little late on this post but from what I understand, jandy has come up with a inline circuit board to add to the terminal end of the sensor cable that is supposed to boost the signal form the trisensor. It supposedly has corrected a lot of the sensor error codes. I've been through at least 4 sensors with mine. One came dead from the factory. Being a premium priced SWG system, you'd think they'd have a premium product. I wouldn't still own mine had I not been able to find parts on Ebay and other sources. My cell is going bad now and I'm likely going to go with another brand.
