CTE-5202 thermostats can use CEP/CSP-4000 series
electronic VAV controllers to operate damper boxes
in a pressure-independent VAV system. As shown
in the diagram, a “requested ow” voltage signal
(AO1) is connected to the CEP-4xxx to adjust airow
from minimum to maximum ow according to
space demand. Minimum and maximum ow limit
adjustments can be made at the thermostat or at the
controller.
Select Sequence 1 (from the CTE-5202 SYSTEM
menu). See Change Conguration on page 6. (This
replaces a CTE-1001/1101/5001/5011 with Direct
Acting reset.)
(See also the Cooling section in the CEP-4000 Series
Applications Guide.)
