| A special MFA controller delivers
                              a fully coordinated split-range adaptive temperature
                              control system. This MFA is able to manipulate damper,
                              heating, or cooling to tightly control supply air
                              (SA) temperature. Highly robust and adaptive, the
                              MFA can handle the control problems caused by changes
                              in operating modes, seasons, loads, and environment.
                              Once installed, no manual tuning is required. Standard
                              MFA can tightly control Mixed Air Temp, humidity,
                              flow, and pressure loops. | 
                            
                                
                                  | Using MFA, zone temperature can be tightly
                                    controlled even when there are large variations
                                    in load, coupling factors in multiple zones,
                                    process nonlinearity caused by wrong actuator
                                    sizing, changing seasons and environment. |

                                    control of all critical variables for semiconductor
                                    HVAC systems, clean rooms, pharmaceutical
                                    and industrial laboratories and any environment
                                    that must be stringently controlled. |

                            • Easy startup and elimination
                              of manual tuning of controllers saves technician
                              time and expense,  • Better control with
                              no oscillation yields energy savings,  •
                              Reduced wear and tear on actuators lengthens equipment
                              life,   • Tighter control increases user
                              comfort levels and allows Building Control suppliers
                              to address more stringent user demands, and
