Thank you for viewing. This is a timer thermostat that can manage the thermostat and lighting timer for reptiles and amphibians. Includes instruction manual. No box. I used it for about 2 years previously. I kept it thinking I might use it again, but I've decided to sell it since I won't be using it for a while. It was used before, so there may be some minor stains. Please refrain from purchasing if you are concerned about this.
