Hi,

Here's an alpha copy. I am still thinking about...so don't build it yet. I think it should work (I don't have the proper tools to simulate this thing...so I have to do it by hand).

reefburnaby, problem.. I need this to run on 24VAC not dc, I showed it right in my original drawwing just typed it wrong.. sorry..

Hi,

Oops...okay, that circuit isn't going to work. The front end is fairly easy to change from AC to DC. The back end (the driving side) is going to be a bit tricky. Are you okay with relays ticking on and off...or do you want 100% silence ? 100% silence is solid state switches...the other uses relays.

Sorry.

- Victor.

well depends on how loud. if it is a soft tic I don't mind as it will be in a closed stand and I can build a sound box around the valves if I have to.. if solid stait isn't to bad in price then that is ok also

Hi,

Come to think of it...you are going to be running some big pumps in your system. So, you probably won't hear the clicks coming from the relays (they are small relays).

I'll modify the schematic with AC in mind with the relays. Electronic version is available, but parts are hard to get locally (i.e. you'll need to go through digikey).

hey Victor have you had time to come up with anything yet?

Hi,

Its in my head right now...so I have the circuit. I am a bit busy these days...same problem/deadline as Titus.

no problem Victor
