Fault: The air conditioner unit does not operate After We see This Type Of Errors.

Causes / Action:

<<<Acson Ac Error Codes And Troubleshooting Method>>>

– Power failure, or the fuse needs to be replaced.
– The power plug is disconnected.
– It is possible that your delay timer has been set incorrectly.
– If the fault persist after all these verifications, please contact the air conditioner unit installer.

Fault: The air flow is too low

Wireless Remote Controller

  • The compact LCD transmitter is able to operate the air conditioner unit within the distance of 9 metres.
  • Fan motor speed can be set at low / medium / high or automatic.
  • Sleep mode auto control will gradually increase or decrease the setting temperature to provide a
    comfortable surrounding for sleeping.
