23. GROUP CONTROL
1 Setting group for 1 remote control unit
- When using a remote control thermostat, the thermostat setting is used for all indoor units in the
group.
- During group control, up to a maximum of 16 indoor units can be connected. (Do not mix heat
pump units and cooling-only units.)
- Do not mix manual settings and automatic settings. (manual settings take priority.)
- The master unit and slave units can all be centrally controlled during group control. /
Automatic setting for group control
- If the power supplies for indoor units which are connected are turned on simultaneously, the
indoor unit numbers will be determined automatically after approximately 1 minute. (DIP switch
settings are not necessary.) /
NOTE:
- Correct wiring connections are basic requirements for automatic setting. If the wires are connected
incorrectly when the power is turned on, the settings will not be made correctly and operation will
not be possible.
