- I have a Vitodens 333 heating system with LAN-Module no WLAN. My heater installation company replace my old one. I had perfect connections with the new lan-module. Now I changed my mobile phone and now when I try to register the lan- module I receive the message this module is already registered. My Hersteller Daten: 7555115615633100. I am using the ViCare app. Please advise how I can connect the lan-module so I can use my ViCare app. Thank you advance for your quick reply.
