5.4.4 Settings for DHW circulation
A DHW circulation pump circulates DHW between the DHW
heater and the draw-off point (e.g. water tap). This makes DHW
available at the draw-off point more quickly. Settings can be
made determining when and how often the DHW circulation
pump is activated.
This menu is only available for systems with DHW circulation
pump.
