(ii) Rotation of compressor start/stop order
) The compressors will be changed over by determinating the start/stop order in each heat load zone.
) In case of single use, the starting order of CM and CM will be changed over on each occasion when the out-
door unit stops.
) In case of combination use, the starting order of CM0(CM) 〔 CM 〕 and CM0(CM) 〔 CM 〕 will be
changed over on each occation when the master unit or slave unit stops all independently.
) In case of combination use, the starting order of master and slave units will be changed over on each occasion
when the master unit or slave unit stops all independently.
