Hi All,
I am working on a DOE prototype building(medium office). I created a new cooling set point schedule and assigned it at Thermostatsetpoint:DualSetpoint. In the new schedule I have just increased the set point temperature in stepped pattern by total 3.3 deg. C for 3 peak hous for a peak summer day. Remaining schedule is not changed. I am running this simulation for just that peak day. But after this change I got a severe error and my simulation terminated. The error is:
-------
** Severe ** DualSetPointWithDeadBand: Effective heating set-point higher than effective cooling set-point - increase deadband if using unmixed air model
** ~~~ ** occurs in Zone=CORE_BOTTOM During Warmup, Environment=Phoenix Sky Harbor Intl Ap AZ USA TMY3 WMO#=722780, at Simulation time=06/28 00:00 - 00:10
** ~~~ ** LoadToHeatingSetPoint=-41431.055, LoadToCoolingSetPoint=-125592.948
** ~~~ ** Zone TempDepZnLd=429.02
** ~~~ ** Zone TempIndZnLd=11375.49
** ~~~ ** Zone ThermostatSetPoint=0.00
** ~~~ ** Zone HeatingSetPointOffset=0.00
** ~~~ ** Zone CoolingSetPointOffset=0.00
** Fatal ** Program terminates due to above conditions.

Can somebody please explain me where did I go wrong?
Thanks,
Amruta
