Buyer beware…these are not the same as what Pentair sells. Just 32 days after installing I had another E05 error!What makes these sensors inferior to the Pentair brand:1). First the connections covers due not match the OEM sensor wires that you need to connect this flue sensor too.2). Second, the Pentair sensors wires are covered in a heat shield…these are not.3). They failed just 32 days after installing. Check out the top of the sensor.Bottom line I just wasted $18….I guess you get what you pay for with China knock-off’s!Ordering the Pentair sensor!
