Port B Wiring
Port B uses the 12 position connector. Since all port B inputs are optional the wires are provided with the
connector pins crimped but the wires are not installed in the connector. A descrip tion of each wire and its
function is described below. If you decide not to use an input you may leave the wire uninstalled.
Pin 1 – Water Temperature Sensors – Insert the green/white wire in pin position 1. Connect the
green/white wire to the optional water temperature sensor. This sensor is used to read the actual
temperature in degrees F or C. Do not confuse this input with a high water temperature alarm switch input.
If you would like to use the factory installed temperature alarm switch do not use this wire. See
