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 operating manual of the BT
30.
