Pressure Independent VAV
Applications with CSP-5001/5002
This section gives sample applications for using the
CTE-5202 as a substitute for the CTE-5100 series
thermostats with the CSP-5001/5002 VAV controller-
actuator. (For replacement of the CSP-500x by the
CSP-4702, see Replacing a CSP-5001/5002 on page
20.)
Factory-set rotation direction of the CSP-5001 is
CCW to close (CW to open or CW with increasing
voltage), and the CSP-5002’s is CW to close (CCW to
open or CCW with increasing voltage). The direc-
tion can be reversed by changing the position of a
jumper. The CSP-5001 (with default direction) is
used in the examples of this section.
See also the CSP-5001/5002 Applications Guide.
Concerning replacements of the CTE-510x thermo-
stats, see Cross-References on page 8.
To manually open the box, remove wiring from
Terminal IN and jumper Terminal IN to Terminal 16
VDC. This will tell unit to control at 3300 fpm (full
airow), the green LED should turn on, and the box
should drive open).
To manually close the
box, remove wiring
from Terminal IN, and
jumper Terminal IN to
Terminal –. This will
tell unit to control at
zero fpm (no airow),
the red LED should be
on and the box should
drive closed.

3/8" to 1/4" Union Adapters
1/4-Inch Tubing
3/8" Tubing
NOTE: If using an SSS-101x sensor (instead of an
SSS-100x), the 3/8" tubing and adapters
shown in the illustration are unnecessary.
NOTE: See also Auto and Override (to Fully Closed
or Fully Open) on page 34. Full rotation
may take ve to six minutes because the
actuator rotates at 18° per minute.
