In step "8 Compressor preheating confirmation", the current preheat time is directly displayed, as
shown in the red box in the figure below. If the system currently detects that all the basic modules have
been continuously powered on for 2 hours or more, or the previous time when the modules were
powered on for 2 hours or more is less than 2 hours from the current time, preheat is completed and the
system can proceed to the next process. Otherwise, the system prompts UO (insufficient compressor
preheat time).
