This MR SLIM INVERTER-driven three-zone heat pump system, with ductless floor-standing indoor units, is the perfect solution for rooms with limited wall space. The indoor units can conveniently be installed on the lower wall, directly on or just above the floor.
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).
The M-Series INVERTER-driven compressor and linear expansion valve (LEV) works with the system’s sophisticated electronic controls to detect temperature changes in a room or zone, automatically changing speeds to adjust for precise capacity and temperature control.
These 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.
Mr. Slim Indoor Units operate at very low sounds levels (19-35 decibels). According to a study performed by the National Institute for Occupational Safety and Health, most Mr. Slim Indoor Units are quieter than a human whisper (30 decibels) at low speed.
Mitsubishi was clearly taking the environment into consideration when designing the M-Series line by using R410A refrigerant with zero Ozone Depletion Potential (ODP), 83% recyclable components, and washable filters made from natural materials on all models.
