I have a Compool Cp3600 and I'm getting an Err1 (bad water temp sensor). Looking at the outdoor control panel, the lights are on for both water and solar temp sensors. I checked wiring and things look OK.
i bought a new temp sensor, installed, and it still shows Err1. This is the red/black set, not the red/green. I had the red/green (part number TS-5L) but was told this one (part 520272) was the replacement for it. Also noticed that the size of the sensors that goes in the water is different.
No local place stocks the TS-5L version. Are they incompatible even though they're supposed to be replacement parts? Anything I should be worried about that both water and solar sensor warning lights are on?
thanks for the help.
