Rated 2.0 out of 5.0 by SLB Plug-in thermostat switch has limited functionality
I installed this plug-in thermostat switch with a 10" inline duct booster fan in order to turn the booster fan on and off with the air conditioning. The fan was installed in the attic of my town home in order to provide better HVAC airflow to the 2nd floor. In hot weather, the temperature in the attic ranges from 80's at night to 120 degrees during the day. The extreme temperature variations make it difficult to find a setting for the thermostat that will turn the fan on and off with the a/c. So far the thermostat setting either keeps the fan on all the time or fails to turn it on when the a/c comes on.
I have determined that in hot weather, it is advantageous to have the duct fan stay on all the time. When the a/c is not running there is still cool air in the duct work, so having the fan run continuously between the a/c cycles actually helps cool the 2nd floor.
I am considering a bluetooth or wi-fi controlled outlet instead of the thermostat. That would allow me to turn the fan on or off with a smartphone rather than having to crawl up into the attic to adjust the thermostat.

Rated 1.0 out of 5.0 by JM99 Not working well in attic
I installed this thermostat in the attic to turn on my booster fan for the dyer. I've discovered the attic gets too hot and the switch will turn on without the dryer running. Eventually the fan will turn off from the cool air coming from the conditioned space in my house. To alleviate this problem, I turned the temperature control as high as it will go, but now when the dryer is turned on, the air isn't hot enough to turn on this switch.
The bottom line is the I wish I had purchased a booster fan that had the pressure sensor in it and not rely on this switch.
I also don't like that I had to cut a half inch hole in my duct for this switch.

Set up for an outdoor bird cage. The Ductstat turns on a heated perch and a ceramic heat lamp on cold days and nights. Romeo likes it!

The plug-in feature makes installation a breeze for plug fans. The thermostat is very accurate once you've figured out how to set it. Its somewhat confusing on set up. whether to use the cooling scale or the heating scale when setting the on-off temperature.

We had an issue with our lower level rec. room being cold. It is around 1000 sq ft. with 4 heat vents that are placed in the ceiling tiles. The heat not only stayed at the top of the ceiling, but also above the ceiling tiles. We placed 4 , 6in in line duct fans in the ducts, then took an 8in in line duct fan and placed it vertical and taped a piece of screen on the intake (back) of fan and placed the output on a ceiling tile, (had to place a piece of veneer wood to support fan, this fan is used to draw the heat out of the ceiling and blow down, we ran extension cords (since these were all corded), and placed the Ductstat on the heat trunk, plugged into the outlet, then plugged a 6 placed power strip into the Ductstat and plugged all the extension cords in, We turned on the furnace, and regulated the temperature on the Ductstat, it ran all the fans perfect. Living in Michigan the winters are cold and our lower level would be in the higher 50's, With the furnace set on 70, the lower level is now a nice 69, It works perfect. The fans run longer once the furnace blower stops, but that's perfect. Keeps the air circulating longer, we have 2 knee walls that are exposed foundation, which we will insulate soon, that also will help in keeping the lower level wonderful too

You can adjusted properly so don't put it in the attic because you cannot control the temperature

I looked all over for a device to control the ventilation on our hydroponic garden. This was exactly what I wanted. You can set it to come on in rising heat or lowering cold. It controls the duct fans and does what I expected. Down side is I had to order it, It took too long to arrive.
