Standby; Defrosting; Cooling Mode; Anti-Icing Mode - Unicum FOODBOX User Manual

ТМ
The refrigeration unit turns ON or OFF in each of the operational modes. it also includes turning ON or
OFF of evaporator fan and regulation of temperature sensors.
When the Machine is turned ON the refrigeration unit switches to standby mode for two minutes, further
working according to the algorithm of the set mode.
If at the time of turning ON of the Machine the evaporator's temperature (sensor №3) is below the
minimum temperature setting, the regulator switches the Machine into DEfRoStING mode. When the
temperature for Sensor 3 reaches minimum or above minimum value the refrigeration unit is switched to
StANDbY mode.

1.4.5.2 Standby

in the Standby mode the refrigeration unit is in fact turned OFF, the evaporator's fan works as per the
mode set by the user and the sensor readings are obtained.
if the temperature for sensor 1 exceeds the "Max temperature" settings and the defrosting time is
over – the unit switches to COOLiNG mode.

1.4.5.3 Defrosting

in the defrosting mode the refrigeration unit is turned OFF, the evaporator's fan works in accordance
with the user given temperature settings and the temperature sensor readings are noted.
The length of defrosting time depends on the time of defrosting, which is set in the menu item "De-
frosting time". At the end of the set time interval the refrigeration unit switches to the Standby mode. The
length of Defrosting time also depends on the reading s of Sensor 3 – if the temperature of the evaporator
would be below the minimum temperature settings the unit switches to Defrosting mode, or remains in this
mode, until the evaporator's temperature would not exceed the minimum temperature value.

1.4.5.4 Cooling mode

in the cooling mode the unit is turned ON, the evaporator fan works in accordance with the user settings
and the temperature sensor readings are noted.
The duration of refrigeration unit's working cannot exceed 30 minutes. At the end of the given period the
unit turns OFF and after an additional period of two minutes the Regulator switches to STANDBY mode.
if during the working of the refrigeration unit the temperature of sensor 1 drops below the value set in
"Min. temperature" setting – the refrigeration unit turns OFF and after two minutes switches to STAND-
BY mode.
if the temperature for sensor 3 goes below the value set in "Min. Evaporator temperature" settings –
the refrigeration unit turns OFF and switches to ANTi iCiNG mode

1.4.5.5 Anti-icing mode

The Anti-icing mode helps avoid the icing (freezing) of the refrigeration unit. in the given mode the re-
frigeration unit is turned OFF and the temperature readings of the sensor 3 are noted.
When the "Max. Evaporator temperature" is reached – the Regulator switches to STANDBY mode.
To avoid possible icing, please use the recommended values for temperature settings.
