Dual Duct, Minimum Air from Cold Duct
Dual duct applications can use two CSP-5001s with
a CTE-5202. In this application, the CSP-5001s 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-5001s can be set independently for minimum
and maximum ow seings.
