How to time my co2?

[Rasmusm]

Hey

Im trying to understand this new ghl computer I have the profilux plus II.
I figuret out last night how to activate the s1 socket in my power bar, and plug in my magnet valve for my co2 it runs between pH6.95 - 7.00 thats all fine, but it does it 24/7. I use to cut off the co2 duing the nights and then start it earlie in the morning. Is it possible to put a timer on that s1 in the power bar? If yes how can I do it?

Thanks for reading my newbie question :-)
Merry cristmas

There are two possibilities:
- there is a night time option in the Profilux Control menue to set a different/higher value for a spevific time period (preferred)
- program a timer for daily "ON" and use an automatic logic gate to code it as PH1 AND Timer1. You have to assign the magnetic valve to that logic gate then

Thank you, I will check up on it.
Actualy its not bad having the co2 running all the time it seems.

Why not do it like this ?
- don't dose kalkreactor water @ night , since you don't feed new water into the reactor the ph should be 'stable'

It is a fresh water tank :-)

then you need to use the logic Wirus said

Hello Wirus, I am trying to do this as well, I have found with the nocturnal it will only allow a 1 degree shift from normal. I am measuring pH of the water exiting my calcium reactor, which is configured for 6.2, during the evening I would like to pH to go back to normal which is around 8, but in the nocturnal setup, I can only increase by 1, which give me a value of 7.2. how can I change this so that I can get the nocturnal value to 8 or above?

Hello is anyone monitoring this thread?
