Have some time ago 6 of radiator thermostats bought and mounted. The setting was super easy as the installation. The programming options leave nothing to be desired. The reliability of the thermostats is very high. The set temperatures are thanks to the learning function at the set time is reached and maintained absolutely correct. The window function also works very well. The servomotor runs audible but absolutely not disturbing. All 6 units still work to perfection. I had previously EQ3 thermostats in use. These had to be replaced all part repeatedly within one year. Not once worked for 12 months without failures. After I then the collar had burst I have replaced all thermostats with this product and as I said: "I am completely satisfied and thrilled!"
