CEP-4703 | Controller, LAT ; 40 in-lb

The compact, analog electronic CEP-4703/CEP-4703V is a combination controller-actuator designed to control the DAT (Discharge Air Temperature, also known as LAT or Leaving Air Temperature) primarily in fan coil and unit ventilator applications. It can be configured for heating or cooling applications.

DAT temperature setpoint is determined by a resistor (purchased separately) connected to the terminal block. DAT temperature is measured by a remote STE-1401 (or other 10K Type III thermistor sensor). A sensitivity adjustment (potentiometer) determines the speed of response to measured temperature changes away from setpoint.

The CEP-4703V has a bracket with a patent-pending, quick-mounting mechanism for attaching to valves.

The CEP-4703 mounts directly to 1/4- to 5/8-inch (6 to 16 mm) round shafts or 1/4- to 7/16-inch (6 to 11 mm) square shafts, eliminating the need for expensive and complicated linkages. (An HLO-4001 crank arm kit is available, however, for when direct mounting is impractical.) An HMO-4002 non-rotation bracket, to prevent lateral movement, is included. (An HMO-4001 non-rotation “T” bracket is also available for spanning open distances.)

A gear disengagement button allows easy manual positioning of the actuator.
