control
1) Four indoor units from A to E determine the respective instruction revolutions from the difference
between the remote controller setting temperature (Ts) and the indoor temperature (Ta), and
transmit this to the outdoor unit.
2) The outdoor unit receives the instructions from the indoor units, and the inverter operates the
compressor at the calculated revolutions.
3) The compressor operation range in each operating mode is shown in the left table.
