No. On the Thermonom 6 this message is normal at start-up: the channel board boots faster than the display board and finds no receiver on the CAN bus for the first moments. The number in front of the message is the count of telegrams discarded in the process.

On devices with more than one channel board the message does not occur. If it does appear there, or if it appears during operation rather than only at start-up, please contact customer service.
