Help UPB WAF Emergency

[dBeau]

Great, I was considering 'upgrading' some SAI switches to PCS but alas I have a Pentair variable speed pool pump. It sounds like changing to PCS may not be such a great idea,

I can confirm that the pentair variable speed pool pump does not interfere with my SAI switches. Now since closing down the pool for the winter, I've installed a couple of PCS devices. I guess I'll have to wait until summer to see if there is a problem!

Yea, it doesn't affect my SAI switches either, well, other than putting like 4-6 points of noise on the line. I do have a PCS switch but its currently on a flourescent. I'll have to move it to an often used dimmer and see what happens. Only thing is it sounds as if its not consistent on all devices, and right now the pump only runs during the day and lights are not usually on then. But I am planning on automating the pump to possibly run on real low speed overnight so we'll have to see. Maybe I will just need to program the pump to not run from around sunset to midnight which is when most of the lighting is used.

The folks in this forum run into everything! We have seen UPB issues created by the Pentair Intelliflow variable speed pool pumps. They are pretty nasty in terms of polluting the powerline. One of our dealers in CA uses UPB in his pool installation and service business and runs into this. He has had good success applying a large capacitor (Digikey part # P9412-ND) across the hot terminals of the pump. I have not tried this myself as we don't run into many pools here in Colorado, but I have passed this tip onto a couple of other dealers of ours who tried it with good success.

Apparently, it does not completely remove the noise, but it attenuates it enough that Gen2 UPB devices work very well. You would want to get it close to the pump and as far away from a breaker box as possible, as this capacitor could attenuate valid UPB signals.

So, just a suggestion even though I can't vouch for it myself.
