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 assign-
ment 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 diff erent refrigeration units can be controlled with
one display, a logical structure of the name specifi cations
is defi nitely required. (See Electrical circuit diagram, Page
66 to 69)
The evaporator fan runs together with the compressor.
=> Low relative humidity.
Low
The evaporator fan runs constantly.
=> High relative humidity.
Diff erntial can be changed between switch-on and switch-
off temperature. If the value is negative, the refrigeration
unit switches off if the cold room temperature has reached
the rated temperature value minus the absolute value of
the diff erntial. It turns on if the cold room temperature has
reached the rated temperature again.
Example: Rated temperature - 20°C
Diff erntial -2K
Refrigeration unit Off at -22°C
-2K
Refrigeration unit On at -20°C
If the value is positive, the unit turns off if the cold room
temperature has reached the rated temperature value.
It turns on if the cold room temperature has reached the
rated temperature + diff erntial.
Example: Rated temperature +5°C
Diff erntial +2K
Refrigeration unit Off 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 tem-
perature. Defrosting and cooling occur simultaneously on all
units. Redundancy in this context means that if one unit fails,
the second or remaining units continue to function. The units
do not monitor each other.
Multi-cell = all units are controlled via a display. To facilitate
allocation, each room and the applicable unit should be given
its own name.
To switch to a different bus mode, the unit must be disconnec-
ted from the mains. On restarting the unit, the new bus mode
is activated.
