Deluxe Controls
Troubleshooting units which contain the deluxe control
option may be made easy by using the three LEDs
(light emitting diodes). These LEDs are provided for
indicating the operating mode of the controller. The
LEDs are intended to aid in troubleshooting. The LEDs
are labeled on the circuit board with numbers as
referenced in the table below.
