10. Demand Control
10. Upper Current Limitation Mode
NOTE
Since the pattern "A" and "B" perform the outdoor unit current demand control (compressor's suppressive
drive), it is easy to grasp energy saving amount.
However, it may cause the reduction of capacity in all indoor units of the same refrigerant system.
In order to make the indoor unit (group) only valid as the energy saving function where the Energy Saving
button is pressed and not to influence to other indoor units, be sure to set the outdoor unit EEPROM setting
DN18 to "1" and DN19 to "0".
(3) Serial-parallel I/O
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.
