The indoor air quality is controlled by the
Touch Pilot
control via the input from the CO
2
sensor, adjusting the
economizer. Please refer to the Touch Pilot IOM for the
control logic. The room air CO
2
sensor, together with the
connector, is in the control box. Please refer to the wiring
diagrams for the required connection and correct cable
diameter selection criteria. Sensor locations vary with

When a large amount of fresh air is introduced into the
zone, power exhaust fans can be used to exhaust excessive
air.
The exhaust fan runs when the outside air dampers are at
least 50% open (adjustable value). It is overload protected.
