Danfoss EKC 301 084B7515 digital temperature controller

EKC 301 (for DIN-rail mounting) have been specially developed for control duties in refrigeration plant so that operation, setting and programming are optimized and simplified as much as possible. All controllers are designed for room temperature control via pump down or compressor start/stop and have been grouped into four main applications dependent on the type of defrost and its control. With only two keys, all functions can be set and programmed. The display shows the actual room temperature, but by activating the keys the display changes to the set or the actual temperature of the defrost sensor.

• One electronic controller is able to replace several traditional controllers and defrost clocks.
• Can be supplied for panel as well as DIN-rail mounting.
• Temperatures, times, operating conditions, parameter codes and alarm and fault codes can be read from the display.
• Three LEDs indicate the actual condition of the system:
  • Refrigeration
  • Defrost
  • Fan running
• Easy to re-establish factory setting
• In the event of error function, the actual parameter code can be displayed
• All alarms are indicated by the three LEDs flashing at once
• Danfoss Pt 1000 sensors are used with the controller:
  • Calibration of sensor circuit not necessary
  • Controller-sensor system can be used direct for data logging
• Facility for bus communication with SCADA systems
• Real time clock (battery driven) can be fitted
