The primary problem here is that these zone thermostat actuators have no impact until the next call to the Predictor:
EnergyManagementSystem:Actuator, FC2_4_HEATSET, !- Name Office 1121, !- Actuated Component Unique Name Zone Temperature Control,!- Actuated Component Type Heating Setpoint; !- Actuated Component Control Type
So, any EMS program that sets these should use calling point BeginTimestepBeforePredictor. That's why there's a lag happening here
