You can start a Fujitsu General wall-hung split air conditioner without the remote controller by using the manual operation button on the indoor unit. Here’s how:

Locate the Manual Button

  1. Open the front panel of the indoor unit (gently lift it upward until it locks in place).

  2. Look for a small push button on the right-hand side of the control board — it’s usually labeled “OPERATION,” “AUTO,” or “MANUAL/AUTO.”




Starting the Unit

  1. Press the manual operation button once → this will start the system in AUTO mode (cooling or heating depending on room temperature).

  2. The indicator light will illuminate, confirming operation.

  3. To stop the unit, press the same button again.

Important Notes

  • In manual mode, the system defaults to automatic fan speed and temperature control.

  • You cannot adjust temperature, mode, or fan speed without the remote.

  • The outdoor unit will only engage if conditions meet the automatic mode requirements (e.g., heating if the room is cold, cooling if it’s warm).

  • For troubleshooting or diagnostics, the remote is required — so consider borrowing or replacing one soon.
