4. The procedure of exiting the defrosting mode is terminated with the activation of fans, turning off the „dF”
symbol on the display and turning off the green LED blinking on the pushbutton .
5. Should the fans be absent or not connected to the S.C.C.B. system, the unit will act as if they are installed.
6. The defrosting process will be terminated following the achieving of the evaporator temperature as preset in
the ‘d2’ parameters, or if the time preset by the ‘c1’ parameter has been exceeded.
7. Having turned off the „dF” symbol and terminated the defrosting process, the display will show the
temperature as stored right before the defrosting commencement, for the period of time as specified by the
‘c7’ parameter – this is intended for preventing claims with respect to “violent temperature fluctuations in
the unit”.
8. The unit performance is the same as in the case of manual and automatic defrosting.
9. The ‘r0’ parameter enables an override to turn the fan on during defrosting.
10. During defrosting there is no fan control based on the ‘d6’ parameter.
C – The Door Opening Sensor Operation Principle
1. If the door has been opened, the fan will be stopped immediately. In addition to the above, depending on
the ‘r7’ parameter setting, the light may be turned on in the G-202-P00 unit. The display shows the
temperature.
2. If the door has not been closed, after 30 seconds, the “dr” symbol will be constantly lit on the display. If
the buzzer is installed in the controller, the short lasting sound signal will be repeated every 30 seconds.
3. If the door continues to be open after the time as specified in the ‘r8’ parameter, the alarm will be
activated, which will be signalled by the display blinking with “dr” symbol, and with the sound signal if the
buzzer is installed. This is when the compressor will be turned off.
4. If the R8 = 0 the alarm will be activated immediately after opening the door.
5. The alarm may be silenced through pressing any pushbutton. Closing the door deactivates the alarm and
normal operation is resumed.
6. The controller allows connecting both the door opening mechanical sensor (R6=01), and the mechanical or
magnetic sensor, disconnected in the course of door opening (R6=02).
D – Hysteresis
When programming the‘d0’ i ‘d1’ parameters (the minimal and maximal user preset temperature) attention
should be paid to the fact that the ‘d3’ hysteresis value causes additional shifting of the temperature to higher
or lower values with relation to the user preset temperature level.
This is particularly significant with regard to the so-called “plus” equipment which should always be operated at
the temperatures above 0
