This was quite a pleasant surprise. It works beyond my expectations. Does it all. A lot of utility here. I expect to use in it for many projects. I have used it for heating and humidifying concurrently. At the moment its being used for heating and dehumidifying, but it's utility is most notable; it can be setup in various configurations.

I use this in a greenhouse. Programming is pretty straightforward, just be sure to view the directions for heat and humidity. Seems to accurately alternate between heating and the the wall fan (humidity). Mounts securely to the wall.
