That is correct. I have the "no remote display" model and mounted it under the drawers in the galley. I cut a 2"x3" hole in the panel in front of the EMS, installed a wooden switch cover and lexan sheet over the area so I can look into the "window" to see the display. For us, the trailer control panel is at the head of the stairs, about 20' away from where the shore power enters the trailer, so running the remote display wiring was not something I wanted to do and I didn't want "two places to check stuff" so I didn't want to spend the extra money for the "remote display model" and install the remote "in the galley. For us, it works, for others, it may not.

Here's a couple of photos of our EMS window to the display.
