No suitable KVS value found
The error message
This error occurs when Hysopt is unable to select a 2 or 3-way valve, because the calculated volume flow/pressure drop is out of range of a suitable selection. In the example above, you can see that the filled in capacity is 1W at 70/50°C, which calculates a nearly zero m³/hr flow. This was meant to be 1kW but is filled in incorrectly. Hysopt is unable to calculate a valve and hence sends this error message.
