Outdoor Air Content Sensor
The purpose of the DCV sensor is different
from that of the outdoor air content sensor. On
the economizer modules equipped with
outdoor air content sensors the purpose of the
sensor is to keep the outside air dampers at a
minimum position if the outdoor air is above its
setpoint threshold. Alarm contacts on the
economizer module will close if both the
outdoor and indoor air (DCV) signals are
above their respective setpoint thresholds.
