   I think that there are two issues. First, you mention (I think) that 
if you set both the heating and cooling set point to zero then the 
component doesn't do anything. This is correct; when neither heating nor 
cooling is active then the fan coil turns off and just acts as a 
pass-through device (ie the air state and liquid state exiting the fan 
coil is the same as the air state and liquid state entering the coil).

   The fatal error that you are getting is because the data file that 
you are using for Type987 has got too many points in it for the size of 
one of the arrays inside the TRNSYS kernel to handle. You can do one of 
two things. You can simplify the data file so that there are not so many 
values of the independent variables (normalized fluid flow rate, 
normalized air flow rate, inlet fluid temperatures, inlet air dry bulb 
temperature, and inlet air wet bulb temperature) and therefore not so 
many lines in the data file. Or, if you are able, you can recompile the 
TRNDll with an increased value of the variable maxArraySize in 
readin.f90. The default (I believe) is 5000 spots which means that there 
are more than 5000 points in the Type987 data file currently.
Kind regards,
