The Eccotemp FVI12 outlet water temperature sensor is only for the FVI12-NG or the FVI12-LP models. It reads the temperature of the water coming out of the unit and is not to be confused with the over temperature sensor.

My temp sensor failed within second year, still under warranty, it was repaced free. Phone technician was efficient, helpful. Temp sensor failed again at about 18 months, right on time. I feel the sensor wire gauge used is too small and the metal of the sensor acts as a magnet for calcium and/or other hard water deposits. I don't like spending $18 for sensor and shipping and regular maintenance required every 18 months, but the unit functions otherwise very well. I wish EccoTemp would engineer sensor using less susceptible metal or some grounding or resonance circuit to make their temp sensor long lasting in hard water areas and use larger guage wires for the 2-wire sensor. Aside from the 18 month cost and maintenance required, I love my FV112 EccoTemp.
