Firefly control center climate sustem

I have a 2017 Tuscany MT44 and for the life of me can not figure out what the "Climate- system" on the firefly controller does. Under climate, I have front, mid , rear, bay and system. All areas function properly for the 1st four listed, yet when I go to system (with the aquahot on) nothing happens. Raising the temp above current temp will turn on circ fans which you can hear running for all areas with exception of the System mode, just nothing happens. I have also never heard the circ fan in the water tank bay area come on. Could the system mode be for the water tank area? Should the tank area fan come on when the bay area fan does? While under warranty, at the factory they had to have firefly come out and reprogram the system to get the Bay circ fan to work. I wasn't aware that the tank bay fan wasn't working at the time, so it could be a matter of reprogramming the tank bay also. I'm just curious to know if someone with the same couch can answer my questions or how their tank bay circ fan works.

I have Firefly system on our 2017 Thor Venetian and at first could not get it to activate the rear ac unit. The dealership and Thor were not useful, so I contacted Firefly directly. They were very helpful and sent out a couple different parts which I easily swapped out and figured out that one part was simply defective. Give them a call and hopefully they can help you.
