Got myself this knob to replace built Bimetal thermostat in frost guard because bimetals usually work only to 5 degrees and then switch off again only at a temperature delta of 3 to 5 degrees - endurance and high costs that result when one of the fans would like to take Outbuildings shed (plants) or garage. In addition, the risk of short circuit and overheating increases. The unit I have a little fiddle properly connected. I should be careful just better at Electric customer. But everything is correctly described and should not be a problem. The programming was simple. Now the fan turns at exactly 0 degrees and 0.5 degrees again and I'm happy. The Delta then naturally you can. The temperature sensor operates very closely.
