For anyone that has an Aquacontroller or Jr.

What are the biggest advantages/disadvantages?

Can you run 2 heaters on either...The description on all the sites can be confusing.

I have the AC3. You can run 2 heaters. You could run 2 on the same socket if it didn't excede the maximum amps, or you could program two sockets for heaters. I love my AC3. The only disadvantage is the cost. Neptune has superior service. They can help you get the controller set up even if you're not terribly computer savvy.

you can run as many heaters as you want up to the limit of plugs that you have and you can also use it for your lights, ect

Cool. I couldn't remember since I looked at some other controllers. Some only allowed 1 heater and 1 chiller.
