6 OPERATION MODES
6.1 MCK-102-14 has 3 modes of operation: thermostat mode; defrost mode and the mode to control and
set the required parameters.
6.2 THERMOSTAT MODE
6.2.1 In thermostat mode of operation MCK-102-14 maintains necessary user-specified temperature
inside the refrigeration chamber by operating the compressor. Please see below the scheme showing how
MCK-102-14 relay output contacts operate by compressor depending on time and temperature inside the
refrigeration chamber (scheme is shown for the default factory settings).
MCK-102-14 relay output contacts operate by compressor depending on time and temperature inside the
refrigeration chamber (scheme is shown for the default factory settings).
6.2.2 Compressor operation. Parameters SP (setting point) and dif (differential) determine the
temperature conditions in refrigerated chamber. If temperature value becomes higher then SP+dif then the
compressor will turn ON and will keep working until the temperature reaches the value of SP parameter.
compressor will turn ON and will keep working until the temperature reaches the value of SP parameter.
In case of malfunction or failure of the temperature sensors MCK-102-11 operates with the compressor in
alarm mode using parameters COn and COF which determine the time intervals for ON/OFF state of the
compressor. This alarm situation is indicated by alarm codes Er2 or Er3 shown on display.

6.3 DEFROST MODE
To perform the defrost of the refrigerated chamber MCK-102-14 turns OFF the compressor for the user
To perform the defrost of the refrigerated chamber MCK-102-14 turns OFF the compressor for the user

6.4 FIRST START UP FEATURES
When power supply is given to the input terminals of the MCK-102-14 on the display it is shown
within first 5 seconds. Then further MCK-102-14 operation algorithm will depend on the value of and
parameters.
parameters.
If
=1 tttt:
- if =0 then after time defined by parameter +30 seconds MCK-102-14 will switch to thermostat
mode;
- if =1 then after time defined by parameter +30 seconds MCK-102-14 will switch to defrost
mode.
The first switching ON compressor will happen not early than time of autoreclosing (parameter
) or
time of no load trip of compressor (parameter
) depending on whether which time is more.
If
=0 autoreclosing time delay is equal 0.
