I have an original Aquacontroller. Bought back in 97 I believe. Still works great, virtually unlimited programming capability....
For instance, i have mine controlling the entire system - lghts, main pumps, powerheads, dosing pumps, CO2, chiller, cooling fans, etc. Programming allows personal set-up - if temps gets too high, start shutting off lights, if pH rises too high, shut down kalk dosing, initiate freshwater dosing, etc.
Always had great support also..
