IntelliPh control box down.

Control box not working, read up on @bdavis466 post about wiring through a relay.
I understand the wiring, but my question is:
Can i get the 26VDC from the SWG control board (this is where the PH gets its original power from)on the extra connector of my ET8 with integrated SWG transformer? Dont want to get another transformer. I would get power from the Black- and Red+ to feed an extra relay and program it on an aux with egg timer. I would plug the stener to the load side of the relay.
Thanks

I would have done that if I had a SWG transformer. The relays are pretty inefficient and you might get too much voltage drop. Give it a try and test it with a meter to confirm.

Back up and running! Thanks @bdavis466.
Voltage only dropped 1 volt across the relay with and without load, so that is great.
Wired it to Aux 1. Now i only need to do the math, stener for 60sec fills 300ml/10.6Oz of 15% acid(half dilution).
That is about a .2 drop in PH for my volume(29,000 L/7,661gal). Probably about a min of runtime 2 or 3 times a week, since i have
a fill TA of 120-140 and im on autofill.
Pictures follow, no wiring code so be nice.


And the culprit,
