Descriptions and Applications
The analog electronic CEP-4000 series is a pressure-
independent combination controller-actuator de-
signed primarily for use on variable air volume ter-
minal units. Cooling and heating air ow is sensed
by a temperature-compensated hot-wire anemom-
eter. Velocity sensing is unaected by changes in the
duct air temperature.
The CEP-4000 series oers full-range ow control
of VAV terminal units when used with the CTE-
1000/1100/5000 series as well as the CTE-5202 room
thermostats. Air-velocity ow control limits are set
at the room thermostat or remotely with the REE-
1012 remote-limits accessory module.
The actuator section provides a magnetic clutch
that allows the actuator to be stalled at either end of
stroke, eliminating the requirement for mechanical
stops or end switches. It is available with (100°and
60°) built-in stops.

*NOTE: (Not all possible model number
congurations may be available. See the
web site.)
**NOTE: The default rotation direction can easily
be reversed by swapping the red and blue
motor wires.
When replacing an older model, 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. If re-
placing 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. See the
CEP-4000 Applications Guide for more information.
