Super !! No frozen water pipe more

The delivery of the thermostat was quick. The setting was just for me and it works flawlessly. Thus we have a small electric heater (500 W) controlled in a wet well. We have set an initial temperature of 6 ° C and stop is at 12 ° C. Even at -17 ° C no frozen line and our horses have even slightly tempered water in such cold weather.
Had not thought that with as little effort as much to achieve.
