For sizing runs in EnergyPlus/OpenStudio, is it possible to have a winter design day temperature setpoint above the summer design day temperature setpoint? It's not atypical to size certain zones to heat to the maximum temperature and cool to the minimum temperature to ensure any temperature within the range can be achieved.
I tried this in OpenStudio and received the following error...
Severe ** DualSetPointWithDeadBand: Effective heating set-point higher than effective cooling set-point - increase deadband if using unmixed air model
My heating thermostat schedule has a winter design day temperature of 75F and my cooling thermostat schedule has a summer design day temperature of 70F. The default profiles are 70F for heating and 75F for cooling.
