Hello All,

I am trying to design a custom controller for the Low temperature heated floor in Energyplus with a controller designed in BCVTB. Currently, I am able to create a simple IDF file using the Underfloor Heating Example in Designbuilder and is able to read and send data to the IDF using the BCVTB in runtime.

Now, the HVAC system fr this example looks like the following

What I am hoping to do is that I want to control the water flow into the zone via a thermal actuator, simulating how the actual underfloor heating system looks, manifold with a thermal actuator.

Now the question is, How can I create an actuator with Schedule of ON/OFF on the input line that control the flow of water to the hot water into the zone?

Do I have to use the EnergyManagementSystem (EMS) for creating the actuator? and can I use ExternalInterface: Actuator to control it from BCVTB?
