Installation Guide
Mounting
CSC-3000 series controllers are position sensitive and must
be mounted and calibrated in either the horizontal or
vertical plane.
1. As near to the ow sensor pickup as is feasible,
connect the mounting bracket to the mounting surface
with two self-threading screws in the two 3/16" (5 mm)
mounting holes. Be sure to leave enough room to make
connections.
2. Insert the controller, face down, up, right or le. The
controller must be installed and adjusted in the same
plane or readjustment will be necessary.
Connections
All dimensions are in inches (mm)
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.
*(These instructions do not apply to the CSC-3014 or the
CSC-3501/3505; see their separate Installation Guides.)

Typical CSC-3011 Application and Connections
For all models of the CSC-3000 series, use 1/4" (5 mm)
O.D. “FR” tubing on the following push-on ings:
1. Connect the clean, dry, oil-free main air supply to Port
“M” (15 to 30 psi).
2. Connect the damper actuator to Port “B”.
3. Connect the thermostat output to Port “T”.
4. Connect the high pressure tap on the air ow sensor to
Port “H”.
5. Connect the low pressure tap on the air ow sensor to
Port “L”.
6. Check for proper connections. Make sure all tubes
are snug on their ings. If loose, trim the end of the
tubing and reconnect it to ensure there are no leaks.
NOTE: Over time, the tube may stretch or develop
microcracks. Trim the end of tube back to
undamaged material and reconnect. Replace the
tubing if it is brile or discolored.
NOTE: You can easily test for leaks with a squeeze
bulb to ensure there are no leaks at the actuator
diaphragm or ings.
7. Use a ow hood or “tee” a Magnehelic® (or equivalent)
dierential pressure gauge between the controller and
the ∆P pick-up to determine ow rates.

CSC-3000 Series 2 Installation Guide
NOTE: The reverse reset illustration above assumes no
relays between the thermostat and “T” port.
For Reverse Reset (RA thermostat for cooling or DA
thermostat for heating), perform the following steps:
1. Disconnect the “T” port and leave it open. Temporarily
plug the open tubing.
2. Adjust the LO STAT ∆P (center dial) to the desired
Maximum airow.
3. Reconnect the tubing at port “T”.
4. Adjust the thermostat to call for minimum airow (15
psi or more at “T” port).
5. Adjust the HI STAT ∆P (dial on the right) to the
desired Minimum airow.
6. Repeat Steps 1 through 5 to verify the seings.
DIRECT Reset Minimum and Maximum
NOTE: The direct reset illustration above assumes no
relays between the thermostat and “T” port.
For Direct Reset (DA thermostat for cooling or RA
thermostat for heating), perform the following steps:
1. Disconnect the “T” port. Temporarily plug the tubing.
(Do NOT plug the port.)
2. Adjust the LO STAT ∆P (center dial) to the desired
Minimum airow.
3. Reconnect the tubing at “T” port.
4. Adjust thermostat to call for full airow (15 psi or
more at “T” port).
5. Adjust the HI STAT ∆P (dial on right) to the desired
Maximum airow.
6. Repeat Steps 1 through 5 to verify the seings.

ments, calibration, troubleshooting,
principles of operation, and sample ap-
plications, see the Application Guide for
these controllers. For support documents,

REVERSE Reset Minimum and Maximum
Adjustments and Calibration
NOTE: Do NOT adjust start point and span (upper and
lower knobs) without thoroughly reviewing the
Application Guide. For information about direct
vs. reverse reset, see the Application Guide.
Damper Action
The damper action is factory-set at Normally Open (NO).
To change to Normally Closed (NC):
1. Loosen the damper selection screw.
2. Turn the selection dial clockwise until the “NC” arrow
aligns with the “DAMPER” arrow.
NOTE: Accuracy in the alignment of the arrows is
very important. Make this adjustment as exact
as possible.
3. Tighten the selection screw. Be sure the screw is tight
(2 to 4 in-lbs. of torque), but if overtightened, the
plastic will strip out.
Adjusting Minimums and Maximums
When adjusting the minimum and maximum ow
seings, the output responds slowly to changes in the
setpoint. Wait for the ow rate to stabilize aer making
an adjustment (usually 20 to 30 seconds) before making
further adjustments. Also, if the damper position is all
the way closed or open when starting this step, turn the
adjustment one full turn, and then wait 20 to 30 seconds
for a change in the ow reading of the Magnehelic gauge.
If no change occurs aer this time, repeat until the ow
rate changes. (See the Application Guide for more tips.)
