CCC-1001/1002
The CCC-1001 and CCC-1002 are not position sensitive, but they must be calibrated and mounted in the
same orientation.
1. Locate the three mounting ears (anges) on the
unit.
2. Place the controller on the mounting surface and
mark the locations of the two top ears.
3. Partially install two mounting screws (#8 or #10)
on the marks. These should be 3-1/2" (89 mm)
apart.
4. Slide the top ears under the screws.
5. Install the third mounting screw in the boom ear
and tighten all three screws.
The units are supplied as Direct Acting (DA). If
Reverse Acting (RA) is required:
1. Locate the tubing connections on the back of the
controller.
2. Cut the branch tubing at the DA connection
(lower right corner).
3. Remove tubing from the two-prong guides.
4. Connect branch tubing to the RA connection
(upper right corner) using brass ings
(provided).
5. Secure extra tubing in the two-prong guides.
A CCC-1001/1002 controller has ve 3/16" (5 mm)
ports to accept 1/4" (6 mm) O.D. polyethylene tubing.
Connect the controller to other units as follows:
1. Main control air to Port M. This should be 20 psig
(137 kPa), 30 psig (207 kPa) max.
2. Primary input, 3–15 psig, to Port 1.
3. Remote setpoint adjustment, 3–15 psig with a +/–
10% oset, to Port 2.
4. Secondary input to Port 3.
CAUTION
Pneumatic devices must be supplied with clean, dry
control air. Any other medium (e.g., oil or moisture

Adjustments and Calibration
CCC-1001 Controller
NOTE: Throling range is the percent change of
the primary input (Port 1) that causes a
100% change in the branch output (Port B).
Authority is the change in the secondary
input (Port 3) in relation to the change in
the primary input that will cause the same
change in the output and is expressed as a
percentage (see the Authority Calibration
section).
1. Remove cover before making any adjustments.
2. Set the desired throling range:
A. Loosen large center screw (1 turn
maximum).
B. Remove main control air from Port M.
C. Move the setpoint indicator to the desired
% throling range (4 to 40%) on the DA
or RA scale. See the Throling Range
Adjustment section on page 3.
D. Connect main air to “M.”
3. Set the desired authority:
A. Calculate the required authority. See the
Authority Calibration section.
B. Set the authority indicator to the desired
value.
C. Tighten center screw.
4. Adjust the setpoint output by turning the setpoint
screw (located at the lower right of the unit). See
the Setpoint Calibration section on page 3.
5. Reinstall the cover.

NOTE: Follow the steps 1 through 4 for adjusting
the CCC-1001, and then continue with steps
5 through 8.
Throttling Range Adjustment
Throling range % can be calculated by the following formula:
Port 1 Units Desired to Make
100% Change in Port B (Output)
Port 1 Primary Input Span
(Same Units as Above)
x
Span of Controlled
12
x 100
Device (psi)
Example: Port 1 is connected to a temperature
transmier with a range of 40 to 240° F
(200° F span). Branch output is controlling
a 3 to 8 psi (5 psi span) device. Desired
throling range is 20° F. Then throling
range % = (20° F)/(200° F) x (12 psi)/(5 psi) x
100 = 24%.
Authority Calibration
This adjustment determines the eect of a secondary
transmier (Port 3) on the setpoint of the receivercontroller.
Example: Reset the HWS (Hot Water Supply)
temperature setpoint based on OAT
(Outside Air Temperature). The HWS
transmier has a range of 40 to 240° F for 3
to 15 psi (0.06 psi/° F), and it is connected
to the Port 1 primary input. The OAT
transmier has a range of –40 to 160° F for 3
to 15 psi (0.06 psi/° F), and it is connected to
the Port 3 secondary input.
NOTE: This example does not compensate for TR
(throling range) across the reset schedule
but assumes a constant branch pressure.
The reset schedule shows the temperatures and pressures at the extreme ends of the operating schedule.
5. Turn the face dial until the desired input signal
(Port 1) pressure value lines up with the clear
arrow indicator.
6. Carefully slide the cover straight down, so that
the cover gear teeth and the setpoint adjustment
sha mesh.
7. Tighten the cover.
8. Apply the adhesive dial face if required.
