I wasn't sure what VTS was, so I googled it, and the first article that came up for me was discussing what a nightmare VTS was, with water penetration into multiple items, from switches to the VTS motor itself. I don't know how current of models he was commenting on, but it did say that the earlier ones were worse. Couple questions, have the water related issues been pretty much resolved by now, and as I have an IBR 2014 HO model, would it be something that is retrofittable, and if so, would it be worthwhile to do so? Thanks for any thoughts.
