Electric fan runs all the time

Quick question for those of you who run a Dakota Digital fan controller. If you disconnect the battery for whatever reason, do the settings for the controller need to be re-entered?

In my case no, all of my settings are saved when the battery is disconnected

I agree, it holds the settings with the battery disconnected.

I’m sure at some point if it sat long enough they might have to be re-entered, but I know I’ve left my battery switch off for days and even weeks at a time and the settings held.
