Hi! I'm modeling my single zone building using OpenStudio. I'm having a problem with my HVAC system because sometimes the heating and the cooling coil are working at the same time. image description

In this example the cooling system starts and then stops for a little time, and the interior temperature is very far from the cooling setpoint. The AVAC template I added to my model is a Packaged Rooftop Heat Pump. image description

I had an identical problem some weeks ago and I asked here in unmethours. At the time @rraustad suggested me to had another setpoint manager. Until the moment I didn't find how to add a setpoint manager in OpenStudio and I'm a little bit lost in this situation. Can you please explain me how to add a setpoint manager in my HVAC model? How can I solve this problem? Here is my model. Thank you

Hi Wilson, I also have a similar problem, on my case is with the radiant floors systems. So your question will help me as well

I'm sure someone can add a bit more detail to my answer. When you are in the HVAC module, go to your library, scroll down until you see the S's and you will see a list of setpoint options. Click the arrow on the left to bring up the setpoint manager. Add the setpoint manager you wish to place in the node that you want to place it in (like any other piece of equipment).

Thank you for your answer buddy1187! I'm trying to add the "Setpoint Manager One Stage Cooling"(I don't know if is this the right one) but with no success. I tryed to place this setpoint manager in every single nodes to test the AVAC behavior but the system does not maintain between the heating and cooling setpoint limits. Some help is needed. I don't have knowledge on HVAC design and to progress in my modeling my building I need to find the solution for this problem. What is the Setpoint Manager I need to use and in which node I have to add it? Thank you
