The unit I got last year is completely different than the one it replaced.
First thing to do is check your owners manual.
Second thing is to contact Aprilair.
Third thing is to repost here, with more information on what you have.


It is model number 560, as shown here. They have a humidistat that looks
like mine for $50. I'd guess I need to research it more to see if is
working properly.
