button – holding for more than 5 seconds activates one of preprogrammed compressor special modes
( parameter). Quick press returns to normal mode. button highlighting specifies compressor state: no
highlighting – compressor off; highlighting – compressor is on. Special mode is signaled by flashing button.
In change setting mode ( button highlighted) pressing the button increases the temperature. In parameter
modification mode pressing the button displays consecutive parameter symbol or increases the value. In input
service code mode pressing the button increases the code number.
button - holding for more than 5 seconds activates manual defrosting signaled by flashing. Automatic
defrosting is signaled by continuous highlighting. In change setting mode ( button highlighted) pressing the
button decreases the temperature. In parameter modification mode pressing the button displays preceding
parameter symbol or decreases the value In input service code mode pressing the button decreases the code
number.
button - holding for more than 1 second activates change setting mode signaled by highlighting
button. In parameter modification mode pressing the button switches between parameter symbol and its
value. In input service code mode pressing the button confirms the code. Holding and buttons for
more than 5 seconds activates all available parameters modification mode (preceded by inputting correct
service code)
button - holding for more than 5 seconds activates selected parameter modification mode (parameters not
requiring service code). In case of , = 2 parameter, quick button pressing switches on and off relay AUX (e.g.
lighting). In parameter modification mode holding the button for more than 1second saves modified
parameters and returns to normal mode. Holding the button while switching on till message displays,
returns to parameter default settings.

5. LED display (3 - digit ) SdL- In standard mode it displays detector temperature determined by the parameter
(0 – thermostat probe, 1 – defrost probe). Displayed temperature range: between - 40 C and + 40 C.
Temperature below -10 C is displayed with resolution of 1 C, and temperature above -9.9 C with resolution of
0.1 C. In change settings mode (SET button highlighted) the set temperature is displayed. In programming mode –
parameter editing - parameter symbol or value is displayed. Alarm codes and service code being input are also
displayed (in service code input verification).

To display or modify settings:
1) Press and hold for more than 1 second. The temperature setting is displayed and the button is highlighted.
2) Set the temperature using and .
3) Confirm by pressing again. Highlighting button is off. Current temperature is displayed.
If button is not pressed for 30 seconds, previous settings are restored.
It is possible to initiate defrosting manually. The necessary condition is that defrost probe temperature is below
( (final defrosting temperature) -1 ). To initiate defrosting process press and hold for more than 5
seconds. Manual process initiation is signaled by flashing button. When theprocess is initiated automatically
the button is highlighted continuously.
Press and hold for more than 5 seconds, the screen displays the code of the first commonly available parameter.
1) Press and hold and for more than 5 seconds, the screen displays “0”.
2) Press or to display “33” (password granting access to all configuration parameters). button
returns to normal running mode.
3) confirms the password. Confirming incorrect password displays “0”.
4) Correct password – code of the first modified parameter is displayed.
After displaying code of the first parameter:
1) Press or to display the number of a parameter to modify.
2) Press to display parameter value.
3) Press or to increase or decrease parameter value.
4) Press to initially save new parameter value and return to parameter code display.
5) To modify other parameters, repeat steps 1 to 4.
To save modified values, press and hold for more than 1 second and the programming procedure is
terminated.

Special running modes – “COMP” (to enter special mode, press and hold COMP for
more than 5 seconds; to leave special mode, quickly press COMP)
0 - no “COMP’’ button control
1 - always off - signaled by short flashes of COMP button
2 - always on - signaled by long flashes of COMP button
3 - always on with temperature limit – Cst parameter
Compressor is turned off when it reaches the temperature specified by Cst
parameter, and turned on when temperature rises to Cst + AHS
Modes 2 and 3 – active limits: min. compressor standstill time and

To enter special mode, press and hold for more than 5 seconds.
“Compressor - always off” mode ( =1) is signaled by short flashes of button.
“Compressor - always on” modes ( =2 or 3) signaled by longer flashes of button.
1) Holding while initiating the regulator (during dot flashing) restores default settings; signaled by
displaying for 2.5 seconds.
2) Holding while initiating the regulator (during dot flashing) enters service mode. In service mode
compressor control time limits are eliminated; useful when testing and initiating cooling unit.
- displayed during initialization of regulator with default settings
- signals read/write EEPROM data error
- thermostat probe malfunction
- defrost probe malfunction
- high temperature alert (displayed In rotation with detector temperature specified by SdL parametr)
- low temperature alert (displayed In rotation with detector temperature specified by SdL parametr)

Defrosting mode
0 - defrosting heater – termination based on the temperature or when time limit
is exceeded
1 - "hot gas" (compressor is on) -termination based on the temperature or
when time limit is exceeded
2 - defrosting heater - termination after time limit is exceeded
3 - hot gas - termination after time limit is exceeded
4 - defrosting off
Detector not required in modes 2, 3 and4-no“nodetector” alarms.
Defrosting parameters

Fan controls
0 – fan is on, no defrosting
1 – fan is on depending on the evaporator detector temperature
Setting – fan switching on
fan on if: evaporator temp.< fan setting – alarm hist. (FSt - AHS)
fan off: evaporator temp. > fan setting (FSt)
Fan switching off if compressor is on.
0 – no switching off
1 – switching off
Low temp. alarm – deviation from setting
ALo=0-alarm off
High temp. alarm – deviation from setting
