Suggested CO Control Sequence Of Operation

2 Control Sequence Of Operation Installation Coverage: One sensor should be used for each zone of major occupancy or per air handling device if a number of devices serve a large zone. If occupancy density/patterns/usage are different in two adjacent areas each area should be considered a separate zone. Generally one sensor can serve up to 5,000 sq feet. Larger coverage is possible in theaters ...
