[EnergyPlus_Support] Autosizing problem with reheat coils

["Elmer Morrissey" <elmofuddly@xxxxxxxxx>]

Hello all,

I am having a lot of difficulty with an autosizing problem. I have a
relatively simple system that takes 100% FA which is heated to 16C by
a heating coil in the main AHU. However, the reheat coils are meant to
provide the remaining heat for the supply air. I would like everything
to be autosized.

The errors look like this...

   ** Warning ** The design coil load is zero for
COIL:Water:SimpleHeating RH:1
   **   ~~~   ** The autosize value for max water flow rate is zero
   **   ~~~   ** To change this, input a value for UA, change the
heating design day, or lower
   **   ~~~   **   the system heating design supply air temperature

However, I am happy with the design day and I do not want to lower the
system heating design supply air temperature any lower than 35C. Is it
possible to autosize both the UA and the flowrate?

I really appreciate it. I've uploaded the problem to the problem
submittals area with the file name... warmair.zip. 

Kind regards

-Elmer Morrissey
