Is there a way to give a finer control to the drum fan, particurlarly at the beginning when a lighter flame is starting to be pulled in the tryer. For sake of an example that this happens at the number 1 on the dial. The finer control anticipated would be amongst the smaller indications between 1 and 2 numbers. Changing the value of the present resistor, blocking the air return path or adapting a TC4 PID control?

Thank you for your time.

Thank you! It's just what I was looking for but with even a finer range.
