Just bought a hw 50. Instructions seem easy enough. Will install Saturday. No detail on what the switch is for on the remote display?
It turns off everything except surge protection. I was told to use it if something went wrong with the unit.
I think it is a generator bypass switch. The EMS will shut down power if there is an open ground. This allows you to "bypass" the open ground fault code when using your generator.
It bypasses a LOT more than the open ground fault. It is much safer to make a "Bonding Plug" to plug into the generator to prevent the open ground fault.
It bypasses ALL safety checks, according to Progressive Dynamics. Here is a quote from their EMS-HW50C installation/instruction Manual:

This switch is located on the remote panel, and allows the user to bypass the computer circuit in the EMS in the event of computer failure, this allowing AC power into the RV. This does not disable the surge protection portion of the EMS; however, all other features are disabled.
Here is a link to the actual manual, if you want to see for yourself. It is on page 2.
