Hello everyone,
I'm getting this severe error in my model:
** Severe ** DualSetPointWithDeadBand: Unanticipated combination of heating and cooling loads - report to EnergyPlus Development Team
** ~~~ ** occurs in Zone=THERMALZONE_F1_BATH1 During Warmup & Sizing, Environment=FRANKFURT AM MAIN 1, at Simulation time=07/21 00:00 - 01:00
** ~~~ ** LoadToHeatingSetPoint=NAN, LoadToCoolingSetPoint=NAN
** ~~~ ** Zone Heating Set-point=0.00
** ~~~ ** Zone Cooling Set-point=0.00
** ~~~ ** Zone TempDepZnLd=
** ~~~ ** Zone TempIndZnLd=
** ~~~ ** Zone ThermostatSetPoint=0.00
I know this error was discussed multiple times (e.g. here) but none of the mentioned ideas let me pinpoint the issue.
- I tried ReportDuringWarmup and ReportDuringHVACSizingSimulation but it seems to fail before any of those are even run.
- The zone appears geometrically correct and only has one window opening.
- No other errors or warnings indicate a problem that might be relevant.
- All heating schedules data in the IDF ouput looks valid and is set to be 23°C all year for that specific zone.
I'm honestly out of ideas.
The models .osm can be found here and I'd be glad if anyone could take a look.
Thanks in advance
