Is my solution right?

Heat pumps are common in most Europe homes and are used to heat the house in winter and cool the house in summer. The pump comes with a setting control that compares the temperature in the room with the current temperature if it is less then it warms up the room else it cools it. Then set the air temperature you wish the room to be maintained at. Draw state diagram( include states and events of the transitions) Compare temperatures IF room temp>=current E room temp
