Danfoss Electronic Controller Controller (type EKC 201 EKC 301)

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.
