Question 436General Subjects - Assistant Engineer

The correct answer is D) The system is a multi-zone system, with one circulating pump and one heating coil. The diagram illustrates a central-station hookup for a hot water heating system, which indicates a multi-zone configuration with a single circulating pump and a single heating coil. This setup allows the system to supply heated water to multiple zones or areas, rather than a single zone as described in option C. The other options are incorrect because option A describes a single-zone system with multiple pumps and coils, while option B describes a multi-zone system with multiple pumps and coils, neither of which match the configuration shown in the provided diagram.
