Viessmann multiple zones

[parhs]

I know that through opentherm thermostats it is possible to control Vitodense 100-w DHW. But in case you use a simple thermostat there is no way to turn it off remotely.
In case of having multiple zones I can't find a way to control dhw since only one opentherm thermostat can be connected.
Is there a way to be able to control DHW and multiple zones at the same time?

Hot water prioritie box also sounds like a weather comp sensor would be best and just use standard thermostats inside

Have you phoned Viessmann to get there thoughts ?
