The measurement of the internal refrigerator temperature is carried out by means of 2 sensors placed inside the refrigerator. The
●
temperature indicated comes from the average value of the two temperatures measured. To prevent the air temperature being mea-
sured in this case instead of the temperature of the goods being stored, the two sensors are embedded in a reference unit which
is filled with liquid. This simulates the temperature time lag found in the goods.
The temperature alarm is activated when :
●
the average value of the two temperatures detected does not fall in the set area (COLD alarm - WARM alarm),
●
one of the two detected temperatures does not fall in the set area even if the average value is within the acceptable margin,
●
both of the values do not fall in the margin
●
When the alarm starts there is an audible alarm and the respective alarm-LED starts to flash
●
(Alarm-COLD or Alarm-WARM). On the display the temperatures of the two sensors appear suc-
cessively at regular second intervals.
By pressing the „RES" key the audible alarm is discontinued, the flickering light display of the two
●
temperature values indicated by the sensors continues as well as the flashing function of the
alarm LED until the temperature irregularity is eliminated. If this does not happen within 20 minu-
tes the audible alarm goes off again.
The alarm turns off automatically as soon as the temperature goes back to the normal values. To
●
warn the operator of the fact that the alarm has gone off, the LED-Mem continues to flash until
the temperature is read by means of the Memory function.
15
The maximum and minimum temperature shown after the last ignition can be determined with the
●
help of the „Memory" function. For this purpose press the „MEM" and „WARM" keys simulta-
neously for the maximum temperature and „MEM" and „COLD" for the minimum temperature.
The „Memory-COLD" or the"Memory-Max" LED turns on displaying the relative value.
To cancel the memorized values press the „MEM" and „RES" keys simultaneously. The „Memory"
●
LEDs turn on and the two values are cancelled.
16
If the voltage should be discontinued (for having disconnected the plug or due to a breakdown in the safety
●
valve), the green LED turns off on the command panel and the red LED begins to blink. Furthermore, the
audible alarm is activated. It can be deactivated temporarily with the „RES" key.
During the „AC-fail" phase no temperature is displayed. The temperature measurement continues and the maxi-
●
mum and minimum values can be recalled as soon as the network voltage is present (see „Memory").
When the network voltage is missing the set data cannot be modified or cancelled.
●
If during this phase there is a temperature increase the „WARM-Alarm" LED as well as the red „AC-FAIL" LED
●
will flash.
