+We can now create a {\dc} for the standalone temperature controller, and give it the name TempController.
+It will have the following failure modes:
+
+$$fm ( TempController ) = \{ ControlFailureIndicated, ControlFailure, KnownIndicationError, UnknownIndicationError \}$$
+
+
+We can now represent this failure mode analysis as an Euler diagram, see figure~\ref{fig:euler_temp_controller}.
