[EnergyPlus_Support] Coil Autosizing Problem

["energypluser" <energypluser@xxxxxxxxxxxx>]

Dear all

I configurate a heating coil for a fan coil system. But when I do the 
design day simulation for autosizing. These messages show up. And I 
have changed the UA value, the heating design day data amd the supply 
air temp. But the messages still there.
Please help me
Thank you in advance

   **   ~~~   ** To change this, input a value for UA, change the 
heating design day, or lower
   **   ~~~   **   the system heating design supply air temperature
