Intellitouch panel no leds lit but Reset button turns them on

Hi All, trying to determine if its time to replace the Intellitouch panel electronics. About a month ago after a thunderstorm, my inside wall controller started blinking and making a high-pitched squeal. I disconnected it, planning to diag when I had time. All else was working fine. A week later, the pool pump wasn't running and every led was lit on the Intellitouch panel. Resetting the breakers cleared the fault and returned to the Auto led setting with all equipment returning to the usual schedule. Another week and Texas got pounded by huge storms. The Electronics breaker was popped. Reset it and it stays in but no leds come on. Equipment does not run on time so for the moment I rewired the Pentair VSF pump and SWG direct and they are on their own schedule.

In the meantime, I checked the Intellitouch power supply 12, 18 and 24V are reading 14, 22, and 29 so assume all is well there. If I hold down the Reset button on the Intellitouch panel, the Auto Led lights up and continuing to hold the button results in almost all of the Leds coming on one at a time. When I release the button, no Leds stay lit.

If I'm looking at an Intellitouch replacement, I believe there is a replacement electronic module for this panel that drops into my existing breaker panel. Has anyone does this and, if so, how easy is the reprogramming process? I'll be DIYing this. Pentair notes the following options. "PART NUMBERS 522045, 522046, 523218, 523530 - LEGACY SYSTEMS MANUFACTURED PRIOR TO 2012". Not sure how the options' capabilities compare. I currently use my phone a the Screenlogic Connect app to monitor and control but it's not essential. I just need reliable auto control over all the equipment again, preferably using the inside wall controller for regular use of lights/spa/temp etc, and the outside panel for maintenance settings.

A quick pricing search. I just picked one of the many suppliers here, assuming they are similar in price
522045 $1000 (Pentair IntelliTouch Pool or Spa to IntelliCenter Control System Upgrade Kit | 522045)
522046 $1400 (Pentair IntelliTouch Pool and Spa to IntelliCenter Control System Upgrade Kit)
523218 $1451 (Pentair 523218 Intellicenter Upgrade For Dual Equip System Before 2012)
523530 Didn't find a price

Thanks, Blair

Hey Blair it sounds like the indoor and outdoor mainboards are toast... I "think" I fixed your indoor for you once before... maybe a few years ago?

indoor board:
the "squeal" you're getting happens when the board pulls the supply voltage (black/red on the comm port) below 8 or so volts and the thing can't start up... but - annoyingly - the piezo buzzer will be on. That definitely happens when you have a blown comm chip that is shorted internally, but it can also be caused by other failures or blown components on the board.

outdoor board:
if the leds are acting screwy then it's very likely that the microcontroller is toast, but there's a chance that it's just the comm chip(s) that are dead (depending on the board revision you'll have 1 or 2)... If the board is toast, you would only need the mainboard - the top/personality board is almost always fine.

programming:
If the indoor board can be repaired, a new outdoor board will just pull the programming from the indoor, so programming isn't necessary.

If you want to see if these are repairable, shoot me a pm. I also probably have used replacements that would be a fraction of the cost of new.

Yes Tom, you did fix my indoor unit. Much appreciated and thanks for responding again this time. I'd love for you to take a look at what I have here. Should I just package up the mother and daughter boards from the Intellitouch plus the inside unit and send the whole lot to you? At the moment they are all bricks. I'll PM you for an address.
