I am working with an architect to build a small (390 sf), 3 room pool house. Tee building will be detached from the main house. The owner wants to be able to condition the space, but wants it to be quiet. The space has a 2 larger areas to each side of the door with a bathroom in the middle. I was thinking I could drop the ceiling of the bathroom and use that space for a plenum and install a through the wall heat pump. Who has that kind of equipment that would allow for a remote thermostat?
