General User Input Values Physics Used Displays Example
A heat flow is coupled out via connection 3.
This heat flow can, for example, also be specified with control elements (component 12, 39, 69: controller with internal or external values) (FT = 0).
Alternatively (FT= 1, FT = -1), the temperature at output T2 can also be specified.
In the cases FT=1 and FT=-1, the delivered or required heat quantity is applied as enthalpy to the logic line.
Since negative values are permissible on this logic line at connection 3, the heat extraction can also be used as heat input.

Temperature setting for outlet temperature T2 =0: T2 Calculated from heat balance =1: T2 given by the value of T2SET =-1: T2 preset from outside (via the line at port 2) |
| T2SET | Outlet temperature T2 in case FT=1 |

The parameters marked in blue are reference quantities for the off-design mode. The actual off-design values refer to these quantities in the equations used.
