Pressure Independent VAV Applications with CSP-4702 23 CTE-5202 Applications Guide, AN0912A Rev. H
Auto and Override (to Fully Open)
Adding a SPDT relay or switch enables overriding
the air ow to fully open. (Otherwise the example
below is the same as the cooling conguration in
Cooling or Heating on page 22.)
The SPDT relay selects one of the two modes (Auto/
Open). In the relay position shown below (Open),
the controller will override the ow seing. (Jump-
ing “2-10 IN” and “16 VDC OUT” drives the CSP-
4702 fully open.)
NOTE: If a maximum limit was set in the CSP-4702
controller, the damper will only open to
the maximum limit seing. See also the
Operation Test section of the CSP-4702
Installation Guide.
When the relay switches to Auto, the thermostat will
then control the VAV box based on demand.
