<p>Dr Bina,</p>
<p> I would guess that the cause of the error is that the cooling
data file doesn't have the correct number of data values in it or
else that it does not exist where it is expected to be found. The
file is not accessed until it is needed so it makes sense that the
error would not appear until cooling is required in the building.
<br>
</p>
<p>In "supply air conditioning" you want to select "external by
another component" and then select "userdefined" for both the
temperature and the humidity. Define input variables for each of
these. When you save your changes in TRNBuild and return to the
Studio you will have three new inputs (mass flow rate,
temperature, and relative humidity) for the air that is going into
that zone of the building. These will be passed from the fan coil
model.</p>
<p>kind regards,</p>
<p> David</p>
