Opentherm, flow temperature and weather adaptation.
I’ve just had my boiler replaced with a Vitodens 100 Combi. I have an existing Tado setup with SRV throughout. It was connected to the old boiler in switch mode. I’ve connected to the Vitodens via Opentherm.
My questions boils down to how much control does Tado have over the boiler via Opentherm, and what takes precedence, the boiler or Tado?
- Can Tado change the flow temperature? I see it changing, but what is controlling it?
- If it can, does this mean Tado weather adaption does this, thus rendering Viessmann’s own weather compensation unnecessary?
- If I did fit Viessmann weather comp, which takes precedence?
One more thing. A Hot Water control has appeared recently, this doesn't affect DHW temp for me, I guess it’s aimed at system boilers. Can it be removed from the app?
