In order to prevent excessive strss on the mounting screws support the DuctStat® unit when unplugging connected devices.
DO NOT use the DuctStat® outdoors or in damp locations. DO NOT use the DuctStat® in an attic or crawl space.
The DuctStat® is intended to control the automatic on/off operation of In-Line Duct Fans™ installed in the ductwork of forced air
distribution systems.
The DuctStat® can also control the line voltage to any electrical device with a maximum current draw of 5 Amperes.
The DuctStat® is equipped with an external, replaceable 5 Amp fuse to protect the electronic circuitry from overload or short circuits.
This unit is equipped with a three-prong grounded plug. DO NOT attempt to defeat the ground feature of this plug. Defeating this will

3. Drill a hole in the air duct for the Air Intake Hole shown on the template. This hole should be ½" in diameter.
4. Drill holes in the air duct to line up with the appropriate holes located on the template. On round ducts, two screws
placed through the slots in the DuctStat® unit's base will be adequate (placement shown on template).
