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 module is powered through the
ComfortLink Main Base Board (MBB). The Navigator
module has a modular telephone style (RJ14) connector
and should be connected to a specific terminal block in
the control box as found in Table 1. This device is intended for use on the LEN (Local Equipment Network) communications bus only. Do NOT connect the Navigator
module to the CCN (Carrier Comfort Network®) connector, as it may damage the device.
3. See Fig. 2-8 for Navigator LEN connection locations in
the units.
4. See Fig. 9 for Communication board details.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

OPERATION
To use the Navigator™ module, plug the RJ14 connector
into the LEN port. On power up, the Navigator module
displays:

Carrier
The Navigator module 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 and
the MBB-J5 plug if necessary. After successful upload of
information, the Navigator module begins its default display.
An example of the display in the default mode is:
EWT 54.2 °F
ENTERING FLUID TEMP
The entire local display command structure can be accessed
with the Navigator module. Pressing any key while in the default display mode will cause the Navigator module to enter its
manual mode. In this mode, all sub-modes and items of the
local display command structure, denoted on the display
screen, can be accessed. The Navigator module automatically
returns to the default display mode after 60 seconds of no
keypad activity. Pressing the and keys

simultaneously while the unit displays “Select a menu item”
will also return the device to its default display mode.
Navigating through Menu Structures — The ar-
row keys are used to scroll through the tiered command menu
structure. See the base unit Controls, Start-Up, Operation, and
Service Guide for menu structure. The key is used to
select a menu item or to accept data entry. The key
is used to exit to the next highest command level (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.
At any time, press the key repeatedly as needed
ESCAPE
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 one
of the 11 desired modes. Press to display the submodes within a top level mode.
Use the arrow keys to move the pointer (‘>’) to the desired
sub-mode. Up to four sub-modes will be displayed on the
Navigator module at one time. Continue pressing the arrow
keys as needed to find the desired sub-mode.

Password Protection — If an area is entered that is
password protected or an item is selected for change that is
password protected, the Navigator™ module will display:
Enter Password
The first digit of the password will be flashing. Hold either
of the arrow keys down to change the value of the first digit (if
necessary) and press to accept. Repeat the process for
the remaining three digits.
Password for 30RB units is 0111.
Password for all other units is 1111.
The message “Invalid Password” is displayed if the password is not correct. The password can be disabled from the
Navigator module, and can be changed.

Forcing Values and Configuring Items — Cer-
tain items are allowed to be forced and other items are
user-configurable. Both of these changes can be made using
the Navigator module. See the unit’s Control, Start-Up, Service
and Troubleshooting Guide for a list of forcible and configurable values.
To force an item, position the pointer at the item. Press the

finished. The Navigator module will display a lowercase ‘f’ to
the right of the value if it has been forced. If no ‘f’ is displayed,
the item was configurable. To clear a force, press so
that the value is again flashing. Simultaneously press the up
and down arrow keys. The value will stop flashing, the ‘f’ will
be removed, and the parameter will revert to its corresponding
input channel value.
