I have a EC fan which came with a simple speed control unit which plugs into the mains voltage fan itself ( I believe the control side only works on 0-10v). The speed control consists simply of a 10Kohm potentiometer on a 5mt long lead which plugs into the fan body (tiny three pin plug/socket).
As a matter of interest, the fan runs full speed if the controller (pot) is unplugged.
I would love to be able to replace the simple pot with a unit which would control the fan speed based on temperature (using remote sensor). More precisely, I would like to be able to set a minimum fan speed with one control pot, and have thus the fan speed auto ramp according to the set temperature (second control pot). I'm sure this is a simple task if you know what you are doing. I do have some very basic electronic understanding, but not enough to design this I'm afraid.
Appreciate any help, thank you.
