Technical brochure Temperature controller

type EKC 100

Introduction The controller is used for temperature control of refrigeration plant.

Operation, setting and programming are optimised and simplified as much as possible.

The controller is designed so that temperature control and defrost control can be made via pump down or start/stop of the compressor.

Set temperature1. Push the middle button until the temperature value

is shown2. Push the upper or the lower button and select the

new value3. Push the middle button to select the setting.

Manual start or stop of a defrost• Push the lower button for five seconds.

Set menu1. Push the upper button until a parameter is shown2. Push the upper or the lower button and find that

parameter you want to change3. Push the middle button until the parameter value

is shown4. Push the upper or the lower button and select the

new value5. Push the middle button again to enter the value. Time out 20 sec.

Warning ! Direct start of compressors *To prevent compressor breakdown parameter c1 and c2 should be set according to suppliers requirements or in general :Hermetic Compressors c2 min. 5 minutesSemihermetic Compressors c2 min. 8 minutes and c1 min. 2 to 5 minutes ( Motor from 5 to 15 KW )* ) Direct activating of solenoid valves does not require settings different from factory (0)
