FAULT HANDLING, HISTORY & RUN HOURS
To protect the equipment, certain fault conditions trigger a lockout: The control shuts
down and will not restart until the fault is repaired. The lockout condition depends on a
combination of the failsafe level programmed, as well as the type of fault detected. All
of these options have a CLEAR icon. Pressing this icon clears the visible fault history,
compressor run hours, and fan run hours. Pressing and holding the CLEAR icon for
10 seconds will bring back the lifetime fault history and run hours.
