Via EMS, I want to adjust the fan air flow at some moments. I know how to adjust it. However, I can't figure out how to get it back to the orginal speed after the moments of fan increase via the ems. For simplification, I now have this.
EnergyManagementSystem:Actuator,
FANN,
5 ZONE PVAV FAN,
fan,
Fan Air Mass Flow Rate
EnergyManagementSystem:Program,
Fanprogram
IF (DayOfWeek ==2),
SET FANN=15,
ENDIF;
For this example, I want to increase the fan flow rate to 15 kg/s every 2nd day of the week. After the 2nd, day I want to revert it back to the speed what it would normally do. However, now it stays on 15 kg/s forever. I want it to go back to the default value after the 2nd day is finished. And this default value varies over time (depending on heating/cooling load), so it is not a constant value.
I hope someone can help.
