EKC202B, EKC302B CONTROLLER SETTINGS ADJUSTMENT
1.
PURPOSE
The controller as part of the refrigeration equipment is designed to control its operation and provides the
following:

maintaining the temperature in the refrigerated space within the required range;

automatic defrost of the air cooler;

compressor protection.
The front panel of the controller is shown in Fig. 1.

7 defrosting indicator (illuminated); 8 - refrigeration indicator (illuminated).

BRIEF DESCRIPTION
The front panel of the controller contains three programming keys (1), (2), (3) and a display that shows three
numbers or letters (4), a minus sign (5), an air cooler fan activation signal (6), a defrosting signal (7), and a
refrigeration signal (8).
The controller maintains the interior temperature by periodical starting and stopping the compressor according
to a signal received from the sensor installed in the air cooler. If the interior temperature exceeds the set value
(the first line in Table 1), then the controller activates the compressor. After reaching the specified interior
temperature, the controller stops the compressor. When the compressor is disabled, the interior temperature
increases due to heat flows, and when a value equal to the sum of the previous set value (the first line in Table
1) and the value "r01" is reached, the controller activates the com-pressor.
When products are cooled (the compressor is running), the display (4) shows the interior temperature value and
the refrigeration signal (8). When the compressor is disabled, the refrigeration signal (8) is not displayed.
To see the temperature on S5 evaporator sensor, press briefly the key (2), and to activate the forced defrosting,
press and hold the key (2) for 5 seconds.
