Description
Overview
This Mitsubishi Electric Hyper-Heat multi-zone heat pump system pairs the MXZ-3D30NLHZ outdoor unit with 3 SEZ-AD low-static ducted indoor units for tri-zone heating and cooling. Every indoor unit in this system uses the same mount style, so each room gets matching appearance, airflow and controls. The system runs on 208/230V, 1-phase, 60 Hz power and uses R-454B refrigerant.
What Is Included
- 1 x MXZ-3D30NLHZ multi-zone outdoor unit (3-port, Inverter Twin Rotary compressor)
- 2 x SEZ-AD09NL (9,000 BTU class SEZ-AD low-static ducted)
- 1 x SEZ-AD18NL (18,000 BTU class SEZ-AD low-static ducted)
Performance
Ducted system ratings for the MXZ-3D30NLHZ: up to 16 SEER2, 10.3 EER2 and 8 HSPF2, with rated capacities of 27,400 BTU/h cooling and 27,600 BTU/h heating. Connected indoor capacity for this combination totals 36,000 BTU/h class (9K + 9K + 18K). Hyper-Heat technology maintains heating operation down to -13 F outdoor temperature. Final efficiency depends on the exact AHRI-matched combination.
Comfort and Noise
Each zone has its own indoor unit and controller, so occupied rooms can be conditioned independently while unused rooms stay idle. The INVERTER-driven compressor modulates capacity to hold set points closely and reduce on/off cycling. Outdoor sound level is rated at 56 dB(A).
Smart Features
Wi-Fi control through the Mitsubishi Electric Comfort app is available with the optional Wi-Fi interface kit. Each indoor unit supports Mitsubishi Electric wireless or wired controllers for local zone control.
Use Case Fit
Concealed ducted indoor units sit in an attic, crawlspace or soffit and deliver air through short duct runs, keeping equipment out of sight. Confirm room loads, line set lengths and electrical requirements before ordering.
Value and Reliability
Bundling the outdoor unit with matched indoor units in one product simplifies ordering. Warranty: 7 Years Compressor & 5 Years Parts | Registration Required within 90 Days of Purchase
