This was a first for me so I need to know if this is standard practice. The kitchen, laundry, bath and master bath bath exhaust fans were actually a timer device which operated the blower which pulls air thru the HRV. Owner stated that a humidity sensor reads the air and if it contains high moisture content, exhausts the moist air out of the home. Otherwise it cycles it thru the return ducts.
Does any of this sound right? I have very limited experience with HRV, but I cannot see cycling momma’s burnt dinner smoke thru the return register into the HRV and back into the home?
