(Normal Operation: Cooling with Hot Water Reheat)
Normally-Closed Damper, Actuator, and 3011 Pneumatic Volume Regulator
(Direct-Acting Thermostat)
PC04 – VCCF and VCWF - Single-Duct Terminal Units
With an increase in room temperature, the thermostat output pressure is increased. This signal is input for the volume regulator, which
also receives inputs from the high- and low-pressure sides of the flow ring. The volume regulator outputs a signal compensated for
changing duct pressure to the valve actuator which opens the damper and increases primary cooling flow to the space. With a
decrease in room temperature, the opposite action occurs. Minimum and maximum primary airflow settings are maintained by the
volume regulator. When the system is designed with reheat, heating stages are energized at the appropriate pressure settings.
With an increase in room temperature, the thermostat output pressure is increased and the actuator opens to increase primary
cooling airflow to the space. With a decrease in room temperature, the opposite action occurs.
