PNEUMATIC CALIBRATION PROCEDURES

CP100 / CP200

General
1. Remove the protective metal cover.
2. Aligned markings on the face and dials of the controller
indicate that the factory settings are intact.
3. Remove the caps from the tees in the HI (red) and LO
(green) tubes leading from the air flow sensor in the
assembly inlet. Connect a differential pressure gauge
to the tees. A gauge with a 0 to 1 inch w.g. scale is
recommended.
4. Refer to the calibration curve for the size assembly being
serviced. From the curve on page 13, read the differential
pressure across the sensor for the required air flow.
5. Alternately, calculate the differential pressure from the
equations on page 13.
CP100 (If Supplied)
1. Adjust the minimum (LO) air flow limit first.
2. Set the thermostat signal to 0 psi, or disconnect the
thermostat tube to the controller.
3. Turn the minimum (LO) dial on the controller (center knob)
until the gauge reads the required differential pressure.
Turn the dial slowly, allowing time for the damper actuator
to complete its travel in response to the adjustments.
(Verify the minimum set point by cycling the thermostat
pressures).
4. Apply 15 psi minimum air pressure to the thermostat
connection at the controller.
5. Turn the maximum (HI) dial on the controller (outer knob)
until the gauge reads the required differential pressure.
Turn the dial slowly, allowing time for the damper actuator
to complete its travel in response to the adjustments.
(Verify the maximum set point by cycling the thermostat
pressure).
