I just rebuilt my complete A/C system, WORKS GREAT...

Now when I select ^defrost mode OR ^defrost/floor board combo mode the A/C compressor kicks on. I don't believe this is suppose to happen.

I need help to fix this issue, Someone point me in the correct direction???????

Thinking is was the controller I changed it out for a different one and same issue occurs.

I circled the mode.........

 

It is supposed to kick on, the idea is that the a/c provides dehumidifying for the defroster. It's all normal, don't worry about it.

 

Got it, thanks.. More that I think about it, it makes sense.....
