Hey, All, I try to overwrite the zone_supply_air_temp and zone_supply_air_humidity, through the actuator on BCVTB/EMS combination. I can only reset the zone_supply_air_flow by a actuator successfully. I tried the actuators available from .edd file: "System Node Setpoint,Temperature Setpoint,[C] " and " System Node Setpoint,Humidity Ratio Setpoint,[kgWater/kgDryAir] ". All those actuators are related. But somehow they did not overwrite successfully. I am sure i made no mistakes on EnergyPlus inputs. Any help on that? Thanks!
