Description
Overview
This LG Multi F heat pump system pairs the KUMXB301A outdoor unit with 2 LG convertible mid static ducted indoor units for dual-zone heating and cooling. Every indoor unit in this system is the same style, so each room gets matching appearance, airflow and controls. The system runs on 208/230V, 1-phase, 60 Hz power and uses R-32 refrigerant.
What Is Included
- 1 x KUMXB301A multi-zone outdoor unit (4 direct ports, LG R1 twin rotary inverter compressor)
- 1 x KNUJB121A (12,000 BTU LG convertible mid static ducted indoor unit)
- 1 x KNUJB181A (18,000 BTU LG convertible mid static ducted indoor unit)
Performance
This exact ducted combination (12K + 18K) is listed in the LG Combination Data Manual at 18 SEER2, 11.4 EER2 and 8.5 HSPF2, with a rated cooling capacity of 27,400 BTU/h and a rated heating capacity of 30,000 BTU/h. Heating operation is rated down to -4 F outdoor temperature (wet bulb) and cooling operation from 14 F to 118 F.
Comfort and Noise
Each zone has its own indoor unit and set point, so occupied rooms can be conditioned independently while unused rooms stay idle. The inverter compressor adjusts its speed to match the load, which holds temperatures steadily and reduces on/off cycling.
Smart Features
Wi-Fi control through the LG ThinQ app is available with the optional PWFMDD200 Wi-Fi module. Ducted indoor units require a wired controller, sold separately (for example PREMTB101 or PREMTA201).
Use Case Fit
Concealed ducted indoor units sit in an attic, crawlspace, closet or soffit and deliver air through ductwork, keeping equipment out of sight. Confirm room loads, line set lengths and electrical requirements before ordering. Professional installation is recommended.
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 60 Days of Purchase.
