I'm looking for a schematic for a Jandy Aqualink RS 8 swimming pool controller.
It shot craps yesterday and the pump won't shut off.
Of course it's typical American engineering, uC plus hokey "solid state relays": TRIAC in parallel with an undersized mechanical relay, all in one $60 package :-(
BTW, I learned a nasty lesson yesterday... working outside, when it's

Check the triac for that relay, that's what usually goes kaputt. Probably says BT-something on there.
You mean the whole pool timer is only $60? I remember them being sold for ten times the price of sprinkler timers which essentially have almost the same functionality, which is why I ...
Careful, heat stroke can kill you if nobody is nearby seeing you hitting the concrete.
Just the relay :-(
I know. I went inside *quicky*!
...Jim Thompson
Hey, what you did when you got inside is your own business... Best regards, Spehro Pefhany
I knew it. IMHO totally over-prized. I won't use pool timers because I am not inclined to help finance some executive's Lamborghini. I mean, what does that thing do? Turn on the filter pump and a while later the booster pump for the sweep.
Anyhow, if the relay is hanging and it's a module check the triac in there. Unless, of course, an undersized relay has welded shut.

Sno-o-o-ort! Well... it passed the spell checker ;-)
...Jim Thompson
Awwwh! Can't I sell you a chip design to finance mine ?:-)
I hear clicks.
I'm going to replace it "classic-style"... small relay driving contactor.
Tons of room inside the box. Probably was built originally with _real_ relays.
...Jim Thompson
Nah, I just buy my chips at the local store. For example Pringles :-)
That's what I had once when the triac was toast. Replaced it, done.
Then the accountants came and said the gross margin has to go from 90% to 91%?

Monday, 110°F, and I nearly get heat stroke.
Today, cool, so I try to complete my outdoor wiring job... dropped abruptly down to 66°F and just started dumping COLD rain on me :-(
Snow predicted up north.
...Jim Thompson
It's called global warming ...
So, did you get that relay module fixed?
Bypassed it with a mechanical timer so I could get the pool motor running. Ultimately will chain a small relay to a contactor. No more "funny" relays ;-)
...Jim Thompson
Good. Don't wait until algae build-up sets in.
