OPERATION

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

ComfortLink

Navigator

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 de- fault 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 ENTER and ESCAPE 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 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 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 ESCAPE key repeatedly as needed 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 ENTER to display the sub- modes 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.
