Variant menu: System Definition > DHW Supply
System Definition > DHW Supply or system schematic
The dialogs on the External Heat Exchanger and DHW Standby Tank can be accessed via the System Definition > DHW Supply > Components page.
On the Control page, the time it takes for the DHW standby tank to fully load is shown under Load Time . If the volumetric flow rate of the loading pumps is to be calculated from this value (i.e. the relevant radio button is selected), the load time can be modified.
Alternatively, you can also enter the required volumetric flow rate of the primary and secondary loops directly. The supply temperature in the primary loop can be limited to the required temperature in the DHW standby tank to prevent calcification via the mixing valve field.
The Speed Controlled Pump option in the secondary loop means that the volumetric flow rate of the pump is controlled in this way to reach the target temperature. You can set a fixed value for this target temperature. Click Accept to apply the respective desired tank temperature as the target temperature. This is recommended if you set different desired tank temperatures during operating times on account of the anti-Legionnaire’s switch.
If you select the
Anti-Legionnaire’s Switch checkbox, the Anti-Legionnaire’s Switch tab is activated.
