What Do the Different Modes Mean? (Cool, Dry, Heat, Auto, Fan)

Modified on Wed, 2 Apr at 1:32 PM

Overview

Not sure which mode to use on your Senville mini split? Here’s a simple breakdown of what each mode does and when to use it.

Mode Descriptions

Cool Mode

This is the standard air conditioning mode. It removes heat from the room to cool it down to your set temperature.

Best for: Hot summer days
How it works: Compressor and fan run to lower the room temperature
Tip: Set the temperature 2–3°F below room temp for best results

Dry Mode (Dehumidify)

Dry mode reduces humidity in the room without drastically changing the temperature.

Best for: Humid, sticky days
How it works: Runs at a low fan speed to extract moisture from the air
Tip: Great for preventing mold and musty odors

Heat Mode

Heat mode activates the mini split’s heat pump to warm the room.

Best for: Cold weather and winter use
How it works: Reverses the refrigeration cycle to bring warm air inside
Note: It may take a few minutes to start — this is normal

Auto Mode

Auto mode automatically switches between heating and cooling to maintain a stable temperature.

Best for: Mild or unpredictable weather
How it works: The system decides whether to heat or cool based on the current room temperature and your setpoint
Tip: Set a comfortable target temperature and let the system do the work

Fan Mode

Fan mode circulates air without heating or cooling it.

Best for: Air circulation when heating or cooling isn’t needed
How it works: Only the indoor fan runs; no compressor activity
Tip: Use it to ventilate a room or save energy

How to Change Modes

Use your Senville remote to press the “Mode” button. Each press cycles through the available modes: Cool → Dry → Heat → Auto → Fan.

Note: Available modes may vary slightly depending on your mini split model and whether it's a single- or multi-zone system.

Still Unsure?

If you’re unsure which mode is right for your space or your remote looks different, feel free to submit a support ticket or check your model’s user manual.
