Hi @Eric Ringold. I still didn't manage to make it work. I tried using a Trend Variable as follows. EnergyManagementSys

I'm using EMS to set the window operation (open = 1, closed = 0) according to the zone CO2 levels (over 800 ppm the window should open). It's working fine but the problem is that the window state changes each timestep (reaches the target - window opens / the next timestep is below the target - window closes... and so on). Any suggestions on how I could overcome this oscillation?

My code is:

EnergyManagementSystem:Sensor,
  Num_People,
  Ocupacao_Z1,
  People Occupant Count;

EnergyManagementSystem:Sensor,
  Sensor_CO2,
  Z1,
  Zone Air CO2 Concentration;

EnergyManagementSystem:Actuator,
  Window,
  Window,
  Schedule:Constant,
  Schedule Value;

EnergyManagementSystem:Program,
  CO2_window_control,
  IF (Num_People > 0) && (Sensor_CO2 >= 800),
  SET Window = 1,
  ELSE,
  SET Window = 0,
  ENDIF;

Thank you.

Hi @Eric Ringold. I just tried to use a fixed value for the deadband but the oscillation continues. I would have to inc

Hi @Eric Ringold. Sorry, but I'm not being able to find out how I could set the deadband. Could you help me, please?

Sorry, I received an error and I thought this one wasn't posted, so I posted it again. I'll erase this one.

Hi Eric. That will solve my problem, thanks so much for your help!

Hi Aaron. I want the window opening actuator to stop oscillating. I think Eric's suggestion of adding a deadband will so
