Did You Know?

1. Did you know that the first air conditioner was invented by Willis Carrier in 1902 to control the humidity in a printing plant, and not for the purpose of cooling the air?
2. Fujitsu air conditioners use a special “i-PAM” (intelligent Power Module) technology that allows for more efficient operation, reducing energy consumption and saving on electricity bills.
3. If you’re struggling to reset your Fujitsu air conditioner, you can try performing a “hard reset” by turning off the unit, unplugging it from the power source, and waiting for about 15 minutes before plugging it back in and turning it on again. This can sometimes resolve minor technical issues.
4. Fujitsu air conditioners feature a unique sensor technology called “Human Sensor”, which detects human movement in a room and adjusts the air conditioning accordingly. This helps to save energy by only cooling or heating spaces that are occupied.
5. To further enhance the efficiency of their air conditioners, Fujitsu has developed a special “Economy Operation” mode that allows the unit to operate at slightly higher temperatures, consuming less energy without compromising comfort. This is especially useful during milder weather conditions, when large cooling or heating capacities are not necessary.

Resetting A Fujitsu Air Conditioner

To reset your Fujitsu air conditioner, follow these steps:

  1. Unplug the air conditioner from the power outlet: Start by disconnecting the power supply to the unit. Locate the power cord at the back of the air conditioner and unplug it from the electrical socket. This will ensure that the unit is completely disconnected from the power source.

  2. Remove the front panel: To access the reset button, you need to remove the front panel of the air conditioner. Most Fujitsu air conditioners have a removable front panel. Refer to the user manual for specific instructions on how to remove the front panel of your particular model.

  3. Locate the reset button: Inside the control board area, you will find the reset button. It is usually a small, round button labeled “RESET.” Look for it and take note of its location.

  4. Press and hold the reset button: With the front panel removed, press and hold the reset button for approximately 5 seconds. This will reset the air conditioner’s internal settings and restore it to its original state.

  5. Replace the front panel: After releasing the reset button, carefully place the front panel back into its original position. Ensure that it is securely fastened and aligned properly with the rest of the unit.

  6. Plug the air conditioner back in: Finally, plug the power cord back into the electrical socket. Make sure it is firmly connected and that there are no loose connections.

Your Fujitsu air conditioner should now be reset and ready for use. If the issue persists, you may need to consult a professional technician for further assistance.
