Setpoint determines where the economizer will
modulate the OA damper to maintain the mixed air
temperature.
Setpoint determines outdoor temperature when the
mechanical cooling cannot be turned on. Commonly
referred to as the Compressor lockout.

Displays only if CO2 sensor is connected. Setpoint for
Demand Control Ventilation of space. Above the
setpoint, the OA dampers will modulate open to bring
in additional OA to maintain a space ppm level below
the setpoint.
Displays ONLY if a CO2 sensor is NOT connected.
Displays only if a CO2 sensor is connected. Used for
Vbz (ventilation max cfm) setpoint. Displays 2 to 10 V
if <3 sensors (RA,OA, and MA). In AUTO mode
dampers controlled by CFM.
Displays only if a CO2 sensor is connected. Used for
Ba (ventilation min cfm) setpoint. Displays 2 to 10 V if
<3 sensors (RA, OA, and MA). Va is only set if DCV is
used. This is the ventilation for less than maximum
occupancy of the space. In AUTO mode dampers
controlled by CFM.
Only when AUX1 O = ERV
Setpoint for OA damper position when exhaust fan 1
is powered by the economizer.
Setpoint for OA damper position when exhaust fan 2
is powered by the economizer. Only used when AUX
is set to EHX2.
