Hello, I have installed a Viessmann VitoDens 200-W B2KB-26 boiler with climate control and Tado system for modulation and remote control. I decided to add a solar panel for the production and storage of domestic hot water. Not having much space available near the boiler, I am forced to install a panel with integrated boiler and natural circulation (Vitosol 111-F).
In the little space available near the boiler I would like to install a second 60/80 liter domestic water boiler to be heated by the boiler when the water in the solar panel boiler is at low temperature and through the recirculation of the hot water present in the solar panel when this is hot.
I thought of using the additional SM1 module by connecting:
- the recirculation pump to terminal 22
- the storage tank temperature probe on the solar panel at terminal 7
- the temperature probe of the second storage tank on terminal 10.
A solution like this can work by setting all parameters directly on the VitoDens 200-W boiler.
Thanks in advance
