Any sequencing with other controllers, valves, or
pneumatic-electric relays must be sequenced with
the controller’s reset range, not the actuator’s spring
range.
These controllers are typically used on single-duct
applications but may be found in dual-duct appli-
cations. When working on dual-duct applications
it may be necessary to work on one duct at a time
while closing off the other.
The CSC-2000 series controllers are position sensi-
tive. See the Mounting section on the next page for
the proper vertical/horizontal orientation for the dif-
ferent models.
CAUTION
Pneumatic devices must be supplied with clean,
dry control air. Any other medium (e.g., oil or
moisture contamination) will cause the device
to fail.
CSC-2000 Series Overview
The CSC-2000s are differential-pressure (∆P), sub-
master controllers with adjustable minimum and
maximum airflow settings. A master controller,
typically a room thermostat, resets the CSC velocity
setpoint.
CSC-2000s are available as direct acting for normally
open VAV terminal units, and reverse acting for nor-
mal closed VAV terminal units. Each unit is equipped
with separate adjustment knobs for minimum and
maximum airflow settings. CSC-2001/2002s are
equipped with 0–10 reference dials, while all others
have blind adjustments. Calibrate all models using
standard airflow measuring equipment.
The spring range of the actuator does not matter
to the controller. However, sufficient main air is
required to provide the actuator with enough force
to operate the damper/linkage.
