Fault Code Reset

The last 4 fault codes can be erased from memory by power-
ing up the control with “G” energized and then applying “R”
to the  “W1” terminal 3 times within 6 seconds. The control
will acknowledge the reset by turning on the red LED for
2 seconds.

FAULT CODE RECOVERY

On power up, last 4 faults, if any, will be flashed on the red
LED.  The newest fault detected will flash first and the oldest
last. There will be a 2 second delay between fault code
flashes. Solid red LED error codes will not be displayed.

The Green LED  will be on solid during last fault recovery.
At any other time the control is powered, the Green LED
indicator light will operate as shown in Table 14 and the red
LED will flash LitePort data (one flash) every 20 seconds.
