pH & timer control- what am i doin wrong?

[hipman]

:o :o
I'm trying to control my calcium reactor to switch the CO2 on/off with reference to the pH in the reactor - using the "program" from the pH probe menu.

I also wanted to put in a "timer" so that all was swithced off at night.- used the program from the power bar / timer menu.

I can get one - the ph, to work but not the other - looks like the pH is overiding the timer -

(- to top it off was not too chuffed when solenoid stuck on over-night.:mad: :mad: )

Any suggestions wud be appreciated.

thanks

In the pH program change ref to curve and then go across to the wiggle line and set the pH high during the night. So it doesn't kick in the CO2.

Remove the power bar timer program.
