This MR SLIM INVERTER-driven three-zone heat pump system, with concealed horizontal ducted indoor units, is ideal for conditioning rooms with limited wall space, because the evaporator stays hidden in the ceiling, floor, or closet.
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.
