I know that it works, probably 3 minutes when circulating to radiators, and much longer when circulating to the floor heating, how much? I didn't check it, but it took me quite a long time. In some termets it was possible to set this time, in Gold it is not possible?
As for the modulation indication, I have not noticed it yet, but I do everything from the emodul level, and maybe it does not show it there.
In tech, I have a screensaver set, but I will turn it off, maybe someday I will notice the% of yours, although on the other hand, if it does not work as it should, I do not know why I need it
Maybe you need to drill a hole for IT specialists from techa, or maybe from a termet?

After turning on the weather, a modulation icon appeared in my case
For now, only dashes without indicating the value, but maybe these will also appear over time
I wonder why, as you write, it shows once, sometimes not
After uploading the new software, the weather station works very well for me
It keeps the set temperature on the boiler and reacts to the set temperature on the room controller, i.e. turns off the heating after exceeding the set temperature, which was not so obvious before
For now, I am very happy with the purchase of both the boiler and the controller
The most exciting

remote control me from anywhere
Yesterday I was not at home all day, so I lowered my room set to 22 degrees
An hour before my return I turned 23 and when I got home it was 22.6
The boiler heats up slowly even by the 1st one, but with a 40st power supply it is obvious
However, the radiators were warm and the feeling of heat was very noticeable, even though it did not reach 23 degrees
What more could there be, let it continue
