Abstract
A method of air conditioning an environment with an HVAC system. The method comprises the steps of: determining an environment to be either occupied or vacant; determining a mode of operation for the HVAC system to be heating or cooling; determining a heating setpoint and a cooling setpoint; and determining a setback value equal to a difference between the value of the heating setpoint and the value of the cooling setpoint. The method also includes the steps of: establishing an operational setpoint equal to the heating setpoint if the mode of operation in the environment is heating and the environment is occupied; establishing an operational setpoint equal to the heating setpoint minus the setback value if the mode of operation is heating and the environment is unoccupied; establishing an operational setpoint equal to the cooling setpoint if the mode of operation is cooling and the environment is occupied; establishing an operational setpoint equal to the cooling setpoint plus the setback value if the mode of operation is cooling and the environment is unoccupied; and conditioning the environment in accordance with the operational setpoint.
