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 airow
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 Conguration on page 6. (This
replaces a CTE-1001/1101/5001/5011 with Direct
Acting reset.)
