Modes and Fan Control

Last updated: June 16, 2026

Mysa gives you full control over your mini-split's operating modes and fan speeds — from the app or directly on the device.

Operating Modes

Mode

What It Does

Heat

Warms the room to your target temperature

Cool

Cools the room to your target temperature

Auto

Automatically switches between heat and cool

Dry

Removes humidity without significant cooling

Fan Only

Circulates air without heating or cooling

Note Available modes depend on your specific unit. Not all mini-splits support all modes.

Special Modes Not Supported

Some unit-specific modes cannot be controlled through Mysa:

  • Freeze protection (8°C / 46°F)

  • Eco/Energy-saving

  • Turbo/Powerful/Jet

  • I-Feel/Follow-Me

To use these features, use your original remote.

Changing Modes

In the app:

  1. Tap your thermostat

  2. Tap the mode icon (snowflake, flame, or current mode indicator)

  3. Select your desired mode

On the device:

  1. Press the M (Mode) button on the side of Mysa

  2. Each press cycles to the next available mode

  3. The display shows the current mode icon

Fan Speed Control

Most mini-splits offer multiple fan speeds:

  • Low

  • Medium

  • High

  • Auto (unit adjusts based on need)

The number of speeds depends on your unit — typically 3 to 5 options.

In the app:

  1. Tap your thermostat

  2. Tap the fan icon

  3. Select your preferred speed

On the device:

  1. Press the Fan button (fan icon) on the side of Mysa

  2. Each press cycles to the next speed

  3. The display shows the current fan setting

Swing Control

If your unit supports swing, you can control it through the app:

  • Vertical swing — Moves the louvers up and down to distribute air throughout the room

  • Horizontal swing — Moves the louvers side to side (if your unit supports controlling horizontal swing remotely — many don't)

Temperature Range

Mysa supports temperatures from 16°C to 31°C (61°F to 88°F). Low temperature modes found on some heat pumps are not supported.

Off mode: Turn your unit completely off while keeping Mysa monitoring room conditions. Note that your schedule can override off mode — use "Hold Indefinitely" for a true off that won't be overridden.

Mode Indicator

Mysa indicates the current mode using the colored LEDs on the side of the device. The LED color changes based on which mode is active.

Tips for Efficient Use

Avoid big setbacks — large temperature swings are inefficient for mini-split heat pumps. Try 2-4°C setbacks for short periods like overnight. For prolonged trips or vacations, you can turn it off or set it much lower.

Dry mode is ideal for humid days when you want dehumidification without heavy cooling.

Fan Only circulates air without using the compressor, saving energy while maintaining air movement.

Higher fan speeds cool or heat faster but use more energy and create more noise.
