Wi-Fi Enabled (Built-In or Optional Controller)

Enables remote operation and monitoring of the system through a smart device when connected to a Wi-Fi network.

°C / °F Temperature Display Change

Allows switching between Celsius and Fahrenheit temperature display formats.

Horizontal Swing

Automatically moves the louvers left and right to evenly distribute air across the space.

Turbo Mode

Temporarily boosts system output to rapidly cool or heat the space.

Fan Mode

Circulates indoor air without heating or cooling for ventilation and air movement.

Self-Diagnosis

Monitors system operation and displays error codes to assist with troubleshooting and service.

Dry (Dehumidification) Mode

Reduces indoor humidity by removing excess moisture from the air while maintaining comfort.

Cold Mode

This symbol signifies that the air conditioner will cool the room by removing heat from the indoor air.

Sleep Mode

Automatically increases cooling or decreases heating by 1°C per hour for 2 hours, then holds steady for 5 hours before switching off, ensuring comfort and energy savings while you sleep.

Auto Restart

Automatically restores the unit to its previous operating mode and settings after a power interruption.

What is Lorem Ipsum 21?

Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Louver Position Memory

Automatically returns the airflow louvers to their last position when the unit is powered back on.

Low Ambient Heating/Cooling

The unit can operate in cooling mode during the winter down to 5º F to cool an inner room.

What is Lorem Ipsum 24?

Heating mode works by reversing the refrigeration cycle, extracting heat from the outside air and transferring it indoors. To activate it, you'll typically look for a sun symbol on your remote or unit and set your desired temperature.

Seasonal Energy Efficiency Ratio

SEER stands for Seasonal Energy Efficiency Ratio, and it measures the annual energy consumption and efficiency of the unit’s cooling ability in typical day-to-day use. The higher the SEER value, the less energy the unit will use.

he Department of Energy (DOE) is changing the way HVAC systems are tested. New M1 testing procedures are thorough, demanding a lower SEER2 equipment rating and thus paving the way for a more sustainable future.

Heating Seasonal Performance Factor

HSPF quantifies the total heating output (measured in British Thermal Units or BTUs) produced by a heat pump during a typical heating season, divided by the total electricity consumed (measured in watt-hours). A newer, more accurate standard for measuring heat pump efficiency is HSPF2.

IAQ (Indoor air Quality)

Ensures the indoor unit improves air quality by removing contaminants, allergens, and odors, providing cleaner and healthier air inside the building.

What is Lorem Ipsum 28?

Lorem Ipsum is simply dummy text of the printing and typesetting industry.

ECO Mode

Reduces energy consumption by optimizing compressor and fan operation while maintaining comfort.

Included Accessories

Every KOIF-KIDF Hyper Heat system includes essential accessories
for fast setup, convenient control, and long-lasting performance.
