How can I use cooling or heating on a multi-type system air conditioner?

cause Cause

■ 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

■ Check if an indoor unit connected to an outdoor unit is running.

Make sure both units are in the same mode.

■ If you cannot be sure of a mode of an indoor unit, turn off all indoor units and

select a mode for the unit you wish to use.
