The WF-8800 Series and WF-9800 Series are fully compatible. WF-9800 Series units do not use "push-button" remote (manual mode override), since the converter operation modes are controlled automatically. WF-9865 and WF-9875 replacement units use a 20A UL-required power cord, whereas WF-8865 and WF-8875 used a 15A power cord. The receptacle on the distribution center might have to be changed from 15A to 20A, and wiring to the shore cord might need to be upgraded, depending which size wire was used during the original installation.
