Pressure Independent VAV Applications with CEP/CSP-4000 Series 52 CTE-5202 Applications Guide, AN0912A Rev. H
Dual Duct Heating and Cooling VAV
Dual duct applications connect two CEP-4000 series
controllers, mounted separately on the hot and cold
air-duct dampers, with each controller using its own
ow sensor.
The hot deck controller receives its requested ow
signal from AO2 on the CTE-5202, while the cold
deck uses the AO1 signal. Both controllers can be
set independently for minimum and maximum ow
seings.
Sequence 3 should be selected from the CTE-5202
SYSTEM menu. See Change Conguration on page 6.
(See also the (Dual Duct) Heating and Cooling VAV
section with a CTE-1103 in the CEP-4000 Series
Applications Guide.)
