Thank you for answering but is there a way to do it directly with designbuilder without exporting to energyplus.

if i try using the Ems file for my case Schedule:Constant,Cycle,OnOff,1; ! New schedule object

BeginTimestepBeforePredictor, HVAC_uncontolledloop_Supervision; EnergyManagementSystem:Program, HVAC_uncontolledloop_Supervision, SET Toffset = 1.00, IF AptTemp > (hSP - 0.01) && AptTemp < (hSP + 0.01), SET AvailSCH_Overwrite = 0, ELSEIF AvailSCH_Overwrite == 0 && AptTemp >= (hSP - Toffset) && AptTemp <= (hSP + Toffset), SET AvailSCH_Overwrite = 0, ELSE, SET AvailSCH_Overwrite = 1, ENDIF;

I think DesignBuilder has EMS module (although in Beta version) link

Regarding the severe error I am not sure I can help just by seeing your code. You can switch on EMS outputs to check what your code does at each timestep.
