(2) Compressor control (Master unit/slave unit)
(a) Starting compressor
(i) Compressor starting order
After turning the power on, firstly CM1 compressor starts. (In case of the combination use, it is CM01 of master unit)
And corresponding to the condition of under-dome temperature and to the required capacity of indoor units thermo-
stat ON, the next compressor will start sequentially, and finally maximum 6 compressors ( in case of 3 outdoor units
combination use) will start simultaneously.
