Viessman Vitodens and V3 thermostat boiler issue
I have a Viessman 100-W B1HF-M and a V3 Tado setup
The bridge, hub and thermostat are all connected to the WiFi
However when adjusting settings via the app or using the thermostat it doesn’t ‘call’ the boiler
Link below is to an image of the current wiring. How do I fix this?
