1.
Display:
1.1
Refrigerator shall display actual temperature during initial power
supply and after temperature reduces to the minimum value and
before increasing to setting temperature which corresponds to such
temperature gear.
1.2
Current actual temperature is ±2°C of setting temperature for gradual
variation to setting temperature. Display temperature will change to
actual temperature gradually without temperature variation jumping
under normal conditions if current temperature exceeds setting
temperature by 2°C. Variation is ±1°C /min during all temperature
variations;
1.3
Please conform with Clause 3 during setting alternation;
1.4
Displayable scope of display board refrigerator is 50℃ to -45℃.
Adjustable scope is 20℃ to -40℃.
1.5
Please conform to Clause 4 for over-temperature alarm and sensor
trouble alarm.
2.
Color definition of indicator lamp:
(As shown in display effect diagram), display is a 3-bit digital display with 2
indicator lamps above it. It is alarm indicator lamp(ALARM) and it is on during
alarm. The other is output indicator lamp and it is on during press bootstrap.
The lamp flickers when temperature reaches bootstrap point but press has not
been started up due to delay. Please check if alarm or output indicator lamp is
on or not according to actual conditions during power supply of display board.
3.
Initial status:
Operation status for initial power supply is initial status.
Operating temperature of refrigerator: Default setting temperature is 4℃ and
lamp in it is closed. Display control board will display default setting
temperature and flickers by frequency of 1Hz. It will display actual temperature
of refrigerator automatically after 5 seconds. Press will not be started up if
refrigerator temperature is between bootstrap point and shutdown point during
initial power supply. It can not be started up until temperature reaches
17
bootstrap point.
There is no alarm if refrigerator temperature is within scope of alarm limit.
There is instant temperature alarm and buzzer will ring if refrigerator
temperature is out of control limit scope. Alarm lamp will flicker and alarm
sound can be cancelled by pressing alarm key. However, alarm indicator lamp
will keep flickering and it is off only when refrigerator temperature is within
scope of alarm limit.
4.
Temperature control
4.1 Temperature control
Bootstrap temperature = Setting temperature + Control temperature
difference, rd
Shutdown temperature = Setting temperature – Control temperature
difference, rd
“Output” lamp is on during press bootstrap and it is off during shutdown.
4.2 Press shall stop operation for 5 minutes forcefully if refrigerator
temperature fails to reach setting temperature if press operates for 4
hours continuously. Press can not be started up until 5 minutes after
shutdown.
4.3 Hot Gas Defrosting
To stop forced defrosting if accumulated compressor bootstrap period reaches
d2 hours if setting temperature exceeds 0℃. Fan in refrigerator normally
operates during defrosting and press will stop operation. Please start up it
again after meeting one of 2 conditions shown as follows:
Testing temperature of refrigerator Setting temperature+4℃
Defrosting period≥15 minutes;
Press will start up instantly after defrosting ends.
There is no defrosting demand if setting temperature is less than 0℃.
4.4 Setting Method of Refrigerator Temperature
Setting refrigerator temperature shall be adjusted according to following
method:
To press SET key then loosen it quickly so that display window can display
original design value with flickering. To press “+” or “-” to adjust setting value if
it flickers.
Setting value can vary by 1℃ by pressing it every time. It will exit automatically
18
and display refrigerator temperature again (without flickering) if there is no
operation within 10 seconds.
4.5 Setting of Internal Parameters
Several internal parameters can be adjusted by following method to guarantee
normal operation of refrigerator:
To press “regulate” key for more than 10 seconds to display original design
value (rd) with flickering; To press “+” or “-” to adjust setting value. Adjustment
scope is 1℃ to 4℃ because setting value can vary by 1℃ by pressing the key
every time. To press “alarm” key to exit and return to previous layer for rd
display. (To press “alarm” key to return to previous layer by pressing the key
once until return to refrigerator temperature display). To select next parameter
by pressing “+” or “-”. Internal parameters are shown in the 1st attached form.
Regulation method is as above.

4.6 Inquiry of the Maximum and Minimum Refrigerator Temperature
The maximum and minimum refrigerator temperature can be enquired by
following way:
The maximum or minimum temperature is actual temperature detected by
sensor, not the maximum or minimum displayed temperature.
Enquiry of the maximum value:
In the meanwhile, users can press “SET” key and “+” to display the maximum
actual value without flickering in the window. Please loosen any key to return to
display refrigerator temperature.
Enquiry of the minimum value:
In the meanwhile, users can press “SET” key and “-” to display the minimum
actual value without flickering in the window. Please loosen any key to return to
display refrigerator temperature.
Record mode of the maximum and minimum temperature: To press SET key to
cancel previous temperature record and begin to record the maximum and
minimum temperature again.
5.
Alarm Control
5.1 Refrigerator will carry out over-temperature alarm and buzzer will ring
during operation if refrigerator temperature is less than or equal to the
minimum temperature limit or more than or equal to the maximum
temperature limit without return to alarm limit temperature scope within 15
minutes. Alarm indicator flickers and users can cancel alarm sound by
pressing alarm key. However, alarm indicator lamp will keep flickering and
it is off only when refrigerator temperature is within alarm limit scope.
5.2 It shall alarm instantly and buzzer will ring if there is any sensor trouble.
Alarm lamp will flicker and window will display “EE” at the same time.
Alarm sound can be canceled by pressing alarm key but alarm indicator
lamp and “EE” display will continue. In the meanwhile, it can enter into
safety mode for compressor operation control according to internal
parameters dO and dF.
