I just had my intellitouch upgraded to an intellicenter by a Pentair authorized/certified company. Right before that, the intellitouch and one of the intelliflo pumps started malfunctioning and not usable after a lightning storm. The malfunctioning intelliflo's drive was replaced (it powers the PV3 and deck jets), and it is working fine. The other one (main filter pump) was never a problem and I've been running it manually while the intellicenter install was pending, with no problems.
The pump addresses are correctly set (1 and 2). Both pumps' displays say display not active (ie the intellicenter is in control). However the filter pump, pump 1, has an alert on the intellicenter that it lost communication. What's weird is that it turns on, starts priming, drops RPMs down to the program RPM (I can hear it go from 3450 to 2600) and then about 30 seconds later the pump just turns off. Then if I put it in spa mode, the valves will all turn, that same pump will fire up again, heater fires up, and again 30 seconds after reaching the programmed speed, again it just shuts off. The display on the pump still says display not active. The PV3 pump 2 has no issues at all.
I put pump 2's 485 cable on to pump 1 (unfortunately pump 1's 485 doesn't reach pump 2). The electrician that originally wired it had the 485 cable's spliced together. I undid the splice for testing, put one 485 each on the J4 & J5 comm ports on the intellicenter board. Then I swapped them. Pump 2 works always. Still no luck with pump 1. Neither of the two pumps have 3.03 or 3.04 firmware. They have 2.x (probably the original one they shipped with).
I called pentair trying to get validation that the drive is messed up on pump 1 but they do not believe so. They gave some suggestions and then said wait for the tech to come back out. But I'm not that patient
Any ideas?
Here is a picture of the wiring:
