I have an ACJR & RKL so i'm not sure about any other model, but both max out at 12 outlets. the RKL outlets come in 4's so yes you can run 4 plugs upstairs, if you only need two up there though you have wasted 2 "precious" outlets and it cost you about 140 bucks with exchange and shipping for the 4 outlets. Same deal with the ACJR, except it cost ya 20 or 30 bucks more.

WOW, I cant belive it didnt censor "horse*****" The other name I use for them is kellum grips

Oooh ya, ill change that... Get so used to it at work I forget hehe.

Hello,

I have an Aquacontroller III and it is upstairs with my display tank and my sump and fishroom is downstairs. I have 8 outlets controlled upstairs and 8 outlets controlled downstairs. It just uses a regular phone cable (I bough my 20 foot phone cable from Home Depot). I ran the phone cable beside my plumbing that leads to the basement and put the other 8 outlets (DC8) in the basement. So from upstairs I can turn my fuge light on, or my return pump on or off, or control my calcium reactor etc....

I hope this helps. All it was for me was a long phone cable that did the trick.

Good to know. Thanks
