EKC 102
EKC 102A
Controller with one relay output and one temperature sensor.
Temperature control at start/stop of compressor.
Natural defrost at stop of compressor.
Instead of the compressor a solenoid valve may of course be
connected in the liquid line.
EKC 102B
Controller with two relay outputs, extra temperature sensor and
digital input.
Relay output 2 can be used for alarm function or for cutin and
cutout of a refrigeration step 2.
The extra temperature signal can be used for product sensor or for
condenser sensor with alarm function.
The digital input can be used for door alarm, defrost start, start/
stop of refrigeration or for night signal.
EKC 102C
Controller with two relay outputs, extra temperature sensor and
digital input.
Relay output 2 can be used for electric defrost or for an alarm
function.
Temperature signal 2 can be used for defrost stop based on
temperature or for product sensor.
In a 1:1 sysem and with the sensor mounted on the evaporator
the controller will be able to use the ”defrost on demand”
function. The function will start a defrost when the evaporator’s
refrigeration capacity drops due to icing-up.
The digital input can be used for door alarm, defrost start, start/
stop of refrigeration or for night signal.
Heating function
The controller can also be used as a simple on/o thermostat for
heating applications.
EKC 102D
Controller with three relay outputs, two temperature sensors and
digital input.
Temperature control at start/stop of compressor/solenoid valve
Defrost sensor
Electrical defrost /gas defrost
Relay output 3 is used for control of fan.
