View Full Version : High PH to turn MH Off - Question

11/15/2006, 07:00 PM
I have a program set that when my ph rises too high my MH's will go off. My question is once the PH gets back to a set limit how can I make them come back on? If I do another program stating if PH is lower than 8.5 or whatever the lights would stay on.. Right?

Just set ph program to turn MH's OFF if PH > 8.5
The lights Timer program will take over once the PH is less than 8.5, so at night the lights wont come back ON but in the Day they will. (you get the drift)

Thats the way I have it and they dont come back on. The Light Icon Still has the PH logo above it but the PH is well in the safe range....

Oh I think I got it... You usually use the keypad if I remember correctly, I use the PC interface. I just looked and the interface added it's own max min and that is messing it up... I just changed it thru keypad works okay!

No prob, now you know why I use the Units interface so much ;)
