No it isn't. Before i replaced it, the heater would fire up for a few secs with heat, then shut off on an AGS LED. Now it's not even firing up.K,
It the heater is still doing the same sequence that it was before you replaced the board, then I would still look at the HSI,,, See my original post #3.
Not "Plug and Play" meaning that I plugged it in and it did NOT work.What do you mean that it wasn't plug-n-play?
What was different?
When you jumped the wires earlier, did you put everything back together like it was?
Did you replace the fuse that failed?
I was only turned it on with service mode, pump on, then heater on....When you turn it on at the automation, the heater goes through the startup and then goes off.
When it goes off, press the Spa On button to see what happens and then turn up the set temperature to 104°.
Yep just tried your idea. Removed my remote's wires, then jumped the terminals directly....didn't work. Nothing happens when I press any of the buttons. Board seems to power up initially (as in my last video), but doesn't seem to stay on tho. Turns right off.
On the brown board in the center, it's labeled fireman's switch.
The red and green wires come from the automation.
When the automation wants the heater to come on, it connects the two wires together with a switch.
You can remove the red and green wires and jump the terminals directly.
Check the fireman's switch fuse while you're there.
Then, try the Pool On or Spa On button.
