- About the selection of indoor units
Š It is not possible to register an indoor unit with red letters as a main unit. In this case, the indoor unit is registered as a sub
unit automatically.
Š When indoor units with 3 and 4 available fan speeds are mixed in the same remote control group, register the indoor unit
with 4 fan speeds as the main unit.
Š When mixing indoor units with auto louvre function and indoor units without auto louvre function together in the same
H-LINK, register one unit with auto louvre function as the main unit. Otherwise, the auto louvre function becomes disabled
for the entire H-LINK. The same applies to other functions as well.
5 Tap "Register" to register the main unit while the group and indoor unit are selected.
• If the group and indoor unit for the main unit are not selected, the "Register" indication is greyed out and therefore cannot be
tapped.
• The colour of the buttons of the registered group and the indoor unit changes to blue, and the following information is displayed
inside the buttons.
