sensor, adjusting the
economizer. Please refer to the Touch Pilot IOM for the
control logic. The room air CO

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.
