KMC Controls CTE-5202 Application Guide

Pressure Independent VAV Applications with CEP/CSP-4000 Series 51 CTE-5202 Applications Guide, AN0912A Rev. D
Damper Tracking (Master/Slave)
The conguration is used for special applications
where a dierential pressure is needed (either posi-
tive or negative). The thermostat controls the “mas-
ter” CEP-4xxx controller-actuator and an REE-1013
relay controls the “slave.” The relay takes the voltage
reading from the master CEP-4xxx and repeats it to
the slave CEP-4xxx plus or minus a given oset.
As an example, the master CEP-4xxx 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 “oset”
would be 0.10 VDC to set-up the REE-1013. See the
Voltage/Velocity Correlation section in the CEP-4000
Series Applications Guide. With the REE-1013, the
maximum oset is ±2 VDC as measured by a voltme-
ter between the + and – terminals.)
