I have the first time my radiator equipped with electronic control. After 5 days I have it dismantled. The cultivation and programming were completely unproblematic. Thanks to the adapter allows the regulator mounted quickly. However bothers me that there is only one 'full-on' and full zu'- control. The drive moves the stroke full on or completely. So it can happen that my heating pump in their own 'juice' is running, because it pumps only against closed thermostats. Furthermore bothers me the relatively loud sound of the servomotor. There are also quieter drives, as I know. Also, I find it disturbing that can be the controller program only every hour. There is no way to enter a time to the minute.
