A climate control system for an animal house, the climate control system comprising: a plurality of climate control input devices configured to measure a climate input selected from the group of temperature and static pressure, wherein the plurality of input devices are for being located in different portions of the animal house; a plurality of climate control ventilation fans; at least one air inlet used to control airflow into the animal house, the at least one air inlet having a baffle configured to change the area of the opening of the air inlet to vary the amount of air coming into the animal building; at least one actuator operably connected to the baffle of the at least one air inlet having a motor, the at least one actuator configured for selectively controllling the position of the baffle; an open limit switch configured to be triggered when the baffle reaches a fully open position; a closed limit switch configured to be triggered when the baffle reaches a fully closed position; a sensor configured to read the current applied to the motor; and a control unit (27, 28) configured to receive input information from the plurality of climate control input devices and regulate the operation of the ventilating fans, characterized in that; the control unit is configured to control operation of the actuator using calibrated timed position opening and closing commands to adjust the position of the baffle of the at least one air inlet, the control unit further configured to account for dragging delays and overshoot inertias at calibration and consider these dragging delays or inertias in the calibrated timed position opening and closing commands; said dragging delays and overshoot inertias being measured as the amount of time the baffle continues to move after the control unit has given a command to stop. a plurality of climate control input devices configured to measure a climate input selected from the group of temperature and static pressure, wherein the plurality of input devices are for being located in different portions of the animal house; a plurality of climate control ventilation fans; at least one air inlet used to control airflow into the animal house, the at least one air inlet having a baffle configured to change the area of the opening of the air inlet to vary the amount of air coming into the animal building; at least one actuator operably connected to the baffle of the at least one air inlet having a motor, the at least one actuator configured for selectively controllling the position of the baffle; an open limit switch configured to be triggered when the baffle reaches a fully open position; a closed limit switch configured to be triggered when the baffle reaches a fully closed position; a sensor configured to read the current applied to the motor; and a control unit (27, 28) configured to receive input information from the plurality of climate control input devices and regulate the operation of the ventilating fans, characterized in that; the control unit is configured to control operation of the actuator using calibrated timed position opening and closing commands to adjust the position of the baffle of the at least one air inlet, the control unit further configured to account for dragging delays and overshoot inertias at calibration and consider these dragging delays or inertias in the calibrated timed position opening and closing commands; said dragging delays and overshoot inertias being measured as the amount of time the baffle continues to move after the control unit has given a command to stop.
