6) Suppose the centralized control address (SA2-Addr-CC) of the master unit for one GMV system
is set to “1 1 1 1 X”, this system is the master mode system and its running mode will take the
priority. That is, the running mode of the indoor units of other systems cannot conflict with that of
this master mode system. For instance, when the running mode of the master mode system is set
to cooling, it for the indoor units of other systems cannot be set to heating.
1.3.1.3 Compressor Emergency Operation DIP Switch (SA3_COMP-E)
Corresponding to 2#-6# compressors, the compressor emergency operation DIP switch
(SA3_COMP-E) is used for aftersales emergency settings when an exception occurs on a compressor. It
can shield the operation of the abnormal compressor in a short time and guarantee the emergency
operation of other compressors.
When it is required to shield the operation of 2#-6# compressors upon failure, set the DIP switch
according to the following methods:
