But my problem Is only at the start, because before it modulates, it's open valve gas at max for 1-2 secs.

I have an EcoTec Plus VMW 35KW During summer showers, the modulation required is around 13-15% The problem is that when turned on the boiler tends to "open" at max or almost for 1-2 seconds and then starts to modulate. But that max is enough to send the DHW temperature above 63°C (48°C...

D.009 is 50: it's the desidered flow temperature; instead D.005 value increases to get D.009 value I've read full "Vaillant vSmart - Any experts out there?" topic , but no replies answer to my question

My Vaillant Ecotec plus VMW 35 has this heating curve. (A is outside temperature and B is the hating flow temperature) I'm using it with VSmart remote control. I don't use advanced algorithm but the hysteresis one. This morning outside temperature was 16°C in according with the app. I've my...

So do you changed your vsmart? Or only some parameters?

I'm using and testing this system from about 15 days. On my radiators I've classical thermostatic valve and never changed setup in this 15 days. (Most of them are on position n°3) Starting the system when room temperature is 19.7° C (VSmart placed in the coldest room, setpoint 20.0 °C, heating...
