Hi,
I have the same Chamberlain yellow button garage door as you and wanted to use the Zen16. I was going to use this switch but keep my current switch too.
Security+ 2.0 Wired Dry Contact Adapter sku 883LM-DCA
But I'm a bit confused on the wiring. This switch works with Security 2.0 doors. Can you give a detailed explanation of the wiring from this switch to the zen16 and then to the garage door opener? Thanks.
