    Default PH control for calcium reactor

    Hi,

    I'm trying to set the next thing up, but somewhere I must be doing something wrong:

    The goal is te read the PH in the calcium reactor with a nominal value of 6,9 and a hysteresis of 0,4
    If set these settings in the PH-value 1, sensor is active, no nocturnal change, alarm on with deviation of 1,00 PH.

    Switch channel 3 is the socket that has the valve to open the CO2 in order to decrease the PH.
    Settings in switch channel 3 are function ph-value 1 and functional parameter decrease.

    In my thinking this should activate the socket when the PH reaches 7,1 PH and should deactivate when at 6,9?
    Am I correct with this thinking?

    However the socket remains off, no matter what happens.

    What I did to test before I put the sensor in the reactor is putting the sensor in my tank with nothing connected to the socket (just to see if it turns on and off when desired):
    My current PH in the tank is 8,36. I've set the sensor to nominal value 9 (which should activate the socket): nothing happens, remains off.
    When I put the nominal value at 7,5 to check the opposite, nothing happens neither, also remains off.

    So I guess I'm doing something wrong?

    thx, Yoeri

    I think i found it.
    There’s nothing in my GHL to set control.
    On the box itself there’s an extra functionality.
    The control was set to off. Now I set it to two way control.
    I hope it works now. Nothing in the manual about that.
    In general I think the manual is poor

    Yes, with two way control it works like you want it. This should actually be the default value.

    Thank you Thilo for the manual.
    I actually still had the profilux 3.1 manual, as this is the one I'm having. But I think the manual for the profilux 4 that you've provided is far more complete.
    Thank you...
