This keyword is used to describe a shunt valve.
FORMAT:
*SHNT <Nodeid, Tshnt> /
Nodeid : node identification (-)
Tshnt : Required temperature
Note that if the node is provided with a shunt valve device, no other devices are permitted in the node (e.g. a bypass).
As there is a node reference under the *SHNT keyword, this must be specified after the *NODE keyword.
Even a requested supply pipe temperature cannot always be obtained. If e.g. Tshnt = 100°C and max. temperature in the network is 90°C. In these cases, a warning is issued.
