For those that need an expansion outlet that can be addressed and controlled by your Aquacontroller, here is another way to do it that is very low tech.  Purchase the following outlet http://www.iautomate.com/pao11.html , replace an existing outlet in the area you need it, set the address, configure your controller and you are off to the races.  If you are not a fan of X10 device's then this may not be for you but if you want to controll a chiller etc., that may be in the garage or outside, this should work.

Good luck,
