Suggested CO Control Sequence Of Operation

offices can generally be controlled with one sensor in the central space (up to 5000 sq ft). In office building floor plates divided up into separate suites, at least one sensor per suite is recommended. Sensor Placement: Sensors should be placed so that they can take a representative sample of CO 2 concentrations in each major occupied zone. Sensors can be placed in the space using similar ...
