Cooling - KMC Controls CTE-5202 Application Manual

Cooling

CTE-5202 thermostats can use CEP/CSP-4000 series
electronic VAV controllers to operate damper boxes
in a pressure-independent VAV system. As shown
in the diagram, a "requested flow" voltage signal
(AO1) is connected to the CEP-4xxx to adjust airflow
from minimum to maximum flow according to
space demand. Minimum and maximum flow limit
adjustments can be made at the thermostat or at the
controller.
