Group Setting Procedure
- The group setting consists of the master unit setting and the slave unit setting. The indoor unit, which is connected
directly to the remote control switch, is set as the master unit, and the indoor unit connected with the transmission
line is set as the slave unit.
- Without the remote control switch, the control by the remote control switch group is not available.
Therefore, in this case, one indoor unit is set as one group. (Only the master unit is set without the slave unit.)
- When setting the remote control switch group without transmission line between indoor units, the indoor unit
connected with the remote control switch shall be set as master unit.
- When using the remote control switch ( ) or receiver kit
central station automatically set the slave unit.
Check for the setting state by the slave unit setting mode.
