Dual Duct, Minimum Air from Cold Duct
Dual duct applications can use two CSP-4702s with
a CTE-5202. In this application, the CSP-4702s are
mounted separately on the cold and hot air duct
dampers with each using its own ow sensor.
The cold-deck controller receives the AO1 signal
from the thermostat while the hot-deck controller
receives its requested ow signal from AO2. Both
CSP-4702s can be set independently for minimum
and maximum ow seings.
Select Sequence 3 (from the CTE-5202 SYSTEM
menu). See Change Conguration on page 6.
