ECKELMANN UA 410 L Series Operating Instruction page 30


Before the connection to the case controller, all participating BT 30 temperature displays must be
addressed using the two lead-out wire jumpers.
Practical tip: If all four BT 30 are configured the same (e.g. all wire jumpers closed = address 1), all
BT 30 display the same temperature.
Further information and connection notes for the BT 30 can be found in the
30.
Symbols and parametrisation
In addition to the temperature, the current status of the controller and the cooling is displayed using symbols.
Firmware V3.00
Display of the current temperature: The temperature values in the temperature display can be
impacted with a correction value (parameter "Offset", see Menu 6-2-2) in order to be able to
compensate for differences between thermometers in the refrigerated case and in the display of the case
controller.
Note: This correction value only concerns the display; the actually measured temperatures are not
corrected. This correction value has no influence on the regulation (cooling, defrost etc.).
Symbol "Defrost": A defrost symbol is displayed during the defrost. The last measured temperature
value is shown in the display for the duration of the defrost.
This also applies during any possibly set wait time. The current temperature is not displayed again until
15 minutes after the end of the defrost. The drip time does not extend this delay time of 15 minutes.
Symbol "Snowflake": Controller in cooling operation (cooling active)
Symbol "Alarm": An alarm is pending!
In order to counteract any uncertainty on the part of the public, the parameter "Alarmsymbol" (menu
6-2-2) can be used to activate or deactivate the display of the alarm symbol.
