We have occasional power outages and/or voltage fluctuations and as this is a new installation we are at times confronted with "new, challenging learning opportunities".
Enter a new one, "Alarm, Power Off - F90052"
All keys locked, no reset... nothing. Reset main breaker, nothing except flow direction valve changed position and then went back to original direction.
I should mention we have a chlorinator and a solar heater and this valve controls the flow to and from the roof heater coils.
OK, how do I reset my desktop after an unresolved problem - turn everything off for a couple minutes and let things reboot on restart.
The trouble shooting guide mentions the system should reset itself in something like 20 sec. after the initial fault trip is resolved but apparently not always.
Anyway, the two-minute timeout worked like a charm. All programs are in non-volatile memory so she was up and running.
Thought this might help as it is a quick fix rather than heading for voltmeters and such... though I can imagine this might be a necessity under certain circumstances.
 
I do not know (re: via filter relay load terminal).
However, if I energize the main pump breaker, the pump is not powered on. The Chlorinator timer relay must be turned on for that to occur.
The solar heating circuits are also energized at the same time. Sort of a cascade effect. might this present a problem or is it just a series circuit "thing"? (high tech reference)
I suppose I should examine / familiarize myself with the circuit diagrams.
Interesting question though.
Do you know any way to remotely monitor, via the solar heating sensors, the pool water temp.?
Some way to tap into the sensor signal and transmit it wirelessly? Tech says they do not have that capability at present. Just asking.
Thanks

As James indicated, Intelliflo pumps are designed to have power all the time. Direct scheduling and/or automation systems are then used to determine when it runs using data, not a power source.

If you have timers or other interlock devices installed, and they kill power to your pump, it will throw an alarm.

It worth noting though, that while this isn't the way Pentair designed them, it won't hurt the pump. This is confirmed by the Pentair reps we work with on warranty issues.

Is this power loss occurring at undesirable times? A new issue? Or is this possibly just a recent observation of the system operating the way it was intentionally/justifiably designed in your case?

J - Under normal circumstances the power to the pump is never really shut off so no alarms when the Chlorinator cycles - same with solar heater. This recent alarm was, I am pretty sure, the result of a power system problem. We are in Vero and since the latest hurricane FPL has been doing extensive repairs and upgrades. This has resulted in some occasional fast cycling power outages - a true pain in the patoot. I have taken to large capacitor bank to protect computer and electronic systems. So far, no apparent damage to pool equipment or controllers so we'll just live with things as they are.
gc - Your comments reflect precisely what our installer has told me regarding configuration. As to timing of occurrences - see my comments to J.
Thanks to you both for your thoughts and insights... much appreciated.
System based remote pool temp sensing... any thoughts?
