copy the 2 schedules (cooling and heating set point temperatures) from your input file into the email so we can see them

I did not make any changes in the heating setpoint schedule. I just increased the cooling setpoint schedule. So all the cooling setpoints in my new schedule are higher than the heating setpoints still it is giving me this error message,
"DualSetPointWithDeadBand: Effective heating set-point higher than effective cooling set-point".
 
Please help.
 
Thanks,

You increased the heating set point above the cooling set point. The cooling set point must be higher than the heating set point. Raise both temperatures.

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
