Outdoor Unit Installation ENGLISH Introduction - Overview Outdoor Unit Product Information The FlexFit Multi-zone Heat Pump systems feature DC inverter technology to deliver high energy efficiency. The inverter technology operates variable speed compressors and fan motors. The outdoor is equipped with electronic expansion valves , which control refrigerant flow independently to each indoor unit that is installed. All of the outdoor units feature an internal oil separator to increase compressor live.
Introduction - Overview Outdoor Unit Product Information ENGLISH Temperature Control and the Inverter The outdoor unit inverter will operate the compressor, outdoor fan motor and indoor fan motor at the proper speed to provide enough capacity to satisfy the heat load from all operating indoor units. As the temperature in the zones gets closer to the setpoint requirement, the inverter will slow everything down. This is normal operation.
