Notes:please connect the outdoor unit to the power,
then connect the indoor unit to the power
otherwise,the failure code[95]may appear
At this time press the "self-check''button on the wired controller for at least 10 senconds to delete the failure code.(The machine's operation will not be influenced by such a phenomenon)
