Pressure Independent VAV Applications with CSP-4702 20 CTE-5202 Applications Guide, AN0912A Rev. H
Replacing a CSP-5001/5002
The CSP-4702 can be used in any of the CSP-
5001/5002 applications shown in the section Pressure
Independent VAV Applications with CSP-5001/5002
on page 32. However, there are some dierences
among the models of which the installer must be
aware:
• Output torque of the CSP-4702 is 40 in. lb.
instead of the CSP-500x’s 50 in. lb. Check torque
requirements of the damper when replacing a
CSP-500x.
• Factory-set rotation direction of the CSP-4702
is CCW to close and CW to open, the same as
the CSP-5001. The direction can be reversed by
changing the position of a jumper.
• If a CSP-4702 is used to replace an existing
CSP-500x and limits were set in the CSP-500x,
the limits will need to be set (in either the CSP-
4702 or the thermostat). If a CSP-4702 is used to
replace an existing CSP-500x and limits were set
in the thermostat, the limits in the thermostat
should be checked and adjusted to ensure ac-
curacy.
• The terminals on the CSP-4702 terminal strips
are in a dierent order than on a CSP-500x.
• “Override to Fully Closed” shown in Auto and
Override (to Fully Closed or Fully Open) on page
34 will not work as described with the CSP-4702.
See the Operation Test section of the CSP-4702
Installation Guide.
NOTE: Compare the wiring of the CSP-4702
version of cooling with heating changeover
below to the CSP-5001 version in Cooling
with Heating Changeover on page 37. See
also Cooling with Heating Changeover on
page 26.
