Sounds like the exact reason for me to get their probes vs. BRS and the original info I was looking for. Thanks! If coupled behind another controller like the Inkbird or even better a Hydros or Apex, then it's tons of redundancy and smart feedback which is fantastic.So the plus with Helios elements is that the ceramic heating elements are temperature specific. And there is a probe inside the element that monitors the temperature. The fail safe is if the element probe and the sump probe are different. Then it shuts down. I think by design it would be impossible to have the element to stick on because it needs the feed back loop to operate.
