CONTROLS SETUP

Controlling the Indoor Unit
The method and configuration of controlling the indoor unit will vary according to system requirements.
• It is possible to control up to 16 indoor units with one wired remote controller (Group Control). Master indoor unit determines how Slave
units operate.
• Set only one indoor unit to Master, set the others to Slave. After setting Group Control, turn off the power, and then turn it back on after one
(1) minute. To verify indoor units have been set to Group Control, Master indoor unit will beep once, each Slave indoor unit will beep five (5)
times.
• This indoor unit can be connected in a control group with any other types of LG indoor units.
It is possible to use a wireless remote controller at the same time as the wall controller.
• It is possible to connect a Dry Contact and Central controller at the same time (Master indoor unit only). Some Wired Remote Controllers,
however, can't operate when both Dry Contact and Central controller are connected.
• A Central controller can control all indoor units in a group by controlling the master unit of the group. (Set the address of the master indoor
unit first.)
• Slave indoor units cannot be individually controlled by the Central controller. The Wired Remote Controller will display indoor unit(s)
error(s).
