We have a factory installed Truma Adventa with both the panel and the remote. We never use the remote and have found it glitchy with poor connectivity. It has to point directly at the ir receiver on the Truma, it often seems out of synch with the wall panel and the time is never correct for long on the remote. However, You cannot access the dehumidification mode on the panel, only on the remote. We don’t use the dehumidification mode any more because it turns the trailer into a meet locker and we now use a small countertop dehumidifier.
Maybe we would have a better experience if we used the remote regularly instead of occasionally.
Just one man’s opinion!
