Re: [EnergyPlus_Support] DX Fan coil - Temperature (high) out of bounds

Add infiltration to get it to run and then look into why the gains are high.

I model a building that has a IT room with just DX coil in it with no fresh air. I used a single speed DX coil with coil heating gas and AirloopHVAC:Unitary:Furnace component. When I run the model, I have one sever error as follows:

** Severe  ** Temperature (high) out of bounds (202.62] for zone="02-05IT", for surface="383F89"
   **   ~~~   **  During Warmup, Environment=RUN, at Simulation time=01/01 11:30 - 11:45
   **   ~~~   ** Zone="02-05IT", Diagnostic Details:
   **   ~~~   ** ...Internal Heat Gain [0.000] W/m2
   **   ~~~   ** ...Infiltration/Ventilation [0.000] m3/s
   **   ~~~   ** ...Mixing/Cross Mixing [0.000] m3/s
   **   ~~~   ** ...Zone is part of HVAC controlled system.

I checked the surface and it's a surface adjacent to the corridor. The corridor is not conditioned, however, I do not know why the temperature on this particular surface is so high that it stops my simulation.

Can you please let me know about any tips/tricks that I overcome this problem?
