It has been connected during the winter months to an electric heater in the greenhouse to a minimum temperature of 5 ° followed precisely. The battery lasts forever, the device measures accurately.
Now his time was probably over and I bought the same device again.
Funnily enough, the text is in the manual is still the same.
And I get admittedly still always the Rappel, if I need to adjust the machine. If yes, but only once a year.
I am glad that I do not need the other setting. The guidance does not match any of my logic ... ;-)
The long cable to the sensor at the end makes sense. So you can measure the temperature where you want it and not only in the area of the socket.
I hope for the next 10 years!
