Carbon dioxide sensor gives the CO2 reading for the room
This is the measured room temperature
Temperature reading needs to be between these two setpoints

This graph shows the different temperature values in the last 24 hours. Zone Temp: the actual temperature in the room CoSp: temperature setpoint above which space will be cooled HeSp: temperature setpoint below which space will be heated SA Temp: shows how the system is adjusting the delivered air temperature to meet those setpoints

Now that you've been introduced to VAV boxes, Let's start with the diagnosing scenarios!
- These exercises are self paced, so no need to feel stressed
- The red rooms indicate rooms with issues, while the green indicate rooms that are working properly.
- Diagnose and solve all the red room scenarios in numerical order, starting with Room 1
- Once you have completed all the scenarios, you can come back and retry previous ones

Notice how around 9 PM, the systems heating and cooling setpoints change and stay at this different value until around 6 AM?
Learn why!
This behavior is due to scheduling through a setback strategy. A setback is a control method in which technicians adjust system setpoints during unoccupied periods to facilitate running less. In this case, the cooling and heating setpoints are shifted farther apart during these hours, reducing the likelihood that either heating or cooling operation is required.
