AC Infinity 67 Inline Fan Contoller

Thinking about getting one. Running humidifier and heater in 2x4x5. My averge temp is 75 and rH is 73. I am looking at the controller to smooth out the ups and downs of humidity. Temp is good, ranges from 72-78, light on and off. Humidity (VPD) is my main concern. that can range from anywhere from 65-82.
It seems to me that the controller adjusting fan speed up and down for rH and Temp parameters, would fight for the right settings? Right now I usully run fan at 2-3, EC motor S4 , 8 speeds. Would fan speed controller adjustment parameters mess up my temps? Would temp and rH parameters battle each other???

What are your parameters and experiences with controller?

You could indeed have fighting appliances and controllers. Pick the unit that controls that parameter best and then don't use the other 'competing' device to trigger to it. I love the 67 along with my T6 and S6...but I'm not in need of a heater. I use an Inkbird for my humidifier, then I set my 67's trigger range for humidity slightly outside of the setting of the Inkbird that way if the humidifier goes off the track, there's the fan setup as a safeguard.

I dehumidify outside of the tent, then use my fans to draw in dry and push out wet air.
