Patent ID: 8467905

Claim:
A control system for governing temperature levels within a confined space having a heating system, a cooling system, and a thermostat controller operatively coupled to the heating system and the cooling system, the control system comprising: a first sensor adapted to detect internal temperatures within the confined space; a second sensor adapted to detect external temperatures external to the confined space; a controller coupled to the first and second sensors, and having an input adapted to receive a plurality of settings including a first high temperature tolerance setting and a first low temperature tolerance setting, the controller being adapted to compare the internal temperatures, the external temperatures, and the plurality of settings to a plurality of predefined rules for governing a generation of commands by the controller; and an external air intake operatively coupled to the controller and adapted to introduce air from outside the confined space into the confined space; wherein the controller generates commands for operating the external air intake to bring in external air if: (1) the internal temperature is greater than the first high temperature tolerance setting or lower than the first low temperature tolerance setting and (2) the external temperature is less than the first high temperature tolerance setting and greater than the first lower temperature tolerance setting.
