I recently finished learning to program a lights-on and lights-off pH dosing periods with the gracious help of Zombie. It works fine, except I would like to have the (lights-on) pH period to run 1-2 hours prior to the lights going on and turn off the (lights-on) pH period 1 hour before the lights actually go off. I am not sure if you continue to use the virtual outlets that are currently being utilized, and use time periods instead?
I don't have very much experience with programming reasonably complex commands in Apex. Any help is certainly appreciated.
I tried to change the virtual outlets programming by changing the lighting outlet command and replacing it with a time period like: (If time 14:00 to 22:00 then ON) for CO2Day
and a corresponding: (If time 22:01 to 13:59 than ON) for CO2Night.
However the pH solenoid would then run without any control!
My current program to adjust pH does not show much separation in pH between Day and Night, however I plan to increase the separation once I get this programming figured out.
My current program for pH is listed below:
Solenoid_pH (Physical outlet)
Fallback OFF
Set OFF
If Output CO2Day = ON Then ON
If Output CO2Night = ON Then ON
CO2Day (virtual outlet)
If pHpro > 6.40 Then ON
If pHpro < 6.30 Then OFF
If Output Light1_I1 = OFF Then OFF
CO2Night (virtual outlet)
If pHpro > 6.60 Then ON
If pHpro < 6.50 Then OFF
If Output Light1_I1 = ON Then OFF
Thanks
