CEP-4000 Series VAV Flow Controller-Actuators 19 Applications Guide
Damper Tracking (Master/Slave)
The conguration is used for special applications
where a dierential pressure is needed (either
positive or negative). The CTE-1101 DA thermostat
controls the “master” controller-actuator and an
REE-1013 relay is utilized to control the “slave”
controller. The relay takes the voltage reading from
the master controller and repeats it to the slave
controller plus or minus a given oset.
As an example, the master controller is supplying
a velocity of 450 fpm (4.0 VDC on terminal 6), and
the relay commands the slave controller to exhaust
550 fpm (4.1 VDC). The amount of voltage “oset”
would be 0.10 VDC to set-up the REE-1013. See the
Voltage/Velocity Correlation section.
