Heat and cool from 2 to 8 zones, in any climate, with this new MXZ H2i® Hyper-Heating INVERTER™ mini split heat pump system. It's ideal for conditioning residential spaces such as bedrooms, living rooms, dining rooms, sunrooms, garages, basements, kitchens, bonus rooms and more. The ultra-efficient and extremely quiet outdoor unit uses an INVERTER-driven compressor and electronic LEV to control power usage, while the slim and beautiful wall-mounted indoor unit uses the i-see Sensor™ 3D and triple filtration to maximize your personal comfort.

H2i® Technology
Outdoor units provide Hyper-Heating performance down to -13° F outdoor ambient temperature and 100% heating capacity at 5° F outdoor ambient temperature.

i-see Sensor™ 3D Technology
Indoor units are equipped with the i-see Sensor™ 3D, which scans the room and adjusts airflow based on human heat signatures.

Powerful Mode
Need comfort fast? Turn on Powerful Mode to increase the fan speed at a lower/higher temperature setting until the room reaches optimal comfort.

Triple Action Filtration
Indoor units use a sophisticated multiple filtration system to ensure clean, healthy air throughout the rooms/zones they condition. The Hybrid Catechin washable pre-filter captures dust and eliminates odors, while the Blue Enzyme washable filter uses an enzyme catalyst to capture and eliminate allergens, germs, bacteria, and viruses. These units also contain a washable Platinum Catalyst Deodorizing Filter for high-powered odor absorption lasting up to two years.

Quiet Operation
Indoor units operate at very low sound levels (as low as 20 decibels). According to a study performed by the National Institute for Occupational Safety and Health, these units are quieter than a human whisper (30 decibels) at low speed.

Control Options
This system is compatible with the optional MHK1 wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (sold separately). If you prefer a standard, fully wired and functioning wall mount control, this system also works with the PAR-32MAA-J (sold separately and requires control adaptor MAC-333IF).

what is the BTU of each head?
ivy h on May 1, 2017
BEST ANSWER: The BTU's allocated to each head unit (air handler) is listed in parentheses in the product description.

For example ( 9,9,9,18)- This is a 4 zone system, 3 head units are 9k BTU's and 1 head unit is 18k BTU's.
