The dialogs on the External Heat Exchanger, Auxiliary Heating, and DHW Standby Tanks can be accessed via the Components page.
On the Control page, the volume flow rate of the primary and secondary loop pump is either specified as relative to mean DHW consumption or entered as an absolute value in liters per hour.
The temperature in the heat exchanger can be limited to a maximum temperature via the mixing valve field.
Whether the pump in the primary loop is started up or stopped is controlled by the draw-off flow rate for DHW consumption.
For example, if you have defined 100 liters per day as hot water requirement in the DHW consumption section, the pump in the primary loop is activated on a draw-off flow rate of 10 liters per hour. Analogously, the pump is deactivated on a draw-off flow rate of less than 9 liters per hour.
If you select the ![Anti-Legionnaire’s Switch]
Anti-Legionnaire’s Switch checkbox, the Anti-Legionnaire’s page appears.
