The room thermostat scenario expresses a workflow around thermostat installation and use. In this scenario, a person will install a thermostat and indicate who is the intended user for the thermostat. The assigned user can do things such as set the target temperature and set the mode for the thermostat.

The room thermostat is a simple workflow to demonstrate how to use the enum data type. Once the installer has installed and started the thermostat, the user can take two main actions. As a user, you can set the target temperature to a temperature you specify, or you can set the mode to one of four modes: Off, Cool, Heat, and Auto.
