Hi there,
I have a VAILLANT EcoTec Plus VUI 246/5-5 (H-INT II) that I control with vSmart app.
The boiler reacts heats water per schedule, reacts to commands from the app - I just switched off the summer mode (as in no heating) and the summer mode icon disappeared.
The problem is that the boiler doesn't react to temperature changes. The app's front page does display the desired temperature - but that detail misses from the heating graphs. In fact, it disappeared from the history altogether.
The apps shows that the boiler is operational but it's not. I restarted the relay, the thermostat, turned the boiler off and on. No change.
I'm at my wits end.
Any advise appreciated.
