EKC 202 - Refrigeration controller
The series of EKC 202 controllers can be used for a wide range of different
refrigeration applications – from control of air temperatures and defrost to more
advanced applications, including control of light and fans.
Functions
Advantages
Thermostat
• ON/OFF heating or cooling thermostat
• Sensors: Danfoss Pt1000, PTC1000 or NTC5000
• Day / night control
• Thermostat band
• Alarm thermostat with delay
• Integrated refrigeration-technical functions
Defrost
• Electrical, natural or hot gas defrost
• Start via DI input, time interval or schedule (RTC)
• Defrost on demand
• Stop on time or temperature
• Coordinated defrost
Compressor
• Anti cycle timers for optimum protection
• High-effect 16A relays for connection of compressors without
use of intermediate relays
DI input
• Multi purpose DI input for defrost start, door function, night
setback, main switch, appliance cleaning, general alarm,
defrost coordination and thermostat band.
Fan
• Fan delay during defrost
• Fan stop when compressor cuts out
• Fan stop at high S5 temperature
Light control
• Light control of day/night, door, or via network
• Defrost on demand in 1:1 systems
• Buttons and seal imbedded in the front
• IP65 density from the front panel
• Digital input for either:
- Door contact function with 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)
