I got a whole-house humidifier when I got my new furnace. The humidifier has an outside temperature probe and sets the inside humidity based on the outside temperature.

Supposedly this will prevent the condensation that occurs and can cause mold and drywall damage when you forget to set the correct humidity level manually.

These are the levels that are programmed into the unit:

Outside Temp/Inside Humidity
40° / 45%
30° / 40%
20° / 35%
10° / 30%
0° / 25%
-10° / 20%
-20° / 15%

I can't wait until we start getting some consistent below-freezing temperatures to see how the system performs.

Going on the first pheasant hunt of the season tomorrow morning. I think whatever I bring home tomorrow I'll toss into the smoker with the ribs I am going to smoke on Sunday.
