Delta Products Corporation Delta BreezSmart SMT150D 150 CFM with Adjustable Speed Control and Delay Timer

The fan is great and works without issue. There are a few things to note. The dual speed version requires 2 electrical lines running to the fan to take advantage of the additional features. Otherwise you can tie the mode wires to the standard incoming lines. This would mean the blue to the black wires and the white to the white. Also, the exhaust port on this unit is 6” in diameter so depending on your home you may need a 6” to 4” reducer to make the connection properly. All in all the unit is great, just make sure you plan on a potential trip to the hardware store for the reducer.

Extremely quiet even when on high (150cfm) Pay attention to the wiring directions. Requires two separate "hot" wires if you want to utilize full function.
