    Installation and Control

    Fans are designed for installation on walls or ceilings.

    Basic version fan can be manually operated via a separate ON/OFF switch or the light switch.

    TH version fan starts when the switch is turned ON or when the indoor humidity level exceeds the adjustable set point (60%–90%). After the switch is turned OFF, or once the humidity level drops below the set value, the fan continues to run for the duration set on the timer, adjustable from 2 to 30 minutes.

    TP version fan starts when the motion sensor is activated. After the motion sensor is turned OFF, the fan continues to run for the duration set on the timer, adjustable from 2 to 30 minutes.
