Review on Airxcel 81 0980 Manual Bluetooth Ready by John Arrow

Includes everything needed to upgrade my RV AC unit to electronic/Bluetooth control. Remember that it fits the device snugly, especially if you have an extra heating element. Be prepared to remove everything once or twice while figuring out how to put everything in there. Tip: Remove the heating element, install a new control box, and then reinstall the heater. You'll also likely need to remove one or two of the main mounting screws to have enough clearance to move things around. Since you're working overhead, a drill press with the right bits is invaluable.
