I bought Lumea C-L dimmers which work great. However i have some lights which need to be controlled from 2 locations, and I was told I can't have 2 Lumea C-L Dimmers and one of them has to be simple 3 way switch without dim functionality. My question is 1) Is this true 2) If it is true, can then the dimmability function on Lumea C-L Dimmers can be disabled 3) If 2 not possible, what are various models of Lutron 3 way switches without dimmability which look similar to lumea models Thanks a lot!
