Eugene, you can do anything with your profilux. It really is a great piece of equipment. I control my vortech pumps with mine, they are programmed to go into various modes at various times of the day, I think you can do that with your tunze as well. You can get a sms module which will send you sms and tell you what is going on with your tank. I control mine wirelessly via my laptop, changing dosing regimes on my laptop and even place my pumps into feed mode via a touch of a button.
It reads and controls my ozone, controls my temp by switching on fans if the tank gets to warm, etc, etc.
Your plug bar is what limits you, the more plugbars you have the more you can plug into your profilux and its not difficult to programme, I know you'll be fine, I did it without any help (but you have my number bud)
You will love the unit, its worth every cent.
