High Speed

If any value of PM2.5, CO2 or VOC exceeds the limit, the fan will work at high speed directly. When the detected PM2.5 value is below 50 - its backlash , the

detected CO2 value is below 800 - its backlash, and the detected VOC value is below 2 - its backlash, the fan will run at low speed.（PM2.5 default backlash is

10ug/m3, CO2 default backlash is 50ppm，VOC default backlash is 1）

● Manual Mode: Set the fan speed at high, medium, low manually.

● Mute Mode: the fan runs at low speed.

3. Timer off setting：Press to set the shutdown time. The timer icon is flashing, 00:00 displays on the screen, press again, the time will increase up to

press + and hold on 5 seconds to reset the filter alarm time. After setting, the filter alarm time is stored correspondingly in the secret menu.

7. Sensors parameters checking: Under normal working interface, press to check the parameters of CO2, PM2.5, Temperature, Humidity etc . If there is

error of the sensor, it will skip to display the next sensor parameter. Same logic to VOC.

8. Valve Control: Under normal working interface, press and hold on 5 seconds, the valve is on, the valve-on icon displays on the screen. Press and
