Could you please tell me how I could define 'Field HTF min operating temp' and 'Field HTF max operating temp'? Because when I try to simulate using an user-defined HTF I always have a warning like this: "trnsys.dtr: WARNING: The temperature for User-specified fluid was outside of the fluid's operating range of -273.- 320. [C] for at least 50 time steps. The fluid temperature on the 50th occurrence was -97.5 [C] at timestep 1.0. Try changing the design parameters or fluid to ensure operating temperatures stay within the range" and I would like to know how to avoid it.
Thanks in advance,
Acerina
