In case of no fault and the system still does not meet the start-up conditions, the host digital display standby code is
as follows:
555.0 The indoor machine capacity is beyond the
outdoor machine capacity of 150% or less
than 50%, then the system indicates standby
555.1 26 degree standby
555.2 Low pressure (gas) standby
555.3 If above 54 degrees , the outdoor cooling
machine will not run
555.5 Power restriction
