Looking at the CircuPool Si series I notice several similarities to the AquaRite series. They aren't exact matches, for example the status lights are in a different position, but many many things are remarkably similar, including the diagnostic display sequence. I'm starting to wonder if the CircuPool Si series is a rebranded AquaRite?
From what I've read and having talked to compuPool, The RJ series of CircuPool swgs were made by CompuPool. And the Si may still be made by them, tho they say no though the manufacturers are both in Australia from what I understand. JB is correct about the control box having the same logo.
I honestly believe The control Modules are exactly the same for all Circupool Models See this email I received before I actually received the system:
"The manufacturer has contacted us to let us know that the cell type on your system may need to be changed to fit with the 2014 software. Please make sure you check the cell ID after the unit has been installed. You can do this by pressing the system status button on the front panel 8 times. Below are the instructions:
1. Turn power on to the control unit.
2. Put the Super Chlor switch in the ON position, which is the middle position.
3. Press the system status button until you get to the cell type setting.
The cell type should read one of the following:
Si15 = F-9/Si20 = F-9 /Si30 = F-9/Si40 = F-15
Si45 = F-15/Si15 Plus = C-9/Si20 Plus = C-9/Si25 Plus = C-9
Si30 Plus = C-9/Si40 Plus = C-15/Si45 Plus = C-15.
4. Once the cell type is displayed, use the super chlor switch to change the cell type if necessary by moving the switch from the ON position, to the AUTO position. (Instructional Video link:

5. The cell type will change as you move the switch from ON to AUTO.
6. Please make sure your system is on the correct cell type.
Si15=F-9
Si20=F-9
Si30=F-9
Si45=F-15
7. Once the correct cell type is selected, turn power off completely to the control unit and back on the reset the system." Mine was different than specified, but easily changed.
