This system delivers efficient year-round performance — cooling in summer, heating in winter, and dehumidifying when needed. Monitor and control the temperature using the digital display or through the MRCOOL Smart Controller mobile app. Each indoor unit can also display troubleshooting alerts. You can control the system with the included remotes, the MRCOOL app, or even voice assistants like Amazon Alexa or Google Home.
Airflow direction is adjustable for maximum comfort, and each unit features a manual operation mode for quick system tests. In auto mode, the unit automatically adjusts output to maintain your preferred temperature. You can also enable a drying function for effective dehumidification.
Sleep Mode helps conserve energy overnight by adjusting operation within an 8-hour window.
The MRCOOL DIY Multi-Zone 48,000 BTU 22 SEER2 2 Zone Ductless Heat Pump Split System – 12K + 12K offers multiple customization options to enhance efficiency and comfort. Use the timer function to limit energy usage. If refrigerant levels drop, the system will alert you via the air handler display. Mute the units to disable light and sound notifications — perfect for bedrooms or workspaces. In the event of a power outage, the system resumes its previous settings automatically.
Maintenance is easy with built-in alerts. Troubleshooting codes appear on the front display, and cleaning reminders for the air filters ensure continued performance. Simply wipe down the indoor units with a dry or damp cloth to keep them in top shape.

| LONG DESCRIPTION |
We’re excited to introduce our new 5th Generation MRCOOL® DIY® 48k BTU Multi-Zone Ductless Mini-Split Condenser, because it’s better than its predecessor in nearly every way. You won’t need the services of an HVAC professional when you’re setting this unit up, because you can do it yourself, which saves lots of time and money! This condenser enables you to heat and cool up to 6 separate spaces equalling up to 2,000 sq. ft., meaning you’d be able to cover an entire home in the completely efficient comfort of a single DIY® system. You can install this system on your own because our innovative, patented pre-charged Quick Connect® line sets allow you to skip the lengthy and complicated process of evacuating and charging the system. These line sets are filled with R-454B refrigerant, a much more ecological and proficient upgrade from the previous refrigerant used in the last generation. This switch helps the system achieve impressive efficiency levels, like 21.8 SEER2 and an HSPF2-4 of 10. These line sets are sold separately. Once you install your system, you’ll be able to explore the variety of ways you can customize your comfort. For ultimate control, you can integrate system operations with the SmartHVAC app, available for Apple and Android phones, allowing you the ability to set schedules, manage modes of operation, monitor your systems all with the touch of a button. The app even enables you to set up integration with Amazon Alexa and Google Home, meaning you won’t have to move a finger to make your home more comfortable than ever. We pride ourselves on having one of the best warranties in the industry on this unit! Once you install your condenser, you’re entitled to a 5 year parts warranty, a 7 year compressor warranty, and, if you subscribe to the MRCOOL® Care Program, a Limited Lifetime Replacement warranty. The MRCOOL® DIY® is the right choice if you want fast, efficient comfort that won’t let you down!
