5. Electrical power supply cold room
A 4-pole socket outlet is located on the intake-side of the Refrigeration evaporator unit for the electrical power supply to the
loads attached to the coldroom, with a total power capacity of
max. 250 VA (lighting, door frame heating).
The door contact switch can also be connected to this sokket
outlet.
5.1 Connecting the door contact switch
The evaporator ventilator should be switched off when the
cold storage cell is opened. For this reason, we recommend
the installation of an potential-free door contact switch (switching capacity 230VAC, min. 0.5 A).
Connection takes place via the 4-pole socket outlet mounted
on the intake-side of the evaporator unit.
In its delivered condition, the unit is functionally ready for
service without an external door contact switch.
The door contact switch is not included within the scope of
delivery of the unit.
If a door contact switch is connected to the refrigeration unit,
the regulation parameter must be changed (see also Point 9.3,
Menu Settings).
This is achieved through the following menu items:
The electronic control unit is outfitted with a potentialfree
Fault report contact for connection to the on-site Fault reporting equipment (max. 10A, 230VAC). The mains side electrical
power outage is not monitored.
In the event of a fault, contacts IN and NO are closed.
The connection is located on the circuit board (plug connector
X4).

5.3 Power supply connection and commissioning
Attention!
The electrical power supply should first be connected at
commissioning - Risk of life!
Work on the power supply connector and protection devices
must be carried out by a specialist company, in accordance
with IEC 364, local regulations and the connection conditions
of the respective energy supply company!
Insert the mains plug into a properly grounded outlet with
personal protection measures (fault current circuit breaker)
according to the specification plate.

Electronic regulation
The equipment starts up after self testing the regulation.
A warning signal sounds upon ramping up the regulation.
Unless other selection is made during ramp-up, the regulation
continues with the status which was set before discontinuation of the power supply. I. e. if regulation was in a cooling
mode, it continues in the same mode. If it was in standby, it
will remain in that mode.

6. Defrosting
6.1 Defrosting process
When the defrost function activates, the compressor and the
fan are switched off and the heater for the defrost water hose
is switched on.
Once the defrost water hose lead time has passed, the compressor switches on and the bypass valve opens. The heater for
the defrost water hose continues running during this process.
The compressor remains running until the set defrost temperature is reached in the evaporator unit or the set maximum defrost period has passed. The maximum defrost period should
usually be set as a longer period rather than shorter one so
that defrosting occurs in full. The correct position and thermal
contact of the sensor in the evaporator unit must be checked
during maintenance (see figure).
The sensor is inserted diagonally downwards from the left
between the 9th and 10th fins and the 1st and 2nd sensor tube
at a depth of 34 mm.
If the sensor is positioned against a tube that is close to the
inflow during the defrosting process, defrosting does not
complete fully. The sensor reaches the set defrost temperature
prematurely and the control unit terminates the defrosting
process. The ice is simply melted and sinks to the bottom. This
results in a block of ice on the lower edge of the evaporator,
which can only be manually defrosted by a service engineer.

Caution!
When using hot gas defrosting, the process should best be
conducted quickly and often. Large ice formations cannot
be melted as the defrosting process works with far lower
temperatures and therefore less radiant heat.

6.2 Defrosting options
Defrosting cycle
The defrosting process is continually triggered at set
intervals.
Defrosting plan
Defrosting is performed for well-defined periods. These
can include 99 periods will be specified in a week time.
Manual defrosting
The cooling process is interrupted and a complete defrosting process is conducted. The unit then re-activates
the cooling mode.
6.3 Defrost water drain
The defrost water created is caught in the defrost water
tray and largely evaporated by the evaporator loops.
In the event of large volumes of defrost water or high
humidity around the cell installation site, the use of
the evaporator may not be sufficient. In such cases, an
additional defrost water drain hose can also be attached
to the evaporator tray. The accessories kit is optionally
available and is compatible with all FS and CS series
units.
- The air flow should not be directed at the doors and
pressure compensation valves. Pressure compensation
valves must always be installed in a position where
they are barely influenced by the air flow.
- The goods introduced must be stored in sealed containers. Goods with high water content are subjected to
dehydration and thus damage. (Freezer burn on deepfrozen goods and shrivelling/drying out of fresh foods)
- Do not leave deep-frozen goods in the warm storage
area on delivery. Defrost water will form on the surface
and have to be cooled again. In the case of cardboard
packaging, a great deal of moisture is absorbed in the
surfaces and causes the evaporator to freeze over when
the packaging is moved into the coldroom.
6.4 Preventing excessive defrost water
Defrost water is the melted ice formed by the evaporator. In other words, the ice was formed through a use of
energy and likewise melted again. Due to the thermodynamically induced lack of humidity at the coldest point
in the coldroom, ice formation cannot be prevented
(vapour pressure drop) but can be minimised.
The following points should be noted:
- Units in deep-freezing rooms should always be coupled
with a door contact switch that switches off the evaporator while the door is open.
- Doors should remain open for as little time as possible.
If this is not possible, suitable measures must be taken
to minimise the loss of cold. This can include several
technical measures such as strip curtains, fast-sliding
doors, air curtain systems, pre-cooling rooms etc.

