We use two of these controllers on the farm to heat material to 80 F during the winter. Recently we have had a couple of power outages and when the power came back on the controller reset to over 122 degrees … it is not always the same but it is always over 80 F. We had some product that was ruined and had to be thrown away - right now I can’t trust them until the problem is resolved.
I would rather they never come back on after a power outage, than overheat and cause a potential fire hazard.
It seems like there should be a setting to input a default temperature in case of a power failure.
