GENERAL
Check Package Contents —
Check the accessory
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, carrying
bag, and the Navigator display module.
The Navigator module is a portable display that conforms to
NEMA (National Electrical Manufacturers Association) 4
specifications for outdoor use in temperatures ranging from
–22 F (–30 C) to 158 F (70 C). The Navigator module can be
used to configure and perform service diagnostics on machines
equipped with Carrier ComfortLink controls.
The Navigator module keypad (see Fig. 1) contains eleven
menu LEDs and one Alarm Status LED, all of which are
red. The Navigator module is capable of displaying four
24-character lines of information on a back-lit liquid crystal
display. The Navigator module has four functional keys: the up
arrow ( ), down arrow ( ), , and
keys.
NOTE: The Navigator module should be removed after use.
There is not sufficient space to store the module in the unit
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 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 intend-
ed for use on the LEN (Local Equipment Network) com-
munications bus only. Do NOT connect the Navigator
module to the CCN (Carrier Comfort Network®) con-
nector, 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.
