Della Vario Single Zone Mini Splits - Energy-Saving, Smart Control

The Vario Series focuses on two main things: energy efficiency and smart features. These units have high SEER2 ratings (up to 23), which means they use less electricity.

They also come with smart controls, like the DELLA app and a Geo Location feature, that automatically adjust the temperature for you.

These mini splits use inverter tech. This means the system can adjust its speed instead of constantly turning on and off.

It operates at the exact speed required to maintain a comfortable room temperature, resulting in significant energy savings. You can explore all our high-efficiency models to see how they compare.

Yes, it can. The Vario Series is a heat pump system, which means it provides both cooling in the summer and heating in the winter.

It is designed to work well in a wide range of climates, operating in temperatures from -4°F to 122°F. It functions as a powerful mini split heat pump, making it a great choice for year-round use.

Refrigerant is the substance that allows the unit to cool the air.

• R410A is a common, reliable refrigerant that has been used for many years.
• R454B is a newer option with a lower Global Warming Potential (GWP), making it a more environmentally friendly choice.

We offer models with both R454B refrigerant and the traditional R410A refrigerant.

Yes. All Vario Series units are Wi-Fi Ready. You can connect them to your home network and use the DELLA app on your phone to change the temperature, set schedules, and switch modes from anywhere. They also work with voice commands through Alexa or Google Assistant.

The “I Feel” mode uses a temperature sensor located inside the remote control. The mini split will then adjust its operation to reach the set temperature where the remote is, rather than where the indoor unit is mounted. This helps make the temperature right where you are in the room.

This collection features the single-zone models from our Vario Series. A single-zone system means one outdoor unit connects to one indoor unit to manage the temperature in a single room or open area. If you need to heat or cool one specific space, these single-zone mini splits are the right choice.

Our Vario Series mini splits feature a “WeatherReady” design. The outdoor unit's coils have a gold fin coating that helps prevent rust and corrosion from rain, salt, and other outdoor elements.

For cold weather, the Intelligent Defrost feature automatically melts frost buildup to keep the unit running smoothly.

These units are designed to be low-maintenance. The PureClean function helps stop dust and mold buildup inside the unit. You will also get a Filter-Cleaning Reminder to let you know when it’s time to wash the air filter. This helps keep the air clean and the unit running efficiently.
