I have an in-ground pool that we built about 11 years ago with an Aqualink RS8 control system with an All Button in house control. The system also has an 8-button SpaLink remote that is working fine (displays temps and buttons all work) and is about 6 years old. Two years ago I upgraded to an iAqualink compatible system board (rev R) that is also functioning properly and has never caused me any issues.
The strange behavior I'm observing (which started sometime during the winter months) is that every day or two, seemingly in the middle of the night when all devices are off, some combination of the AUX4-7 buttons will illuminate and become inoperable. I only have AUX4-5 actually connected (pool and spa lights) and the others are not connected to anything. Once it gets in this mode, I basically need to power off the system and then everything will start back up properly, until a day or so later when it gets back into this strange mode.
It seems to be a random combination of the AUX4,5,6,7 lights that come on. For example, when it happened today all 4 of them came on. When they come on, they don't also turn on what they are controlling (lights don't come on) - they are just inoperable until reset. Touching the buttons does nothing. Trying to toggle the buttons using the iAqualink interface also does nothing.
BTW, when I cycle through the diagnostics on the All Button system, it lists out everything that is connected (CONTROL PANEL #1, SPA LINK #1, iAqualink Wifi #4, AIR SENSOR OK, WATER SENSOR OK, SOLAR SENSOR OPENED) - I don't have a solar heater so not sure if that solar sensor message is to be expected.
Any thoughts on what might be going on?
Thanks so much in advance.
