In firmware release V104 (the FW version is on the device label or in the device mask in ModComTool) there is a minor bug: If a slave controller is set up as Slave, the master outputs are not mirrored at the slave controller. For a Master – Slave topology, all Slave controllers must be configured as Master.
Slave addresses (10, 11, 12… etc.), setup of Master controllers, and wiring remain unchanged, see datasheets.
The problem affects room controllers FC010, FCR010, FCR011, FC013, FCR013 and derived customised versions with serial numbers of the range from 131100 to 135044. We apologize for any inconveniences. Contact firstname.lastname@example.org for more information please.
