Start-up delay
When changing the operating type (Local/Remote/Network),
the control normally undergoes the transition stage during
which the unit is stopped, and then allowed to start again
(start-up delay is applied).
Unit stop function
This function controls the unit compressor capacity reduction.
If there is an alarm or a demand to stop, it forces the
compressors to the minimum capacity before stopping them.
