Here I am reading installtion instructions again. My Aprilaire 600 humidifier was installed with the "outdoor" temperature sensor placed in an inlet air duct (6" diameter, insulated, running about 12 feet to the outside wall).
Will this work OK? Or should the sensor go all the way to the outside.
Also, does the settings nob on the humidistat unit actually change its position with changes in humidification level? I thought I set it at 5 a few days agao and today saw it was near to 3. Or am I just going mad?
Thanks for responses!
