UPDATE 5/27/2025: Only lasted one day after opening the pool for the season. Now throwing an error. Unfortunately these third party items are not reliable, will have to buy directly from Pentair.Installed the Flue Sensor just before closing and it seemed to work OK, it did not throw an error. Will see how it holds up after opening my pool in the spring.
