AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate has a self-diagnostic function for the
electrical system (except input power). The face plate
monitors the electronic components and circuits for
correct operation. If a malfunction
occurs, anerrorcode appears in the
face plate display.
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face
plate buttons are inoperable except the SET button.
The SET button remains operational so the service
person can make the MANUAL ADVANCE DIAG-
NOSTICS to further isolate the defect.
