Abstract
Upon detection of a high carbon monoxide condition, an intelligent thermostat regulates operation of appliances that have sources of combustion which could be the source of or may exacerbate the high carbon monoxide condition. This hazardous condition is detected by a detector and communicated to the intelligent thermostat by wired or wireless communications. The intelligent thermostat then communicates with these appliances either via wired or wireless communications. The intelligent thermostat may also operate a ventilation system to flush the environment with fresh air to minimize or eliminate the hazardous condition. External and internal temperature sensors allow coordinated operation of the ventilating and heating systems to flush the environment with fresh air without causing a freezing condition to exist within the environment.
