how to stop the dosing of co2 for 9pm to 8am at night to the CR ?

[chercm]

does this make sense ?

program logic : timer 1 and ph value 1 decrease

timer : 9pm to 8 am

please advice

i assign the co2 plug to socket s4

use the nocturnal change

if the desired value is increased at night you have what you want

It´s an increase not an absolute value you have to enter there ... and ph7 increased by 10 is not possible at all.Use a 3 to get the max ph of 10 you want.

I´m not sure, but maybe the programmers think that a nocturnal change of more than 1 ph is not senseful and dangerous.

Anyway, if you want to switch off ph based dosing in any case, the idea from post #1 has to be used:

program logic (use G1 for example) : timer 1 and ph value 1 decrease, function AND
timer : 8am to 9pm (changed due you want to have it ON during the day)
socket s4 : assign the co2 plug to the used logic (G1 in our example)
