Indoor air quality
Indoor Air quality (indoor sensor input): Terminal AQ accepts a
+2 to +10 Vdc signal with respect to the (AQ1) terminal. When
the signal is below it's setpoint, the actuator is allowed to
modulate normally in accordance with the enthalpy and mixed
air sensor inputs. When the AQ signal exceeds it's setpoint
setting and there is no call for free cooling, the actuator is
proportionately modulated from the 2 to 10 Vdc signal, with 2
Vdc corresponding to full closed and 10 Vdc corresponding to
full open. When there is no call for free cooling, the damper
position is limited by the IAQ Max damper position setting.
When the signal exceeds it's setpoint (Demand Control
Ventilation Setpoint) setting and there is a call for free cooling,
the actuator modulates from the minimum position to the full
open position based on the highest call from either the mixed
air sensor input or the AQ voltage input.

Function & Comments
Connects through circuit trace to 24V~ IN pin COM
Purge parameter reports input status (False with 0 VAC input-
True with 24 VAC input). When Purge status is True, heating and
cooling operation is prevented, the indoor blower and power
exhaust fan operate, the economizer actuator is positioned to
100%.
Connects through circuit trace to 24V~ IN pin HOT
ExFanVFDFlt parameter reports input status (Normal with 0 VAC
input-Alarm with 24 VAC input) when ExFType selection is
Variable Frequency Fan. When ExFanVFDFlt status is Alarm,
EX-FAN fan output is prevented.
