A single controller interface (Smart-Stat) integrates the control of heating or cooling in buildings by simultaneously controlling Heating, Ventilation and Air Conditioning (HVAC) systems in concert with separate fresh air ventilation (FAV) systems. The Smart-Stat reduces costs and the carbon footprint of typical HVAC systems by optimizing the use of FAV. User-programmable set-points are incorporated with time-of-day and day-of-week as well as data from multiple sensors, thermostats and weather information. Mathematical algorithms are used to determine control signals to the HVAC or FAV systems. The Smart-Stat integrates the two separate systems into a single system that is able to direct the call for cooling or heating to the HVAC or FAV systems, depending on appropriate outside weather conditions. Any building can replace its existing HVAC system controller with the Smart-Stat controller and incorporate a FAV system to create a single integrated HVAC and FAV system.
