AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate has a selfĆdiagnostic function for the
electrical system (except input power). The face plate
monitors the electronic components and circuits for
correct operation. If a malfunction
occurs, an error code 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 DIAGNOSĆ
TICS to further isolate the defect.
CODE
POSSIBLE DEFECT

PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect 3.
PlugĆin transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
FACE PLATE REPLACEMENT: Be sure the valve is in service position (observe valve cycle indicator...see
below) when replacingthe face plate.
If, after installing and programming the replacement face place, the valve is not
in service position, do the followĆ
