"I do not know, but I feel like the fan provided (50cfm) is way too powerful or it does not work. There are times when the 'out' light is on, implying the fan is trying to run, but the fan is not moving. I have tried changing the Minimum Fan Speed UdC, but I do not know how to find the minimum for this fan. The result is that the fan basically operates as a on/off binary state, not variable voltage as suggested by the builder. "

Your feeling is not correct.
OUTPUT is PID variable voltage.
Fan does not run when output voltage is lower than the minimum starting voltage of fan.
Indeed you can forget how it works.
