5. Service Menu
The service menu ("F0" to "F9") may be used to change settings, acquire diagnostic
information, and to view alarm history.
To access the "F0" through "F9" service menu selections, you must first disconnect the
service jumper (excluding "F5" which is accessible with or without the service jumper in
place). The service jumper is located behind the wire cover below the control box and
connects the control board K151 connector terminals 7 and 8 (white) together. When the
service jumper is in place, only the "F5" selection is accessible. Be sure to reconnect the
service jumper when finished.
