There are 2 types of control; demand control and infinity limit in the upper current limitation mode.
Either of them is controlled by the lower current limitation.
Serial-parallel I/O must be connected in order to perform demand control.
The below input is received by serial-parallel I/O, and demand control is performed.
The demand values can be set as needed with serial-parallel I/O.
* The rated current indicates the current value that is listed in the catalog or similar material.
* XX and YY are able to set in EEPROM of main outdoor unit.
