Precise and smooth refrigerant flow control is achieved by
using a DC Inverter control in conjunction with individual
indoor unit electronic expansion valve control. This allows
high precision comfortable temperature control of ±0.5°C.
Precision refrigerant flow control
A comfortable room condition is maintained during oil
recovery mode because the product continues to operate
without stopping the cooling or heating operation.
*: AIRSTAGE VR-II series is not available.
Non-stop oil recovery operation
Low noise mode
Two low noise modes can be selected automatically by
quiet priority setting and capacity priority setting depending
on the indoor environment and outside temperature load.
This feature can be controlled via outdoor unit external input
and/or system controller.
