I have the Honeywell vison pro IAQ stat and use the humidity control. It has an outdoor temp sensor. I understand the concept of why the sensor enhances the humidity control. My question pertains to the frost setting scale of 1 to 10 on the stat when you go to check the humidity.
I can't find any examples of how to set the scale. I know that as the temp outside gets colder you want the humidity to decrease to prevent wet windows etc. How does this scale work? Anyone know or can link me to the explanation of the scale of 1 to 10? The scale is now set in the middle(5), and humidity set at 50%
