Abstract:
1. An air control system for controlling both vent air and combustion air, comprising: a pressure sensor, wherein said pressure sensor detects an environmental pressure characteristic of an enclosed environment and wherein said pressure sensor produces a signal representative of the detected environmental characteristic; a single controller, wherein said single controller receives said signal and wherein said single controller utilizes said signal to determine if the detected environmental pressure characteristic is within a desired operating range, and wherein upon said detected environmental pressure characteristic being outside said desired operating range said single controller produces both a first output signal and a second output signal; a vent air actuator, wherein said vent air actuator receives said first output signal from said single controller and responds thereto by operating to adjust said environmental pressure characteristic in pursuit of said desired operating range; and a combustion air actuator, wherein said combustion air actuator receives said second output signal from said single controller and responds thereto by operating to adjust said environmental pressure characteristic in pursuit of said desired operating range.
