Hi just have fitted eco block of the 28 kw but wonder of el connection there is several slot for mono connection and three face if you can provide more details did i need both cable or possible from three face split one
The electrical connection for the Vaillant eloBLOCK VE 14 EU I Series should be configured as 3x230V/400V+N+PE, 50Hz. It does not require both mono-phase and three-phase cables; it is designed for three-phase connection only.
