The gist I'm getting, is the "Transfer Switch" within the Heart Interface unit, is to let it provide 120 VAC from Battery, WHEN there is no 120 VAC Input to the Heart Interface.
In that gist, there is some other, external, "Transfer" to accommodate 120 VAC coming from Either Shore Tie --OR-- Onboard Generator. If this is true, there's a Transfer device of some kind, then probably a Breaker Panel, feeding the Heart Interface unit.
Transfer can be an Automatic Transfer Switch (ATS) --OR-- a Receptacle, usually in the Short Tie Cable Storage area. To do a "manual transfer" the Shore Tie Cable gets plugged into that Receptacle and the Generator is started up. In the following diagram, the Transfer Point is marked "SWITCH."
We need some OP's who have or had BF coaches to help explain how they're set up. Some of the posts here suggest the 120 VAC input is straight from Switch to Heart Interface, so when the Heart Interface detects NO 120 VAC on it's Input, it produces 120 VAC from the Batteries, to AC Out, and the whole coach is served by the Sub Panel. In this scenario, there is no Main Panel.
