Navien NHB and NCB System Outdoor Temperature Sensor & Wire

This outdoor temperature sensor plus wire functions as an outdoor reset for the NCB and NHB series units. The unit is water-resistant, but should only be installed in areas where the sensor is protected from direct drenching from rain, such as under an eave.

You can use a longer wire with 18 gauge wiring (thermostat wiring) with no splices, except at the unit harness connection with the yellow leader wire.
