Agreed, it would help solve the issue to see the project at-hand.

That said, you *should* be able to generate a variety of air-cooled
heatpump system configuratinos using the DD wizards.  It might prove
helpful to quickly create a separate simple project in that manner,
befitting your actual system, to compare wizard-generated inputs against
your current project.

I suggest posting your .inp and .pd2 file to the egroup. Someone will look
at it to determine what might be incorrect.

Dear eQuest users

Recently, I got a problem when I try to simulate an air-cooled heat pump.
Since we cannot choose air-cooled heat pump under wizard mode, I try to set
it under detailed mode. What I have done:

1. Switch the default 'chilled water loop' to '2-pipe loop';

2. Switch the chiller type to 'heat pump';

3. Switch the HW loop to 'chilled water loop' in air-side system;

However, when I try to switch the condenser type to 'air cooled', an error
is shown like 'assigned symbol air-cooled is of an incompatible type'. Does
anyone be confused by this situation? I guess someone may have solution for
