#Installation
Hi, I found an issue when I would try to replace old switch with S220.
In which I will put
Old Left L1 (Brown) -> new L1
Old Right L1 (Brown) -> new L2
Old Left COM (Red) -> ?
Old Right COM (Red) ->?
In which the new S220 has only one COM for both left and right, while the old one has a COM for left and right. The above COM also not connected with bridge COM cable. So in this case , please advise how to put the COM cable from old one? put both COM in the S220 COM port?
I will ground yellow to box, blue will put a wire nut.
Thanks a lot
