edit

Hi!! I am modeling a large building, this warning presented, please anyone could said me how fix it?

************* Beginning Plant Sizing Calculations
** Warning ** In calculating the design coil UA for Coil:Cooling:Water OS:COIL:COOLING:WATER 3
**   ~~~   ** the coil bypass factor is unrealistically large;
**   ~~~   ** The initial design conditions are: Tair,in = 32.1967
**   ~~~   **                                    Wair,in = 1.759751E-002
**   ~~~   **                                    Twater,in = 7.2200
**   ~~~   **                                    Tair,out = 12.8000
**   ~~~   **                                    Wair,out = 8.500000E-003
