Changes Face-lifting models to Greenline models:
Automatic defrost -cycle and design
Changes Greenline models to Previous models: cooling unit, the heating
cartridge, lighting, insulation and electronic controls (Fuzzy Logic).
2.0
Electronics
2.1
Fuzzy Logic
All Greenline models and Facelifting models maintain a constant temperature level which has been set at the beginning
of operation. This temperature level is controlled by
electronic “intelligence” in an energy-saving way.
Unlike conventional appliances, the electronic control
A
component does not switch on and off but controls (clocks)
the cooling unit’s heating power in a way which does not
require system circulation to be interrupted.
The electronic control’s sensor (A) is an air sensor. This means that the
sensor can react directly to the temperature inside the cooling appliance.
2.2
Fuzzy Logic with 2 sensors
By means of the second sensor the electronics carries out a leak detection
test. If leaks or blockages in the cooling unit are recognised the miniBar is
shut off by the electronics. The test is done after every defrost cycle
(every 24 hours).
After a Power-On-Reset, the controller’s software runs a self test routine to
check the function of the sensors. The result of the test is shown with the
length of the first duty-cycle of the heating element (jumper X4).
There are four different states which are shown in the following table:
3
Status
both sensors o.k.
air-sensor missing/defective
evaporator-sensor missing/defective
both sensors missing/defective
In service case please pull sensor off

If the air-sensor fails during normal operation, the software shuts down the
cooling unit in steps to “0”.
In refrigerators without evaporator-sensor or if the evaporator-sensor is
defective the leakage test is not carried out.Then the new electronics works
like the previous one without leakage detection.
Do not change the
connections of the
evaporator-sensor and
the air-sensor !

Automatic Defrost Function
The electronic also regulates the automatic defrosting of the refrigerator.
When the plug has been stuck to the socket the running time of the
refrigerator up to the first defrosting is 15 hours for greenline models
and 39 hours for the new face lift models (RH4XX). For all models the
defrosting takes 2 hours. Then the refrigerator works 22 hours and
afterwards defrosts 2 hours. Therfore the starting of the refrigerators
determines the time of defrosting.
For example: Starting at 7.00h = first defrosting 22.00h - 24.00h (for facelift
models 22.00h next day)
(39h)

Cooling Unit

Heating Shell
The cooling unit has been optimised for the Greenline models and FaceLifting models. Unlike the cooling units of its predecessors, the Greenline
models and Face Lifting models cooling units can be replaced.
When replacing the cooling unit, however, the heating element
(heating shell) must be replaced as well.
Ammonia is used as a coolant. This is a natural compound also used in house
hold cleaning agents (1 litre of Salmiak cleaner contains up to 200g of
ammonia - about twice as much as is used in the refrigerator). For the safety of
hotel guests and personnel, it has been established by inspectors that the
coolant poses no threat to health.
The conventional heating element (previous models) is replaced by a heating shell. The heating shell is situated directly to the cooker tube. An optimal
efficiency ratio is achieved by means of a direct and enlarged contact area.
In case service is required:
142 mm
Attention please! The heating bowl’s upper
edge must be placed at the shown position
(142 mm).
Install the mounting clip at the centre of
the heating shell.

Lighting (except for RH 356LD/E, RH 456LD/E)
All Greenline and face lifting cooling appliances are equipped with sensorcontrolled lighting. The lighting’s sensor (proximity switch, A) is activated by
means of a magnet (B) which has been foam-installed into the door.
The lighting mechanism consists of two lamps for 180-250V operation
switched in series. For voltages of 100-140V, the lamps are switched in
parallel by means of a bridge.

At an average room temperature of approx. 22°C, it is sufficient to
operate the miniBar with an average thermostat setting.
If possible, always store pre-cooled goods.
Do not expose the miniBar to direct sunlight and do not place it close
to a source of heat.
An unobstructed air circulation in the fridge aggregate must be
ensured (ref. chapter “7.0 Installation”).
When removing goods, only open the miniBar briefly.
Switch on the miniBar approx. 12 hours prior to stocking.

