CEP-4000 Series VAV Flow Controller-Actuators 3 Applications Guide
Model History and Replacement Issues
The CEP-4000 series uses a “half-wave” power
circuit, which is not compatible with some of the
REE-1000 series accessories module relays (that
may be found in earlier installations). Therefore,
when replacing a CEP-1000 or CEP-3000 series
controller, the REE-1000 series relay may also need
to be replaced with the equivalent REE-4000 series
module:
With Electric Motor used aer data code 9226.
(Motor Gearbox replacement is HPO-0062.)
With Electric Motor used before data code 9225.
(Motor Gearbox replacement was HPO-0013, but it is
no longer available.)
Determine the controller model number from the
chart below. All units have a predened stroke range
with factory-installed stops (or full 360° rotation with
no stops). Each model is dened by which direction
the damper closes (eld adjustable) and which of
the four sensor options are shipped with the unit.
(Sensors are eld replaceable, but recalibration is
then required.)
The CEP-4995 (100° rotation, CW to close, no sensor)
is a “universal replacement” for most applications
and will replace MOST CEP-1000/3000/4000
series controllers. (See the CEP-4995 Universal
Replacement section on the next page.)
REE-1001 replace with REE-4001
REE-1
002 replace with REE-4002
REE-1
006 replace with REE-4006
REE-1
011 replace with REE-4011
REE-1
015 replace with REE-4015
REE-1
017 replace with REE-4017
REE-1
019 replace with REE-4019
**NOTE:
The default rotation direction can easily
be reversed by swapping the red and blue
motor wires. (See the Rotation Setup and
Override section.)

that may be contaminated with corrosive
materials or high humidity. See also the
data sheet for the SSE-1000/2000 Series.
