HVAC Refrigeration Temperature Controller EKC EKA Series

HVAC Refrigeration Temperature Controller EKC Series

The controller contains a temperature control where the signal can be received from one temperature sensor.

The sensor is placed in the cold air flow after the evaporator or in the warm air flow 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)

Application:

• The controller is used for temperature control refrigeration appliances 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
• IP65 density from the front panel
• Can control two compressors
• Digital input for either:

- Defrost start

- Start/stop of regulation

- Night operation

- Change-over between two temperature reference

- Case cleaning function

• Instant programming via programming key
• HACCPFactory calibration that will guarantee a better measuring accuracy than stated in the standard EN 441-13 without subsequent calibration (Pt 1000 ohm sensor)

EKC 201 (for panel mounting) and EKC 301 (for DIN-rail mounting) have been specially developed for control duties in refrigeration plant so that operation, setting and programming are optimised 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.

EKC 201 and 301 are used for:
Temperature control/Compressor control
Fan motor control/Defrost control/Alarm signalling

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.

Fitting the EKC controller with a plug-in module for communication gives access to all parameters of the controller. Thus, EKC 201/301 can be included in the ADAP-KOOL® Refrigeration control systems.

The digital input can be programmed to

- receive alarm signals from an external signal source (door alarm)
- start defrost from an external clock
- transmit random alarm signals to the bus system.

Features
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.
Pt 1000 sensors are supplied 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 system.

Real time clock (battery driven) can be fitted.
