[TRNSYS-users] Type 534 - Problems with input values

[Heikkilä Marko]

Dear TRNSYS users,

I`m creating a ground source heat pump system with Type 534 - Cylindrical Storage Tank with Immersed Heat Exchangers. In that type I need at least heat exchanger connected to heat pump. A second one might be needed for the connection with floor heating, because the domestic heat water might be taken into account too as with paired inlet/outlet port.

Setting the input values for that type is a bit confusing. I found a previous mail sent to the list, where was told that every value should be set with period (because of the american standard), although every decimal number in the plug-in is typed with comma. After I`ve changed all the values needed with period and pressed OK, almost every value has been changed when I open the plug-in next time. It seems that set decimal values have been separated and the latter half of the number has jumped to another row. One way to prevent this is to set up the desired values to the data file created manually, but in that case you should be aware about the configuration about the system, because the number of rows depends on the chosen structure of the storage tank. However, this way is quite complicated and risky. I really would appreciate, if anyone could give me an advice how to set the values via  plug-in without changing.
