How Smart Remote Usage Lowers Your Electricity Bill

Using your Daikin AC remote function properly can help you save a lot on electricity. Even small changes in AC remote settings can reduce the load on your AC unit and improve efficiency.

• Use Intelligent Eye: Turn on the INTELLIGENT EYE sensor so the AC reduces power when no one is in the room.
• Avoid overcooling: Do not set very low temperatures, as it increases power usage without much extra comfort.
• Clean air filters regularly: Dirty filters block airflow and make the AC work harder, which increases electricity consumption.
• Block sunlight: Use curtains or blinds to stop heat from entering, helping your AC cool faster and use less power.
• Keep fan on AUTO: AUTO mode adjusts fan speed as needed, which helps manage power use efficiently.

Note: For best results, keep the temperature between 24°C to 26°C for comfortable cooling and lower electricity bills. To learn more ways to save on your AC usage, check our guide on how to reduce AC bill.
