Viessmann 222f HO1C

Post by Mathieu144 »

Dear members,

I'm wondering if someone already setup a Netatmo smart Thermostat on a boiler Viessmann 222f with HO1C Regulation?
I take a look on netatmo check tool but without answer... also on a lot of forum.

thanks for your support.
Best regards
Mathieu

You can hook up a „dry-contact“ thermostat like the Netatmo Thermostat directly to the Viessmann 222f using the terminal „96“ according to manual.
The boiler will then heat up to a coded temperature.

How it will behave in combination with the H01C, I can‘t tell you.
