The Noden Electronic Thermostat is a high-performance electronic thermostat that uses a high-sensitivity, high-precision IC and is easy to use. When used in conjunction with Noden cables or Noden gardening mats, the Noden Electronic Thermostat automates troublesome temperature management and also saves on electricity costs. I used it indoors to control a household freezer. There are no operational problems. (Used about 10 times in total, about 2 weeks each time, and stored in a box when not in use.) I will wrap the box in bubble wrap and ship it. - Model: ND-610 - Color: Red - Accessories: Sensor cable - Power supply: Outlet type 100V 10A Heating and cooling combined Temperature range: 0 degrees to 50 degrees Thank you for viewing.
