would have been used for research

We have one of this. It works great for temperatures above 22C (I mostly use it for bacterial cultures, which need to be at 37C). However, the temperature has never gone below 22C. I thought I could use it to incubate certain organisms that need to be at 15C but the temperature just will not go below 22C. The manual that comes with it is useless as there is no troubleshoot, and there is no explanation of each one of the controls on the screen. We had to figure that out ourselves.
