Overview
This high wall indoor unit is flexible to fit any application with the 37MPRAQ single-zone system. Talk about controllability, the 45MPHAQ 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. 100% Heating capacity at 0° F (-17° C).
