Example of one building with one thermal zone in which the room air temperature is controlled with a PI controller. Heating is provided through recirculated air. The control output is used to compute the set point for the supply air temperature, which is met by the heating coil. The setpoint for the room air temperature changes between day and night. The fan is either off, or operating on stage 1 or 2, depending on the output of the room temperature controller. The zone also has a constant air infiltration flow rate.
Note that for simplicity, the model has no cooling system. Therefore, in summer, the house overheats.
