The unit operates on R454B refrigerant and uses an inverter-driven compressor to modulate capacity precisely, maintaining set points without the energy loss of single-stage cycling. Built-in protections include compressor overcurrent detection, thermal protection, high pressure protection, and fan motor overheating and voltage protection. Licensed HVAC technicians install this unit as the outdoor component of a ductless or ducted split system serving residential or light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis outdoor unit is engineered for multi-zone configurations and is compatible with M-Series and P-Series indoor units as well as CITY MULTI indoor units. A branch box is required when connecting M-Series or P-Series indoor units. The unit is rated for coastal environments, with seacoast protection applied to the heat exchanger and base panel, tested for 2,000 hours in accordance with ASTM B117 salt spray standards. Its hyper heat capability supports reliable heating performance at low ambient outdoor temperatures, making it well suited for cold-climate installations in both residential and light commercial buildings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverter-driven compressor modulates output to match exact load, reducing energy waste\u003c\/li\u003e\n  \u003cli\u003e42,000 BTU\/h capacity supports multiple simultaneous indoor zones\u003c\/li\u003e\n  \u003cli\u003eR454B refrigerant compliant with low-GWP refrigerant requirements\u003c\/li\u003e\n  \u003cli\u003eSeacoast-rated heat exchanger and base panel, tested to ASTM B117 for 2,000 hours\u003c\/li\u003e\n  \u003cli\u003e1 degree F thermal differential for precise zone temperature control\u003c\/li\u003e\n  \u003cli\u003eQuiet outdoor operation comparable to normal conversational noise levels\u003c\/li\u003e\n  \u003cli\u003eMultiple integrated safety protections: overcurrent, thermal, high pressure, and fan motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with M-Series and P-Series indoor units and CITY MULTI indoor units.
