View Full Version : Program help for Kalk

Anyone know how to restrict my on time for kalk additions?
Unless is there a way to turn off if ph rises more then 1.0 within 1 hr?

This is my programming so far but what has happened is the ph can fluctuate too much. I use two little fishies kalk reactor.

Fallback OFF
If pH < 08.30 Then ON
If Time 18:00 to 23:59 Then OFF
If SwitchA3 OPEN Then OFF
If SwitchA2 OPEN Then OFF
If pH > 08.35 Then OFF

The easiest thing would be to use the Min Time command. Add the following to the end of the code:

Min Time 10:00 Then OFF

This will keep the Kalk OFF for at least 10 minutes before it can turn ON again. Adjust the time as needed.

An alternative would be to use the OSC command in place of the If pH ... ON statement:

OSC 000/10:00/50:00 Then ON

This would dose for up to 10 minutes out of every hour, unless one of the OFF commands is true.

Thank you very much, just what I was looking for, the OSC command will work for me

Yeah I use OSC command and then have a bunch of things that can trigger it to be off. Like float switch in sump, salinity, pH. Multiple levels of protection.
