Hi All,
I'm modeling a health care facility and the HVAC system is GSHP. Each time that I run the model, it gives me warning about the following errors:

Ground-loop HX: GLHX (VertWell-CM)

is undersized for the load and is producing an extreme

temperature of -388F. Mon/Day/Hr: 1/ 1/ 1

OR

Ground-loop HX: GLHX (VertWell-CM)

is undersized for the load and is producing an extreme

temperature of 351F. Mon/Day/Hr: 1/ 1/ 1

Anybody has any ideas what's the reason for these extreme temperatures?

Thanks in advance.
