[Vlad1]

Hi, I have Vitodens 200-W (7424978202703102) with Vitronic 200 H01B, weather dependent. and VITOCOM 100 Lan1

How to set up automatic time synchronization via the Internet after a power outage? In general, it is possible to do this automatically through vitocom 100 lan1?

Then Check Code 81.

To  receive the time it must be set to 81:3