HiPro Generation
HiPro models are the latest generation of miniBars and consume
approximately 15% less energy than the RH4XX models.
Technology and design defined with a new name :
HiPro Technoloy!
HiPro means High-Professional, High-Protection and High-Profitable
Technology.
HiPro models:
HiPro 3000
HiPro 4000
HiPro 6000
Changes HiPro compared to Face-lifting models:
- absolutely new design with modular shelf and
drawer system
- different outer measures
- error detecting via flashing signals
- fixed indoor temperature
- modified cooling unit
- better isolation
- all plugs connected to the electronic are encoded
- door sealing replaceable
- less energy consumption
19.0
HiPro Electronic
After connecting the electronic with the main supply (hard ware reset)
following actions take place:
- initialization of the hardware
- values of resistance are read in
- self-test
- initialization of RedDot and function test of cooling unit
Error status is signalised by flashing of the indoor lighting and,
if available, the REDDOT_LED.
19.1
Temperature in the HiPro compartment
Set up of the desired cold-storage area temperature.
The cold-storage area temperature is set as follows:
- for Europe
5°C
- for USA
3°C
Cold-storage area temperature can be readjusted with the help of the
remote control by via the sensors.

When operated, the electronic measures the temperature of the indoor air
sensor (NTC) and controls depending on this, the heating efficiency of the
absorber with the help of the HiPro-Electronic .
19.2
Self-test of the electronics
After switching on the supply voltage (Hardware- Reset) the software
carries out a selftest, in which the value of resistance of the NTC-sensors
(air-sensor, evaporator sensor) are measured.
In case the value of the resistance measuring is not corresponding
to the values of resistance fixed by the software, an error is
signalized.

a red point!
19.3
Automatic fault analysis
The type of error is signalised through “n” flashing impulses of the inner
lighting (P_LIGHT) as well as REDDOT_LED with a frequency of 0.5 Hz, as
shown in the following table:
Type of error
Number of flashing impulses

With the help of a reset you can see the fault signal (n) again.
In case an error is recognised (n>2), the temperature adjustment will not be
started, and the heating element will not be switched on.
The inner lighting and the “Red-Dot” will flash with ca. 4 Hz.

19.4
Automatic Defrost Function
The HiPro electronic also regulates the automatic defrosting of the
refrigerator. When the plug has been stuck to the socket the running time of
the refrigerator up to the first defrosting is 39 hours For all
models the defrosting takes 2 hours. Then the refrigerator works 22
hours and afterwards defrosts 2 hours.
Therefor the starting of the refrigerators determines the time of defrosting.
For example: Starting at 7.00h = first defrosting 22.00h (next day).

Cooling unit check
In order to carry out the check of the cooling unit, e.g. a leak within the
cooling circle, the temperature difference at the evaporator sensor is
determined every 40 minutes. If, after finishing the defrost phase the fridge
does not reach a cool-down of 4K within 40 min, a system error exists,
and the fridge is switched off.
The system error is saved in the EEPROM and indicated by permanent
flashing of the indoor lighting as well as the REDDOT_LED with 8 Hz.
System errors are:
- Leak / clogging of the cooling unit
- the HiPro is not balanced
- heating element defective
In service-case the cooling unit is not changeable. You have to
install a complete new HiPro miniBar!
19.6
Heating Shell
After max. 5 seconds, the heating element is driven with supply voltage and
works for 20 seconds. This cycle is repeated for 45 minutes. After this the
electronic controls the prefixed temperature.

Lighting (ca. 7,6V) and Infrared sensors
Two LEDs (A) light the
cooling compartment whilst
the door is opened.

Two sensors (B) control the
LEDs as well as the
(optional) door control.

Change of lighting / Infrared sensors
The complete lighting is fastened into the
inner housing with a clip and can be pulled off
very easily. Detach the plug connections and
change the lighting. Same is applicable for the
infrared sensors. All plugs are encoded.
21.0
Automatic Door Control
The LED (A) placed at the bottom edge of the minibar
indicates whether the miniBar door has been opened.
The electronic contains an infra-red reflecting light barrier for recognition
“fridge door was opened”.
For resetting the REDDOT-indicator
A
use the remote control.
The reflecting light barrier is checked
every 200 ms.

If possible, always store pre-cooled goods.
Do not expose the miniBar to direct sunlight and do not place it close
to a source of heat.
An unobstructed air circulation in the cooling unit must be
ensured (ref. chapter “7.0 Installation”).
When removing goods, only open the miniBar briefly.
Switch on the miniBar approx. 12 hours before stocking.
