### Real system simulation

I know how to simulate an autosizing simulation. For example, I leave link with Heat Pump' IDF, I get via autosize 12,2 kW, 2.57 m^3/h for heating, and 25,9 kW, 0.34 m^3/h for cooiling.

If I again simulate with 12000 W for heating, and 25000 W for cooling, I get this error:

** Severe ** Coil:Cooling:DX:SingleSpeed "PTHP COOLING COIL" -- coil bypass factor calculation did not converge after max iterations.
** ~~~ ** The RatedSHR of [1.000], entered by the user or autosized (see *.eio file),
** ~~~ ** may be causing this. The line defined by the coil rated inlet air conditions
** ~~~ ** (26.7C drybulb and 19.4C wetbulb) and the RatedSHR (i.e., slope of the line) must intersect
** ~~~ ** the saturation curve of the psychrometric chart. If the RatedSHR is too low, then this
** ~~~ ** intersection may not occur and the coil bypass factor calculation will not converge.
** ~~~ ** If autosizing the SHR, recheck the design supply air humidity ratio and design supply air
** ~~~ ** temperature values in the Sizing:System and Sizing:Zone objects. In general, the temperatures
** ~~~ ** and humidity ratios specified in these two objects should be the same for each system
** ~~~ ** and the zones that it serves.

I do not undertand why I get error if I use results from E+. I get similar mistake when I simulate real system in a real building.