7. Cooling mode
7.1 How the cooling mode works
After switching on the unit (Standby => No; see Point 8
‘First steps’), the cooling mode activates. If the unit was
only recently connected to the mains, the compressor
standstill time (usually three minutes) passes. The compressor then switches on and starts the cooling process.
The condenser fan switches on at an appropriate speed
depending on the temperature at the condenser outlet.
On reaching the ‘Start evaporator fan’ temperature or
upon expiry of the ‘evaporator fan delay’, the evaporator
fan switches on. Depending on the humidity setting, the
fan runs at all times or when the compressor is switched
on (see parameter list in Point 9.3). The compressor runs
until the switch-off point is reached and re-activates
when the temperature increases to the switch-on point.
The points are determined by the desired coldroom
temperature and the hysteresis (see parameter list in
Point 9.3).
7.2 Description of the cooling mode types
Normal mode
The unit is started with ‘Standby = No’ then runs continuously. The cooling mode is only briefly interrupted by
the set defrost cycles.
Cooling schedule
The unit is started with ‘Standby = No’ then only runs at
the times approved in the cooling schedule. The cooling
mode is only briefly interrupted by the set defrost cycles.
The cooling schedule must always be programmed for a
week.

Description
After changing the language setting, the unit must be
restarted.
Up to 8 di erent languages can be stored. The
standard languages are German, English and French. In
order to activate the changeover to another language,
the language must be selected and then, the equipment
disconnected from the power supply for a short time. Upon
restarting, the new language is activated.
A name can be assigned for each refrigeration unit. In the
case of bus operation, inputting the name for the assignment of rooms is helpful. In addition to the name, the unit
number has to be input at the DIP switch, as well. Since
up to 8 di erent refrigeration units can be controlled with
one display, a logical structure of the name speci cations
is de nitely required. (See Electrical circuit diagram, Page
66 to 69)
The evaporator fan runs together with the compressor.
=> Low relative humidity.
The evaporator fan runs constantly.
=> High relative humidity.
Di erntial can be changed between switch-on and switcho temperature. If the value is negative, the refrigeration
unit switches o if the cold room temperature has reached
the rated temperature value minus the absolute value of
the di erntial. It turns on if the cold room temperature has
reached the rated temperature again.
Example: Rated temperature - 20°C
Di erntial -2K
Refrigeration unit O at -22°C
Refrigeration unit On at -20°C
If the value is positive, the unit turns o if the cold room
temperature has reached the rated temperature value.
It turns on if the cold room temperature has reached the
rated temperature + di erntial.
Example: Rated temperature +5°C
Di erntial +2K
Refrigeration unit O at +5°C
Refrigeration unit On at +7°C
If the units are used in bus mode, a separate unit number must
be set for each unit (see circuit diagram on pages 66-69)!
Redundancy = all units run with the same setting and temperature. Defrosting and cooling occur simultaneously on all

Defrosting cycle: the defrosting process starts at a specified
interval.
Example:
Every 2h defrosting cycle for a duration of 30 minutes
=> at 2:00 pm, defrosting is performed for 30 minutes,
at 4:00 pm, defrosting is performed for 30 minutes,
at 6:00 pm, defrosting is performed for 30 minutes.
For limitation on defrosting, the defrosting limitation
temperature is also applied. Thus, defrosting is performed
for a maximum period of 30 minutes or until the defrosting
limitation temperature is reached. It is better to defrost the
units quickly and often than to have a long cycle period and
a long defrosting process.
The defrosting limitation temperature is measured in the
evaporator. For switching o , the defrosting duration (time
in min) or the temperature is used. Whichever value is
reached sooner.
If no defrost termination probe is available, only the time
is considered and the process is nished after running the
defrosting sequence.
Switchover between hot gas and fan-only defrosting.
The temperature speci es up to which temperature the
defrosting is only performed with the evaporator fan. Under
this temperature, defrosting is performed by the use of hot
gas or electric heating, respectively. Above this temperature,
the ice layer on the evaporator is melted away for cooling of
the room. For that purpose, the evaporator probe must not
be fully frosted. Defrosting using the fan should ideally only
occur for chiller rooms.

