Dual Duct Heating And Cooling Vav - KMC Controls CTE-5202 Application Manual

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
flow sensor.
The hot deck controller receives its requested flow
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 flow
settings.
Sequence 3 should be selected from the CTE-5202
SYSTEM menu. See Change Configuration on page
(See also the (Dual Duct) Heating and Cooling VAV
section with a CTE-1103 in the
Applications Guide.)
