As a researcher I've run experiments that were critically dependant on
maintaining exactly the same temperature over the day. Mild heating was
applied and cooling was achieved by adjusting the sash height. Any
movement of the sash would have changed the temperature and voided the
experiment. That's my vote against equipment deciding what to do on its own.
