Is the control unit for the AQR9 and AQR15 the same? Or are they sized (power supply) for the cell that comes bundled with them? The main reason I am asking is I wanted to get an AQR9 (which should be fine for our pool), but wanted to know if I could upgrade to the T15 cell later, if I needed/wanted to (without having to replace the entire unit). I did notice that they sold the controller as a standalone, noting that the cell was sold separately, but was not sure if that translated to a single controller across their bundles.
