EKC 102
Application
• The controller is used for temperature control refrigeration appli-
ances and cold room
• Defrost control
• For front panel mounting
Advantages
• Integrated refrigeration-technical functions
• Defrost on demand in 1:1 systems
• Buttons and seal imbedded in the front
• IP 65 enclosure 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)
Control
The controller contains a temperature control where the signal
can be received from one temperature sensor.
The sensor is placed in the cold air ow after the evaporator or in
the warm air ow just before the evaporator.
The controller controls the defrost with either natural defrost or
electric defrost. Renewed cutin after defrost can be accomplished
based on time or temperature.
A measurement of the defrost temperature can be obtained
directly through the use of an S5 sensor.
One, two or three relays will cut the required functions in and out
– the application determines which:
• Refrigeration (compressor or solenoid valve)
• Defrost
• Alarm
• Refrigeration 2 (compressor 2)
• Fan
The dierent applications are described on next page.
The series
There are four controllers in the series:
A-model for simple regulation
B-model where an alarm function and possibly also a digital input
will be required
C-model where the defrost temperature also enjoys top priority
D-model with fan function, change-over between temperature
reference and case cleaning function
All these four controllers are without data communication.
If data communication or additional functions are required, we
refer you to the EKC 202 or AK-CC 210 series.
