The present invention is related to the field of heating, ventilation and air conditioning (HVAC). More particularly, the present invention is related to methods and systems for controlled heating and cooling in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The present invention is directed to mathematical algorithms incorporated into a controller and a method of determining control signals that are dependent on said mathematical algorithms and user programming that integrates information from multiple sensors, thermostats as well as weather information. Used in any home or building, the controller controls heating, cooling and ventilation systems in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The controller works with typical HVAC systems generally in buildings and homes. The Smart-Stat algorithms are programmed into the controller and enable the controller to identify user-determined set-points alongside data from one or multiple internal temperature sensors. The user-determined set-points are also linked to time of day and day of week in a manner typical for typical thermostat devices available today. In such typical thermostat devices the controller will call for cooling or heating depending on the set points and conditions determined by the sensors in the building. The present invention is capable of interrupting the call for cooling or heating depending on whether the mathematical algorithms identify suitable outside weather conditions that permit the use of outside air cooling or outside air heating. Thus the call for heating or cooling can be redirected to call for ventilation instead of heating or cooling.

A controlled cooking system (CCS) that monitors, measures, and controls the internal temperature of foods placed in an oven having a Radio Frequency Identification (RFID) antenna(s), a transmitter/receiver/interrogator/reader/microprocessor (TRIRM) module and an RFID tag with built-in temperature sensor. The RFID tag is buried in the food being cooked and is energized and enabled by an RF signal of pre-determined frequency. The tag output is an RF “backscatter signal” having encoded temperature data indicative of the internal temperature of the food that the tag is buried in. The backscatter signal is received and decoded by the antenna(s) and the TRIRM module incorporating a programmed cooking/baking temperatures for various foods. If the decoded temperature is below a user-set temperature, the TRIRM module allows the oven to remain on. Conversely, if the decoded temperature is at or exceeds the user-set temperature, the TRIRM module shuts off the oven and produces a signal that activates an alarm indicating that the cooking has been terminated.
