I want to set my kalkreactor mixing pump to run for 2 minutes every 3 hours. Rather than taking up several lines of programming said:Wouldn't it be something like:
OSC 180/2 ON/OFF Then KALK OFF
KALK OFF is the initial condition for that DC8 plug when the controller is first powered on. It will wait 180 minutes before turning the reactor on for two minutes.
I would also add a "safety" line to the end like this:
IF PH > 8.3 Then KALK OFF
That way the Kalk reactor doesn't even turn on to begin with if the PH is too high. Aquacontroller rules are applied in order, so I put the "safety" lines at the end of the program. (i.e. heaters and lights shut off when the temp is too high, fans shut off when the temp is too cold, etc).
I hope this helps some, setting up a kalk reactor is a tricky thing.
