So dehumidifiers are ****ing digital now ? What is next, bath towels ?

electronically controlled units work much better than mechanical humidistats



If you need to keep humidity to within a fraction of a percent perhaps, but in my experience, electronic controls add complexity and complexity means trouble.

If this dehumidifier was used to keep someone's basement dry and sweet smelling, it would be far better off with a quality mechanical humidistat that kept the humidity within a few points either way. As it is, the poster mentioned that this needed tact switches, something a mechanical unit wouldn't have.
