（dual stages、1#、2#）cannot be set after startup.

If the startup conditions are not satisfied, press "Start" button and a prompt will display at the top of the
pop-up boot window. It will show that "compressor start conditions are not met, please check status

time of restart, and the startup temperature of compressor. The startup can be confirmed right now, but
unit will start until the compressor startup conditions are met. The main page will keep displaying
"compressor start conditions are not met, please check status information". Refer to the detailed
