What are the similarities between the S811+ and the S811?

The S811+ is an upgraded version of the S811. Both devices have the identical power structure and base assembly. The printed circuit board and firmware used on the S811+ is new. They have the same (S811+ default) start and stop methods, options, and ratings, and they use the same accessories. The default control terminal wiring is identical, making the S811+ a direct replacement unit for the S811. The S811+ has retained all the features of the S811 and offers an expanded feature set.
