In HVAC systems, what is the "set point" primarily used for?

The "set point" in HVAC systems is primarily used to control the operation of heating and cooling. This temperature setting is established based on the desired comfort level within a building. When the actual indoor temperature deviates from this set point, the HVAC system adjusts its operation to either increase or decrease the temperature as needed. For instance, if the indoor temperature falls below the set point in winter, the heating system will activate to raise the temperature. Conversely, if the temperature exceeds the set point in summer, the cooling system will engage to lower the temperature.

This functionality is crucial for maintaining consistent and comfortable indoor conditions, enabling efficient energy use and occupant comfort control. The other aspects mentioned, like outdoor temperature measurement, energy consumption assessment, and airflow patterns, do not directly tie into the set point's main role of regulating heating and cooling based on user-defined comfort levels.
