I suddenly have an alarm on my temperature and on the P4 and Touch it shows Temp ***

Does this mean the probe has failed? If so, I assume as it is under a year old it is under warranty. Is there anything I can try to test it?

Meanwhile, as my heaters are heater stats, I will set them to always on and let the heater stats take control of themselves until this is sorted.

Oh, and I have made no changes for weeks to the software and noe of the kit has been disturbed.
