volatile memory upon demand.
Operation: Any time the control is powered, the fault code history can be retieved for display by depressing and releasing the
SW1 button once (less than 5 seconds); the LED will flash the Fault Code History (up to 5 fault codes from newest to oldest.)
Fault Code Clear
Function: When the SW1 button is pressed and held for an extended period (more than 5 seconds, less than 10 seconds),
the control erases the stored fault code history.
Operation: Any time the control is powered, the fault code history can be cleared by depressing and holding the SW1 button
for at least 5 seconds (but not more than 10 seconds) until the LED is blinking GREEN, and then release the switch while
the LED is still blinking GREEN. The fault code history will be erased.
