This MR SLIM INVERTER-driven four-zone heat pump system, with ceiling-recessed indoor units, is ideal for conditioning bedrooms, home offices, living rooms, and dining rooms with limited wall space. These systems offer a wide airflow pattern for maximum air distribution with an unimposing presence, and can be conveniently installed in a hard ceiling with an access panel or a 2’ x 2’ drop ceiling.
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).
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.
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.
