Here are the transitions defined in the diagram:<\/p>\n<ul>\n<li><strong>From Idle to Cooling<\/strong>: This transition occurs when the temperature is too hot.<\/li>\n<li><strong>From Idle to Heating<\/strong>: This transition occurs when the temperature is too cold.<\/li>\n<li><strong>From Cooling to Idle<\/strong>: The system returns to Idle when the temperature reaches the desired level (atTemp).<\/li>\n<li><strong>From Heating to Idle<\/strong>: The system returns to Idle when the desired temperature is achieved.<\/li>\n<\/ul>\n<h3>3. Events and Parameters<\/h3>\n<p>Events trigger transitions between states. In our system, the events are driven by temperature readings:<\/p>\n<ul>\n<li><strong>tooHot<\/strong>: Triggering event indicating the current temperature exceeds the desired level.<\/li>\n<li><strong>tooCold<\/strong>: Triggering event indicating the current temperature is below the desired level.<\/li>\n<li><strong>atTemp<\/strong>: Triggering event indicating the current temperature matches the desired level.<\/li>\n<\/ul>\n<h3>4.

Cooling: The state where the system is actively cooling the environment. Heating: The state where the system is actively heating the environment. Activating: A substate indicating preparation for heating. Active: A substate indicating the system is heating. 2. Transitions Transitions represent the movement between states based on events.

Once the current temperature aligns with the desired temperature (atTemp), the system transitions back to the Idle state. Step 4: Heating Process In the Heating state, the system can exist in two substates: Activating: The system prepares to heat the environment. Active: The system is actively heating the environment.
