DualSetPointWithDeadBand: Unanticipated combination of heating and cooling loads

Postby vosiman » Mon Apr 01, 2019 7:58 am

Hi everybody,
my building is a big office building with open spaces. They are served by induction units, two AHUs and Heat pumps with ground exchangers. I have this problem:

** Severe ** DualSetPointWithDeadBand: Unanticipated combination of heating and cooling loads - report to EnergyPlus Development Team
** ~~~ ** occurs in Zone=B3X5NP:OFFICE Environment=RIVER CITY_KARLIN (01-01:31-12), at Simulation time=02/15 14:15 - 14:18
** ~~~ ** LoadToHeatingSetPoint=NAN, LoadToCoolingSetPoint=NAN
** ~~~ ** Zone Heating Set-point=22.00
** ~~~ ** Zone Cooling Set-point=24.00
** ~~~ ** Zone TempDepZnLd=NAN
** ~~~ ** Zone TempIndZnLd=NAN
** ~~~ ** Zone ThermostatSetPoint=0.00
** Fatal ** Program terminates due to above conditions.
...Summary of Errors that led to program termination:
..... Reference severe error count=1
..... Last severe error=DualSetPointWithDeadBand: Unanticipated combination of heating and cooling loads - report to EnergyPlus Development Team

Can you help me with that please? I don't really know what to do :-( there is no chance how to set two induction units in the same zone. One for cooling and one for heating. I don´t know what TempDepZnLd and TempIndZnLd mean. NAN is not a number.
Thank you,
Vojtech Siman
