2. Remove the existing humidity sensor by grasping the tab on the humidity sensor holder
and pulling straight up.
3. Remove the humidity sensor O-ring.
4. Snap the new humidity sensor PCBA into the humidity sensor holder. Please note that
the PCBA and the humidity sensor holder are keyed, so that there is only one way to
snap them together.
5. Place the new humidity sensor O-ring into the humidity sensor recess on the bottom of
the WSO200, centering it on the raised rib.
6. Plug the assembled humidity sensor cover and humidity sensor PCBA into the humidity
sensor recess on the bottom of the WSO200 until it is completely seated. Please ensure
that the pins on the humidity sensor PCBA plug into the connector inside the WSO200.
Also, please note that the humidity sensor cover is keyed so that there is only one way
to plug it in.
7. Place the two screws into the screw holes in the humidity sensor and tighten until snug.
