Valves are mounted on a small enclosure now,reason for that is the need of some indication,valve open or not.
So for the 2 head/heart valves there is a led now for each valve.
There are many ways to connect a led to the 230 volt ac of the valves but this schematic one has low power consumption due the use of a capacitor that functions like a resistor for ac voltage ,otherwise you need a resistor , and that resistor can get very hot.
Just connect this builds parallel to the valves,for each valve one ,so in this case I needed 2 of them,later 3 when I start using the water valve also.
By the way the controller has the option to lower the output voltage for the valves ,so to avoid getting the valves to hot you can lower the output voltage for the valves to 170 volt or so,or any voltage that works for your kind of valves.
