How can I use cooling or heating on a multi-type system air conditioner?
■ If cooling or heating cannot be turned on a wired or wireless remote
controller or beep sounds five times, it is due to different modes used for
indoor and outdoor units.
■ It can happen when a user tries to use a mode that is different from one
that is selected for an indoor unit.
How to fix
Make sure both units are in the same mode.
