Error in unmixed air model

edit

Hello, I am making an Open Studio model and when I add the design days, I get the following error. Does anyone know how to solve it?

** Severe  ** DualSetPointWithDeadBand: Effective heating set-point higher than effective cooling set-point - increase deadband if using unmixed air model
**   ~~~   ** occurs in Zone=ZONA VIVIENDA During Warmup & Sizing, Environment=SANTANDER ANN CLG .4% CONDNS DB=>MWB, at Simulation time=08/21 00:00 - 00:15
