  • Publication number: 20150153056
    Abstract: A control method is for controlling a variable-speed direct gas-fired air-handling unit of a heating, ventilation and air conditioning system. The method includes sensing a make-up temperature of the system and comparing the sensed make-up air temperature to a make-up air temperature setpoint. If the sensed make-up air temperature is above the make-up air temperature setpoint, increasing the minimum make-up airflow. If the sensed make-up air temperature is not above the temperature setpoint, decreasing the minimum make-up airflow. If a burner gas valve outflow and burner enabling signal are accessible, there may be selective variation of the gas valve outflow, the burner status and the minimum make-up airflow.
