Otherwise electrical functions like auto vane will not operate normally.
  • Page 59 8-1-2. Special Function Operation and Settings for M-NET Remote Controller • It is necessary to perform “group settings” and “paired settings” at making group settings of different refrigerant systems (multiple outdoor unit). (A) Group settings: Enter the indoor unit controlled by the remote controller, check the content of entries, and clear entries, etc.
  • Page 60 (2) Address check: Refer to section (1) regarding address entry. a) In making group settings: • Turn off the remote controller: Press the remote controller's ON/OFF button to stop operation (the indicator light will go off). • Locate the indoor unit address display mode: Press the FILTER and k buttons on the remote controller simultaneously and hold for two seconds.
