CEP-4011 | Controller: VAV, 45 in-lbs, 100 deg, CW Close, SSE-1001 | KMC Controls (OBSOLETE)

The analog electronic CEP-4000 series pressure-independent controller-actuators are designed primarily for use on variable air volume terminal units. Cooling and heating air flow is sensed by a temperature-compensated hot-wire anemometer. Velocity sensing is unaffected by changes in the duct air temperature.

The CEP-4000 series offers full-range flow control of VAV terminal units when used with the CTE-1000/1100/5000 series as well as the CTE-5202 room thermostats. Air-velocity flow 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. The controller-actuator is available with 100° or 60° built-in stops.

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. (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—see the CEP-4000 Applications Guide for more details.)

NOTE: CEP-4xxxC models with silicon conformal coatings have been discontinued.
