Dual Duct, Minimum Air From Cold Duct - KMC Controls CTE-5202 Application Manual

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 flow sensor.
The cold-deck controller receives the AO1 signal
from the thermostat while the hot-deck controller
