The iQ Drive

Air Conditioning System features fully

variable speed compressor technology and variable speed

indoor and outdoor motors. The system provides variable

cooling capacity as needed. It operates near the nominal

rated capacity at the thermostat set point and modulates

as temperature difference between set point and room

temperature changes. The system may run at additional

18% capacity to provide rapid cooling. The system has a

built-in humidity control that will activate humidiﬁer equipment

(if supplied), and reduces blower speed if indoor relative

humidity is greater than set point (default set at 60%).
