Note:
The upper control button “>” is used to select the appropriate function. The selected function is
switched on and off using the lower control button "<". The test program serves the purpose of
checking the controller functions and system components. After 12 min. have elapsed without a
button being pressed, the control will reassume its last configured functions and return to the user

Note:
The system monitoring provides early warning of system faults before the malfunction occurs and
protects goods against damage. By tracking the block temperature during the cooling process, a
performance reduction of the cooling plant is already detected in the beginning and signalled by the
alert “ECO”.
Note:
With “SLb” und “SUb” the adjustment range of the setpoint temperature under the item “tSr” can be
limited. In conjunction with the password “P__” a manipulation of the setpoint value (control level 1

Configuring the goods protection program is only possible in the case of electro- or
recirculating air defrost. In the case of recirculating air defrost the heating is done by an
additional heater.
Goods protection program on, following setpoint, with early low temperature
warning (FSL)
To protect goods from low temperature (e.g. otherwise resulting in freezing), the goods protection
program is initiated after the temperature has fallen below the actual setpoint, even if a setpoint
correction is configured. If the room temperature falls more than 0.5 K/0.9 °R below the setpoint, after
a maximum of 12 minutes the cooler fan is started. If the controller detects an ongoing negative trend
of the room temperature in a time window of 18 minutes, the heating is switched on additionally. At the
same time the low temperature warning "EGP" is displayed by the controller. If using hot gas defrost
(menu item "cd", "HGE" or "HGS") only the temperature is monitored, the defrost relay remains
unswitched.
Goods protection program on, with early low temperature warning (OnL)
In contrast to the previosly described procedure for the goods protection against low temperature,
now the lowest setpoint is relevant for the monitoring. Here the correction value must be paid
attention to, when setpoint correction is used. The further procedure is the same as described
previously ("cGP", "FSL").
Goods protection program on, following setpoint (FS)
See ("cGP", "FSL"), however without early low temperature warning. The low temperature warning
"EGP" is displayed, after the heating/heater remained on for at least 60 minutes without interruption.
Goods protection program on (On)
See ("cGP", "OnL"), however without early low temperature warning. The low temperature warning
"EGP" is displayed, after the heating/heater remained on for at least 60 minutes without interruption.
Goods protection program off (OFF)
Room temperatures below the setpoint are not monitored.
Note:
The setting "FSP" together with the setpoint correction "cSS" could also be used as an unfreezing- or
heating program. In the case of single sensor control ("cS","cSS") the goods protection program is
not taken into account.
Attention: When using defrost communication with the digital inputs 1 or 2, the goods protection
program should not be configured. Nonobservance results in the alert "EUS".
