At least you’re getting fault flags;

I have a fair number of PTC1’s in my inventory now and every so often we’ll have a spate of all outs and there is very little in the controller log – sometimes nothing at all, to explain why the signals are off.

However, it is usually due to either a mains spike or momentary brown out; 950’s appear similarly susceptible, but they tend to log it as a correspondence error on reds (IIRC) usually.

Had a spate of all outs a few months back over the course of about a week that affected not only us but one of our neighbours as well (same contractor) all with similar presentation in the controller logs.
