These kinds of installations are not for beginners. See picWe were very impressed by low level of noise when we first got it installed.
This model is suppose to have a humidity sensor that automatically comes on. I don't see any mention of it here. Does it have the sensor? The QTXE150 is NOT a humidity sensing fan, so it does not have a sensor. The QTXE110S has a humidity sensor. Does this product replace Model s130A? none item dimensions 2 x 2 x 1 ???? none I want same fan but with a light none Does it have a built in damper? All of our exhaust fans include a back draft damper. Roof and wall caps are separate. Thank you.
