Re: Pool Valve Control

["BruceR" <brNOSPAM@xxxxxxxxxx>]

Thanks. You've got it exactly right - right down to the part numbers!
The green board was removed from its case (as was the blue board) to put
it all together in the surplus Primestar case.  The setup is about 2
years old now and hasn't missed a beat. The high power relays (aka
contactors) are European and mount on a short section of DIN rail.
They're normally quite pricey but I only paid ~$5 apiece on ebay and the
guy through in a piece of DIN rail for a couple extra bucks.
 The RS485 output on the Stargate controls the relay board. I can send
an X10 command to activate a macro to turn things on and off.  In my
case, P7-On first turns on the spa pump, waits 3 seconds and activates
the valve actuator to send water from the spa through the heater and 20
seconds later turns on the heater. Finally, after a 10 minute delay to
allow the water to warm up, the spa jets turn on. There are a couple
ofhter commands in the macro too.
 When we're done, P7-Off shuts off the jets and the heater, delays 1
minute then closes the valve and shuts off the pump.
