Abstract
A zoned variable volume system is provided with a pair of non-connected dampers in each zone. The first damper controls flow through a cooling coil. The second damper controls flow through a heating coil and provides heated or neutral air depending upon whether or not the heating coil is actuated. The fan speed is adjusted to cause at least one damper to be fully open so that the system operates at a minimum static pressure. The system is adapted to provide tenant metering by determining the amount of conditioned air provided to each zone. Each zone is controlled through a single temperature and flow sensor.
