SAFETY CONSIDERATIONS

Installation of this accessory can be hazardous due to sys-

tem pressures, electrical components, and equipment location

(such as a roof or elevated structure).

Only trained, qualified installers and service technicians

should install, start up, and service this equipment.

When installing this accessory, observe precautions in the

literature, labels attached to the equipment, and any other

safety precautions that apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.

• Use care in handling and installing this accessory.

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 

Comfort

Link 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

Comfort

Link 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.
