Pressure Independent VAV Applications with CSP-4702

Replacing a CSP-5001/5002
The CSP-4702 can be used in any of the CSP-
5001/5002 applications shown in the section
Independent VAV Applications with CSP-5001/5002
.
However, there are some differences
among the models of which the installer must be
aware:
•
Output torque of the CSP-4702 is
4
0 in. lb.
instead of the CSP-500x’s
5
0 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-500
1
. 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 different order than on a CSP-500x.
•
“Override to Fully Closed” shown in
Override (to Fully Closed or Fully Open) on page
will not work as described with the CSP-4702.
