Display Operational Mode (AC or HP) (5 sec)
Display Current/Stored Fault Code(s) if present
Note: If a fault condition is active, the control will
continue to display the active fault. It will not display
stored faults until the active fault is cleared.
Clear soft lockout
Clear hard lockout
Set Tonnage Configuration (5 sec), ONLY if the
Tonnage Configuration Error fault is currently active.
Set Operational Mode (AC or HP) (5 sec), ONLY if
the AC/HP Mode fault is currently active.
Note: If either of the previous 2 actions were taken, the
following will not occur on the same PUSH BUTTON
press.
Clear Fault Code Array, if faults are present
Clear soft lockout
Clear hard lockout
Resume normal LED display
Display will toggle between Operational Mode (AC/HP)
(5 sec) and Tonnage Configuration (5 sec)
