Functions available in ViCare are depending on functions available on boiler itself.

Works fine for me.

The user interface isn’t super intuitive, but I have found it useful and usable.

I have successfully used holiday mode for DHW and I liked that.

I had one odd issue today. We noticed the Hot Water temperature was low. I investigated to see if I could figure it out without calling the HVAC company. After checking a few things, I finally discovered the DHW Time Program. In there I discovered the entry for Monday was “Off” and all other days were fine. I have never used this and don’t recall ever seeing it before. I have no idea how Monday got turned off.

This and the other apps that Viessmann producers are less then desirable. I have a new Gas Vitodens 343 and Vitoconnect 100 and on a given day the thing does not work. Problem ONE is that constantly drops the signal and you have to go to the heater to change the settings. Problem TWO is the app kick you and requires you to login again only to tell you it can’t login you at which point you create a new account and it tells you that the info you are entering is not valid. I will stop here since there is limited space for an evaluation .... The short DON’T buy Viessmann because the product does not work....service NONE. If they only spend less on the cross country ski advertising and a bit more on the product that might be a start.


Works well

App works well, easy to use and install. Would be great if there was a way to integrate it into a home control system Iike control4 or Apple's HomeKit.

It also be nice if you could set a date/time when vacation or party modes were done so that boiler would go back to its normal schedule (just got home from vacation and it took a while to remember I had made the change before we left - the family was complaining that they had no hot water)....
