Which system allows individual control of temperatures in different rooms?

A zoning system is designed specifically to provide individual temperature control in different rooms or areas within a building. This system utilizes multiple thermostats in conjunction with dampers in the ductwork, allowing for tailored heating and cooling based on the distinct needs of each zone. This capability enables occupants to maintain comfort in varying spaces, optimizing energy usage by only conditioning areas that require it.

In contrast, a VAV system (Variable Air Volume system) primarily adjusts the volume of air delivered to various spaces based on the specific cooling or heating demand but may not provide the level of individual temperature control that a zoning system offers. Radiant heating systems typically focus on heating surfaces or objects rather than providing centralized control for multiple rooms. A packaged unit system usually involves a single unit that conditions air for an entire space and thus does not allow for localized temperature control.

The distinction lies in the zoning system’s ability to effectively manage temperature in separate rooms, tailoring comfort to individual preferences or needs, which is the essence of its functionality.
