I may be wrong, but as far as I can tell, your fan looks to be a generic S&P silent 100 CHZ / Envirovent silent 100HT
If your model is like my S&P, there may be a set of dip switches inside to change the settings, including turn-on delay, overrun delay and humidistat settings between 60 and 90%
Again, I may be wrong, but it sounds as if you have turn-on delay active, overrun set high and humidistat set to 60%
You need to take the cover off to investigate!
