AC Jr vs RK2

first off the AC Junior can control 12 devices and the RK 2 can only control 8.

The AC JR has a ton more features than the RK 2. It has a programming language so it's much more versatile. It also has the serial option so you can connect it to the computer and download logs and control it via Aquanotes. The RK 2 has none of this. Also if you find a group buy you can get the Junior cheaper.

I think that is more than enough! :)
 
Here are the advantages of the Jr over the RK2:

- Can control up to 12 devices. RK2 only controls 8.
- Seasonal lighting variation. Not present on RK2.
- Seasonal temperature variation. Not present on RK2.
- Moon Cycle simulation. Not present on RK2.
- Datalogging of pH and temperature. Not present on RK2.
- Temperature compensation of pH. Not present on RK2.
- Much more flexible configuration on the Jr.
- Jr less expensive $250 vs. $270 for RK2 equivalent configuration.

On the Jr w/ the serial port option these additional features are available (none present on the RK2):
- Computer Interface so that it may be connected to a PC.
- Digital input. (can connect to float switch, water on floor sensor, power fail sensor, etc.)

- With AquaNotes Lite (free)
- datalogs are stored in the database.
- Graph of the datalogs.
- configure controller through PC.

- With the Full version of AquaNotes
- Email alarms.
- Web access of the controller.
- Event logging.

In summary I think that the Jr has many more features than the ReefKeeper 2, and it even costs less.

Just to verify,

If I purchase a AC Jr. with the serial port and interface. Connect it to my PC and have the full version of Aquanotes, I can access data and control items from the web. Right?

(I will be such a nerd!)
 
Yes. You need an internet connection in your house, and a version of windows that supports IIS or the PWS (anything but Windows XP Home edition).
