Okey, thank you very much for reply !
So, I don't have XS10 port, I have a older version of IRC5, like this:

I don't know why but when I have opened controller, then I saw that I have connected 24 V to pins 41 and 42, but I don't know where those cables come from because there are tons of them and I don't want to disconnect it. Can I just connect 24 V from pin 41 or 42(dont know which one yet) to "+" on solenoid valve, guide it through the rest 3 valves that I have and to the "-" on valves connect digital outputs from IR5 ? I have to add that I have to control each of those 4 valves separately.
Regards.
