ECO Jaws Main Unit Only Remote Control

This was originally included with my new house, but I've switched to an all-electric system, so I removed it without ever using it. I'm open to price negotiations as much as possible, but I may not be able to accommodate significant discounts. I've drained it as much as I could, but there might still be a little water left. I also have a gas stove available. The price is negotiable.
