Hi CEILING SET STANDARD
(Mild mode)
Use one of the two methods to set the fan tap.
When a wired remote controller is connected, none J31 provided
on the indoor unit PCB.
Note (1) “None” means that jumper wire is not provided on the PCB or the connection is cut.
Select the “STANDARD (Mild mode)” setting for “
C ” in #01 of “I/U FUNCTION
▲”
(indoor unit function) by using remote controller function setting.
