UNLOADED TIME: _____**************

The LOAD/UNLOAD CYCLES is a total count of the number of times this compressor has cycled while running in Power$ync IIMode. This can be useful to determine if the blowdown solenoid valve needs to be serviced or replaced. The CYCLES/MINUTE displays the number of cycles that have occurred in the last minute. This number is updated every minute as long as the compressor is running. LOADED TIME and UNLOADED TIME display, in seconds, how long the compressor was loaded and unloaded in the last cycle. Tests have shown that short cycles can cause overheating of the compressor. To ensure that short cycling will not cause overheating of the
