Welcome To My Shop Specifications: Manual automatic integration control: 1. Manual control without temperature probe. Click/double-click (double-click on the speed is not too fast) button up/down gear. Each shift will continue after 20 seconds and the gears will be stored automatically. The indicator light 2 will flash rapidly within 20 seconds (when temperature control is disabled). When the flash is stopped, it indicates that the file has been stored. The 3/1 indicator is always lit when you are unable to continue to increase/cannot continue to decrease position. 2. When installing the temperature probe, use the manual speed as the initial low speed (bottom line speed). When the temperature exceeds the acceleration temperature, the fan speed will accelerate smoothly as the temperature increases. When the temperature reaches and exceeds the sum of the acceleration temperature and the acceleration width (full speed temperature), the fan will run at full speed. Setting method: Attachment: The controller supports the control of the reverse timing fan. First, turn off the power and remove the fan. Press the Setup button to power up the controller. Always set the button (about 3 seconds) until the three lights turn into a dual flash state, then release the button.
