Problems to down temperature

Hello! I have a problem with the configuration, the temperature takes a long time to go down, more or less 30 minutes in idling and 3 minutes cooling, which makes it go down 2 degrees late many hours. The control constants I have everything in white. How could I solve this problem ???
Thank you!!

I’m not sure if this applies to your Arduino build but Is there a button to reload default values to the right on the Control Constants header? I would start there.

Thank you for your answer, I have tried what you said and follows the same problem.
Thank you!