9.5 Menu LogBook
9.5.1 Mode of operation
All recordable faults are documented in the log book and stored in a continuously updated ring memory. Depending on the
volume, the faults are stored for at least three months and then overwritten. The data can be exported and evaluated (*txt format). The data in the memory cannot be deleted. For a better overview, the day on which a fault occurred is underlined in the
date selection. Once this day has been selected, the temperature display or the event display can be accessed.
The temperature data (optional) is also recorded. The ring memory can last for two years with a 15-minute recording interval.
After two years, the oldest data records in the ring memory are overwritten. The logged data can be directly output onto the
display or read via a data carrier. The data (* .txt format) can be imported into a spreadsheet and evaluated. The data in the
memory cannot be deleted.
9.5.2 Licence release
If the data logger is retrospectively ordered, the display number must be reported to the factory. The display number can be
found under Settings, Control panel, Licence. This display number is allocated to a release number in the factory, which is entered under the display number. Once the release number has been entered in the display, the temperature data is recorded.

10. Bus mode
10.1 Connection of the units and the display
The units are connected together using a CAT5E data
cable and an RJ45 plug connector. The display must
always be connected using the upper socket (see circuit
diagram). A bus address must also always be allocated to
each unit (binary code address on the controller board
via DIP switch, see circuit diagram). If the units should
be supplied with power via several electrical circuits,
external potential equalization is required (min. 6 mm²).
The potential di erence must not exceed 2 V. If this does
not occur, the data connection can be destroyed and the
cooling mode disrupted.
10.2 Bus operation modes
- Bus type: multi-cell
Up to eight coldrooms with di erent temperatures can
be managed on a display. To better allocate the units to
the rooms, the units can be given a name (see parameter
list).
- Bus type: redundant
The units run jointly in a coldroom with the same parameters. For FS and CS units, the model ‘wall-hanging unit’
must be selected (see parameter list). The model controls
the defrost function so that all units are simultaneously
defrosted. If the option ‘ceiling unit’ is selected, the units
defrost at di erent times. For wall-hanging units, this
would lead to ice formation.
10.3 Bus operation faults
In the event of outages within the network, the units
always continue running with the last parameters to be
transmitted from the display. When the connection is
restored, the system automatically adjusts.

10.4 Mains connection
The mains connection is located on the circuit board in
the housing. To connect the unit, the housing must be
opened and connected using a suitable data cable.
The control unit can be connected via a mains cable. The
connection occurs via a web browser and the appropriate
IP address. Access is gained by entering the username
‘admin’ plus the applicable authorisation number (1234
for users and 90210 for service personnel). Internet access
must be accordingly released. This occurs via the IT support team at the installation site.

If the message ‘Package detector fault’ appears, a check must be conducted
to see if the evaporator is covered in ice. Before replacing the detector, first
remove the ice and check the detector’s position. The detector must not touch
the evaporator’s tubes. If the detector touches the tubes, the defrost period
is too short and the ice does not melt as the defrost temperature is reached
prematurely.
The safety pressure switch (pressostat) has been activated. If the fault does

Check whether too many warm items were brought in for storage.
Is the evaporator icy? Initiate manual defrosting and afterwards check if the
evaporator is free of ice.
Is the alarm limit to close to the hysteresis?
Is the delay time set too short?
Check, if the cold-water circulation (with devices with plate heat exchanger) is

air (air exchange).
Check the temperatures in the cool room. Was the temperature adjusted
lately?
Were large amounts of goods brought in that had a signi cantly lower temperature?
Are the siphons lled with water?
Initiate manual defrosting and watch whether the evaporator is free of ice after
the process is complete.
If it is not,
- The defrosting cycle is too long and the defrosting time is set too short.
- The defrosting limitation temperature is set too low and prematurely turns o

- Check whether the door closes correctly and is air-tight. Adjust if necessary.
- Check whether the pressure compensation valve is ok.
- Check whether the pressure compensation flap closes properly
- Check whether the filter fleece is correctly positioned
- Check whether the package detector is correctly positioned (not touching
the evaporator tubes)
- Check whether moisture has infiltrated through the delivery of goods or personnel movements
- Check whether the cell environment is extremely damp (vapour pressure)
The door was opened for longer than released by the monitoring time. If this is
not the case:
Is the door contact switch installed and activated by the door?
If the door contact switch is not installed, the position “Door Contact Switch” in
the “Settings” menu / “Alarm Limit Values” must be set to “No”.
In this menu you may also set the alarm time for the door.
Prevent leaving the doors open for long periods as this leads to ice formation
on the evaporator and the cell.
