Thanks so much for getting back, Thomas.
I've done more research, and I think I've found a device that I can use for this type of scenario and it's relatively cheap:

I have another question though. On the following diagram, it shows a connection for a Dry Contact Switch. I guess this is a remote switch connection, but where can I buy a very basic one of these remote switchers that will work with this model?
Thanks so much for the help!
