XII. OPERATION OF G-201: FOR USERS
1. When the unit is connected to mains, two dots will appear on the display for a second, then the
version of unit software and dots for another second. Then, on middle segments of the display two
horizontal lines which signal connection to mains appear. The unit is started when the button
is pressed. The value of temperature in the unit appears on the display (temperature reading from
the chamber sensor).
2. Setting a defined temperature .
When is pressed, programming is begun, the value of set temperature appears and a diode
appears at the button .
When
are pressed, the set value can be changed within the range programmed by the
producer of the cooling unit.
When is pressed, newly set value will be memorised and the controller will return to its normal
operation.
If G201 is switched off during programming, it won’t memorise the new setting.
3. Switching on/off of lighting.
Pressing of the button
causes switching on/ off of the light. It is signalled by a green diode at the
button. The button works independently of the thermostat switch - .
4. Switching on of manual defrosting.
Defrosting is switched on manually when the button
is pressed. Then a green diode is switched
on on the button; the ‘dF’ symbol appears on the display.
Defrosting will end automatically after the required time or when the required temperature
programmed by the producer of cooling equipment is reached.
5. Alarms.
If one of the symbols below appears on the display:
A1
A2
it means a breakdown of the control and service should be called.
If the symbol
A4
is displayed alternately with temperature it means that the unit has too high temperature and it
should be checked what is the reason of the alarm (open door, sunlight) and the condition of
products should be checked.
If repairs are done on one’s own, guarantee will be lost and it might cause electric shock
and other dangers. Therefore, all repairs should be done by trained and authorised service
personnel!!!!
