Questions about Vaillant eloBLOCK VE14/14 EU I - 400V, 14 KW elkedel

Unfortunately, I don't understand your question.

I'm not completely certain about the compatibility of the Vaillant boiler with the Netatmo thermostat. The information I have does not fully address this situation. Generally, Netatmo thermostats are compatible with many boilers, but specific compatibility can depend on the boiler's features and communication protocols. For precise compatibility, I recommend checking Netatmo's official compatibility tool or contacting their support directly.
