Pool valve X10 automation question

[cswanson2@austin.rr.com]

I have just had a pool installed and I'd like to automate
one of the valves. It is a Jandy Neverlube valve, with a 2" pipe.

The lights are already on X10 from the electrician, and all I want
to do is automate that one valve. I don't want a more expensive
control system, just a X10 interface.

So my question is, I can get the Jandy or similar control actuator,
but what interface does the actuator have, is it a simple X10
on/off singal? How would this work?

Any help would be much appreciated.

Thanks,

Carl

The Jandy valve needs 24vac to operate in either direction. You can use
an X10 Universal Module to operate a SPDT relay that's wired to provide
the voltage to either the 'close' or 'open' lead. If you need a
diagram, let me know.

First, the Jandy actuators are available in EITHER 12 or 24V. Choose. I
prefer the 24V (higher torque, lower amps = less heat and arguably better
life) but either works.

Second, don't do this with X10 if you can avoid it. It simply isn't
reliable enough. You want something with positive control.

If you MUST use X10, a contact-closure module (easily available) will work
along with an SPDT relay to drive the appropriate wires on the Jandy actuator.

Better is an ADICON RLY8XA, which can be driven either directly off
HomeDaemon (see my web page for source that will compile on most modern
Unix machines) or, if you insist directly off X10.

If you get the 12V version of the Jandy, the RLY8XA and the Jandy unit can
both be driven off the same power supply.
