Hi,
I have an old Aqualink RS4 that came with the house. It's worked well, but this last week, I first started seeing 3 LEDs under the buttons - so not the button LEDs light up - see picture attached.
The buttons still worked so I could turn on and off the pump from the panel. And the schedule was still working.
Then a couple of days later, the panel stopped working - the display was on but only showed the air temperature - but the buttons didn't work.

I haven't done any changes... I did reconnect the 4 wires at the outdoor controller and that brought it back to the state in the picture - i.e. the buttons work again but the LEDs are on.

Some kind of bad wiring?
I have a SPA side remote that's also connected and that one works fine. But could it be something got reset and they are talking on the same channel?

Regards,
Mike
