2.2 STAT Switch
The momentary push-button labeled "STAT" on the front panel has two functions. When
held down MORE than 3 seconds, the microcontroller will reset. If held down LESS than
2 seconds, the LED matrix will display any faults being reported to the microcontroller.
Repeated presses of the STAT button will display subsequent alarms. The table below lists
all of the valid error codes.
