ABSTRACT:
A method of selecting a ventilation control strategy from among a plurality of ventilation control strategies. The method comprises the steps of: determining if a CO2signal is present and valid; selecting a CO2based ventilation control strategy if the CO2signal is present and valid; selecting a second ventilation control strategy if the CO2signal is not present or is invalid; and operating using the selected strategy. The selection step occurs in a zone controller.
