Description
This MRCOOL Olympus 4th Gen 3-zone system pairs a 48,000 BTU multi-zone heat pump condenser with three ceiling-concealed ducted indoor air handlers (18K + 12K + 12K BTU), delivering inverter-driven heating and cooling across three separate rooms from a single outdoor unit rated up to SEER2 24 and able to operate in outdoor temperatures as low as 5°F.
Highlights
- 3-zone, 48,000 BTU condenser — one outdoor heat pump powers three independent ceiling-concealed ducted indoor units (18K + 12K + 12K BTU), for room-by-room comfort control.
- High-efficiency inverter operation — SEER2 ratings up to 24 and HSPF2-4 up to 10.6 help manage energy costs while maintaining reliable heating and cooling.
- Cold-climate capable — the condenser is rated to operate in outdoor temperatures as low as 5°F.
- Flexible smart controls — manage the system with the MRCOOL SmartHVAC app, the included remote(s), or hands-free voice commands via Amazon Alexa and Google Assistant.
- Built-in safeguards — sleep mode, auto restart, and refrigerant leak detection help keep the system running safely and efficiently.
- Environmentally friendly refrigerant — uses low-GWP R-454B refrigerant across the condenser and all indoor units.
