The axial fan speed controller is a special-purpose inverter designed for a variety of fan types. The frequency conversion speed control device is used to change the fan's rotation speed according to the set temperature, so that changing the fan's air volume to meet the needs of the manufacturing techniques, with the most economical operation energy consumption, and the highest comprehensive benefit is easy. This makes the frequency conversion speed regulation the most efficient and optimal speed regulation technique, thus achieving stepless speed regulation and creating a closed loop control system in order to achieve a constant pressure or constant flow control.
|On/Off||Switch on/off the fan|
|Manual Operation||Manually adjust the level of wind speed by 1-6|
|Automatic Operation||Automatically adjust the wind speed according to the set temperature and actual temperature. If the set temperature is greater than the actual temperature, increase the wind speed by 1 gear every 0.5 degrees. (for example: set 25 degrees, actual temperature 25 degrees and below, then increase 1 file of wind speed)|
|Settings||Setting temperature is at the range of 10-49 degrees, and the factory default is 25 degrees, and the set value can be automatically remembered.|
|+/-||To increase/decrease the temperature when setting|
|Up/Down||To increase/decrease the wind speed when manual operation|
