EKC 102 - Temperature controller
EKC 102 controllers for panel mounting are used for temperature and defrost
control via pump-down or start/stop of compressor.
Functions
Advantages
Thermostat
• ON/OFF thermostat
• Sensors: Danfoss Pt1000, PTC1000 or NTC5000
• Calibration of sensors
• Day/night control
• Alarm thermostat with delays
• Integrated refrigeration-technical functions
Defrost
• Electrical or natural defrost
• Start via DI input, time interval or display
• Defrost on demand
• Stop on time or temperature
Compressor
• Anti cycle timers for optimum compressor protection
• High-effect 16A relays for connection of compressors
without use of intermediate relay
• Control of 2 compressors (version 102B)
Multipurpose DI input
• Multipurpose DI input for defrost start, day/night control, dooralarm or main switch
Other functions
• The S5 sensor can be used for monitoring of condenser
temperature or as product sensor (version 102B+102D)
• Door function with alarm monitoring
• Manual control of outputs
• Delay of outputs at power up
Display & Programming
• High-efficient LED display with icons for indication of
operational status. Parameter settings/readouts and alarm
conditions can be read on the display.
• ”Copy key” programming key with room for 25 different
controller setups
Fan (102D only)
• Fan delay during defrost
• Fan stop when compressor cuts out
• Fan stop at high S5 temperature
• Defrost on demand in 1:1 systems
• Buttons and seal imbedded in the front
• IP65 density from the front panel
• Can control two compressors
• Digital input for either:
- Door alarm
- Defrost start
- Start/stop of regulation
- Night operation
- Change-over between two temperature reference
- Case cleaning function
• Instant programming via programming key
• HACCP
Factory calibration that will guarantee a better measuring accu­racy than stated in the standard EN 441-13 without subsequent calibration (Pt 1000 ohm sensor)
