What is the difference between EC Fan and 3 Speed Fan

 

The difference between EC Fan and 3 Speed Fan:

 

EC Fan

EC fans are fans with an EC motor. An EC motor requires a control signal that specifies the requested fan speed. This control signal can be digital (Modbus RTU communication) or analog (typically 0-10 Volt). The control signal can be generated manually via a control switch (in steps) or via a potentiometer (stepless). It can also be generated by an HVAC sensor or an HVAC controller for demand-based fan speed control.

 

3 Speed Fan

A three-speed ceiling fan has a low, medium and high speed, usually with a pull chain to change it back and forth between the settings. This means that you have to get up every time you want to switch to another speed.
