timer control

I have a ?. I would like for my ozone to come on for 15 min a day and still controll the orp with ozone. I tried the if time statement just like I have the lights but it does not work. The reason I'm doing this is my orp hangs around 380 and the ozone is set for 350-375 once it made it there it never seems to come down so now the ozone never comes on. I was hoping to have it run at least a little bit for the water clarity.

I just asked a very similar question. It might help you too. Just change a few variables.

This should work for you:

If Time > 12:00 Then OZE ON
If Time > 12:15 Then OZE OFF
If ORP > 380 Then OZE OFF
Max Change 010 M Then OZE OFF

You may want to change the time ozone is dosed or the 380 to some other number.
