Hello, I want to control 2 different zones in a residential building in Ottawa with energy plus. the whole building area is 120 m^2 and the Zone 1 Area is 104 m^2. My HVAC system has a cooling coil:DX: single speed and a Heating coil:fuel. The air loop HVAC that I have defined is Unitary:Furnace: HeatCool. I have defined different set points and setbacks for each zone at different times of the day in the schedule: compact. The thermostat control is Dualsetpoint and I have defined 2 thermostats (one for each zone). I have one supply fan and no return fan. I have defined a zone splitter, air terminal single duct, and a zone mixing air system. The problem is that when I run the system there are no errors and it says all nodes and branches and connections are correct but when I see the variables (Mean air temperature of each zone) it seems that there is no control on the zones and the HVAC system is not working. for example, the Indoor air temperature reaches below 10 C!
could you please guide me about the problem that would exist? How can I define a controller for a zone and set the setback and set points?
