x10 for valve controls

[rrands]

MrDuffin:

I don't think the idea w/ the 3 way light switch will work - for the x10 to work, it has to be on my home wiring - the voltage I am trying to switch is 24v AC, so if I hook that up as you mentioned, the x10 transmitter has no way to talk to the switch to turn it on/off. Does that sound right, or am I missing something?

I did get this figured out - I got an x10 110v outlet and a SPDT relay w/ a 110v coil (gotta love Fry's Electronics!). I plugged the 24v AC Transformer into the unswitched outlet on the x10, and wire one leg through the relay (1 - NC, 1 - NO), and the other directly to the neutral on the valve actuator. When the x10 outlet is off, it turns the valve through the NC side of the relay. When I turn the outlet on, it turns the valve the other way through the NO side of the relay. Seems to work OK, but I just have it running in the house so far, I haven't installed it at the pool yet.

Thanks for the help!

You are correct.....I missed the part about the 24 volts.
It sounds like you have things under control....(pun intended)
