[TT Riing Plus controller warning message]

Hello all, just joined glad to be here.

I have a little issue I hope I can clear up. If I have less then 5 fans hooked up to 1 controller I get a warning message for that controller. Is there a way to get rid of the warning message.

I installed all 5 fans to 1 controller and no warning message, but I will someday hook up the TT Floe Riing 280 and I will have to use a 2nd controller to hook the water pump to, and I don`t want to see a warning message every time the software starts.  

Thanks for any help.
