Owners Manual


Model: 40MPHA
At 42 SEER, there’s nothing more efficient* when paired with its outdoor single zone counterpart 38MPRA. The High Wall is flexible to fit any application from 38MPRA single zone to the 38MGR multi-zone system. Talk about controllability, the new 40MPHA indoor unit features either built-in Wi-Fi® that gives you control from virtually anywhere or compatibility with third party thermostats when the 24V Interface is installed. The High Wall also offers a Relative Humidity Sensor to customize the humidity level for more comfortable air and an occupancy sensor that senses a person in a room and can direct airflow either toward or away from that person.
