ATO and KALK Programable Logic

[Emperor Angel]

Hi Martin / Matthais

I'm hoping one of you will be able to help me.

I am currently setting up my KalK Stirrer, and am obviously working it alongside my existing Top up solution. Here's what I would like to implement:

If Level 1 was on
And PH < 8.1 then turn on socket 1 (KALK Pump)

If Level 1 was on
And PH > 8.1 then turn on socket 2 (ATO Pump)

Is this at all possible using the GHL Programable logic?

Thanks for your help

You pretty much answered your own question loll

Programmable Logic 1
Input 1 = Water 1
Input 2 = pH-value 1 Decrease
Function AND

Programmable Logic 2
Input 1 = Water 1
Input 2 = pH-value 1 Increase
Function AND

Make your ph nominal value is @ 8.1 and your are set to go.

Excellent - Thanks Kidney!!!!

Now, to challenge you.

My ATO pump is 700L / H, thus I want to set a maximum time socket on time to 30 seconds (I have had two float level switch failures, and see this function as a must!!)

But when using my Peri Pimp (Kalk), I want to set the maximum on time to 3 hours?

Is this at all possible?

Alternatively, I would like to schedule when my ATO happens?

Thanks for your help.

Some warnings between to:

"But when using my Peri Pimp (Kalk), I want to set the maximum on time to 3 hours?"

If you use the DosingPump form GHL for your Kalk never let them run so long (3 hours) The pumps are not made for constant use. Maximum is: run = 15 min stops at least 15 min.

It's not the GHL peri pump - My GHL peri pumps are only used for Grotech dosing (A, B, C).

Do you know if there's an availible soultion for the above?

Alternatively, is there a way to set times as to when ATO will happen?

[Matthias]

there is a setting "ATO is only active with timer ..."

-> chose a timer, then set this timer as needed

Awesome - Thanks so much Matthias.

I'm so happy I chose GHL as my aquarium computer, not only is it a great controlling computer, and the product development is zooming ahead, but also the customer service is FANTASTIC!!!!

Having a forum like this is invaluable! And shouldn't be underestimated by GHL.

Thanks once again.

I tried this but found a problem: if pH equals setpoint nothing happens and after a while I get a Water1 alarm (because none of the sockets turn on). I need a way to set the condition: EQUAL
