Dosing pumps on timer

Hello,

I just got a 3 pump doser for my Profilux II with which I want do dose Ca, Kh and Mg on different times during the day.
The 3 dosing pumps is setup on S19-S21.
I want all three pumps to dose 400ml pr day initially.
Pump 1 dose Ca between 23:00 and 02:00
Pump 2 dose Kh between 07:00 and 10:00
Pump 3 dose Mg between 13:00 and 21:00

Timer 1=23:00 and 02:00
Prog. logic:
Input 1=Timer 1
Input 2=Dosing pump 1
Function=AND

Timer 2=07:00 and 10:00
Prog. logic:
Input 1=Timer 2
Input 2=Dosing pump 2
Function=AND

Timer 3=13:00 and 21:00
Prog. logic:
Input 1=Timer 3
Input 2=Dosing pump 3
Function=AND

Extras->Dosing pumps:
Dosing pump1:
Rate/Dosing (ml) set to 400ml
Dosings/day set to 2

Dosing pump2:
Rate/Dosing (ml) set to 400ml
Dosings/day set to 2

Dosing pump3:
Rate/Dosing (ml) set to 400ml
Dosings/day set to 8

Will this work as I expect?

maby but there is a easier way :P

if you set your pump to auto (and it's calibrated), all you have to do is set the amount you want to dose daily, the Profilux is smart enough not to have all 3 pump running at the same time.

Thanks, but it seems like its not smart enough to dose within the time frames I want to dose:o

I solved the issue by using timers set to dosing and specifying on-switch for the pumps in seconds.
Calibrating my dosingpumps shows that two of them delivered 52ml/min and the last one 49ml/min.
Using timers gives me 100% control of the dosing schedule and I`m very happy :-) (allthough I have to bring up my calculator instead of just typing how many ml`s and when.. )
