Vaillant SensoNET (API)

← Heating

The boost function heats hot water or a boost zone. The boost zone is identified by the ID. The boost temperature is specified in degrees Celsius. If boost temperature is specified, the boost zone is activated, otherwise hot water. Note, if the appliance's DHW operation mode is set to "off" so that evcc fully controls hot water, the appliance no longer runs its weekly legionella protection. Make sure to periodically heat the water to disinfection temperature yourself (e.g. via time program or a forced boost).
