Hi, I've had the same problem but shifted to the overheating (and not fortunately during the warm up, so i've been able to catch the temperature trend). trand). I'm not sure the "SmartMixing" always works well. Anyway, for my purpose, I solved (not in a brillant elegant way) by temporarly forcing Off the HW loop through an High Temp Turn Off availability manager.

I hope to manage a better solution, maybe with some other user tips. Regards, Alessandro
