Connect the static pressure sensor to the +12, AIN and GND input terminals for one of the analog inputs.
A position sensor allows the controller to determine the current opening size of a curtain, ridge vent, chimney
damper or inlet. If the position sensor has more than two leads, find two that provide a smooth change in
resistance as the sensor is turned. You may need an Ohmmeter to measure this.
