2.3.If the user desires any simulation that uses weather filedata, the number of RUN-PERIOD intervals must be greaterthan the number of DESIGN-DAY instructions.A PLANT run is possible only if the number of RUN-PERIODintervals is greater than the number of DESIGN-DAYinstructions.4. Up to 3 DESIGN-DAY instructions can be entered. If morethan one DESIGN-DAY instruction is entered, the instructionsmust be entered in chronological order.5. Although weather conditions are not affected by holidays andweekends, internal building loads may be affected.Therefore, when choosing a DESIGN-DAY, especially if it issmall, the user should be aware of the presence of holidaysand weekends that fall within the interval.6. If DRYBULB-HI = DRYBULB-LO or if DEWPT-HI = DEWPT-LO, theprogram will simulate a constant temperature throughout theday.7. If DRYBULB-HI * DRYBULB-LO, do not set HOUR-HI = HOUR-LO.If DEWPT-HI * DEWPT-LO, do not set DHOUR-HI = DHOUR-LO.Ex amp le:A typical summer design day for Los Alamos, New Mexico, would beentered (note that the dew-point temperature frequently variesopposite to the dry-bulb temperature.):= DES IGN-DAYDR YBULB-HIDRYBULB-LOHOUR-HIHOUR-LODEWPT -HIDEWPT-LODHOUR-HIDHOUR-LOWIND-SPEEDWINO-OIRCLOUD-AMOUNTCLEARNESSGROUND-TCLOUD-TYPESU~IMER= 88.56.15565.::::: 65.= 5= 15= 5.= 1551.15= 50.= 0II 1. 28 (Revised 5/81)
