to flash. Use the up or down arrow keys to
change “OFF” to “ON”. Pressing ENTER will illuminate all
LEDs and display all pixels in the view screen. Pressing
TAB
and
simultaneously allows the user to adjust the display
brightness. The display will read:
Adjust Brightness

Use the up or down arrow keys to adjust the brightness.
The screen’s brightness will change with the adjustment. Press
ENTER to accept the change. The Navigator will keep this
setting as long as it is plugged in to the LEN bus.
