The system is a simple temperature controller. The basic idea is to set the temperature in an office based on time and working hours.
The case has been originally taken from a textbook by Michael Negnevitsky, Artificial Intelligence. A Guide to Intelligent Systems, 1st ed., Addison-Wesley, 2002.
The case has been the first HeKatE case to be modelled. It has been described in several papers .
