Quick question that I am sure someone here can answer.

I have downloaded the c monster app for my power poles. 1.0 pumps. I would like to adjust the speed to be a little bit lower than 50% but when I move it to what I want it to be and then go somewhere else in the app to do something else I go back and it’s back to 50%. Is there a way that I need to save the changes for the speed or what?
