These air and water sensors, available in multiple lengths, are designed for marine air conditioners and feature an RJ11 connector. When connecting to certain boards, an adapter (60-6005) may be required to interface with the 2-pin Molex port. Ensure the board is configured for 3K sensors by keeping the RES SEL JP5 jumper in place, and remove the CW JP1 jumper for chilled water air handler applications. The 3K sensors use a 4-pin RJ11 connector, unlike the 6-pin version for 10K sensors. Sensors are sold individually; images show reference setups only.
