Buzzer sound (peep) not heard from indoor unit — Remote control or indoor unit setting failed

What does peep buzzer mean?

When setting up two air conditioners in the same room to use separate remote controls, after pressing the ACL switch on the remote control, the indoor unit should emit a 'peep' sound. If this sound is not heard, the setting was not received by the indoor unit.

• Remote control not pointed correctly at the indoor unit.
• Signal not sent properly after pressing the ACL switch.
• Interference blocking the signal.
