Working Timer - Unloading Delay
To reduce wear & tear of the compressor
components, an unloading delay time is set in the
controls that shuts-down the compressor after the
unloading delay time has counted down.
If the compressor is running in slow periods of the
day, the compressor could run for long periods in
the unloading stage, causing unnecessary
component wear and elevated energy costs.
With an unload delay time of 10 minutes, for
example, the compressor would run for 10
minutes in the unloading stage and then it would
shut down and enter a stand-by mode. Then when
the low pressure setting is reached, the
compressor automatically starts again.

2. Press the two arrow keys at the same time

then press enter.
It’s recommended not set the
unload delay too low. If the
compressor starts more than 5 times per hour, it
could cause unnecessary wear to components.
