CSP-5001/5002 VAV Flow Controller-Actuators 2 Applications Guide, Rev. B
General Information
CSP-5001/5002 Overview
The analog electronic CSP-5001/5002 VAV ow
controller-actuators are pressure-independent
combination controller-actuators designed primarily
for use on variable air volume terminal units. Air
ow is sensed by using a single or multi-point
dierential (velocity) pressure measuring station
or pitot tube. Designed with an onboard ow-
through sensor utilizing twin platinum resistance
temperature detectors, these models are capable of
controlling a velocity setpoint from 0 to 3,300 fpm
with an accuracy of 3%.
The CSP-5001/5002 oers full range ow control of
VAV terminal units when used with the CTE-5100
series room thermostats. Air velocity ow control
limits may be set at the thermostat or internal to the
CSP-5001/5002. The actuator section provides adjust-
able stops, magnetic clutch and a gear disengage-
ment buon.
On older models, a tri-color LED indicates green for
opening, red for closing and white/o for satised
damper positions. On newer models, two separate
red and green LEDs indicate opening and closing.
Two models are available:
CSP-5001: CCW to close
CSP-5002: CW to close
Available control options include proportional or
two position wet or electric reheat, dual minimums,
fan induction, dual duct, and 0–5 VDC output to a
building automation system interface.
For more information, see the Data Sheet and the
Installation Guide for the CSP-5001/5002.
NOTE: For use with the CTE-5202 thermostat
instead of the CTE-5100 series, see the
CTE-5202 Applications Guide.
