Axial Fan Speed Controller

Description
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.

Operating instructions

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

Alarm and protection functions
Overcurrent protection: Check if the motor is shorted or stuck.
Overheat protection: Check if the fan is stuck or the air intake is blocked.
