Helpful Operating Tips:
- Relaxing Room Temperature At Night: Use sleep mode to gradually relax room temperature for energy saving.
- Curtains & Shades: Block sunlight in summer, allow solar heat in winter to help with cooling/heating costs.
- Close Doors: Confine cooling/heating to living areas by closing doors.
- Clear Around Outdoor Unit: Keep area around outdoor unit clear of debris. Hose off unit if needed.
- Rearrange The Room: Remove obstacles blocking airflow. Use swing louvers to direct airflow.
- Try 75 Degrees: 75°F is optimal for performance. Small temperature changes impact energy use.
- Lighting: Turn off unnecessary lights to reduce heat load.
- When Away From Home: Use auto mode and close windows/shades for energy saving.
- Use Of The Fan: Use fan on lower setting for energy efficiency.
