Dual Duct, Minimum Air From Cold Duct
NOTE: Connect jumper from T2 to R1 (shown) to
override cooling minimum to zero, upon
call for heating. Connect R2 to ground (–).

Dual duct applications can use two CSP-5001 series
controllers with a dual-setpoint (RA/DA) thermostat,
as shown below. In this application the CSP-5001
controllers are mounted separately on the cold and
hot air duct dampers with each utilizing it’s own
ow sensor.
The cold-deck controller receives the “T1” signal
from the thermostat while the hot-deck controller
receives its requested ow signal from “T2.” Both
units can be set independently for minimum and
maximum ow seings. In addition, by using the
“R1” or “R2” override terminal on the thermostat,
minimum ow can be overridden to zero upon a call
for heating (or vise-versa).
