Function & Comments
24 VAC common connection to power the economizer board.
Connects through circuit traces to C/COM terminals and pins
distributed on the economizer board.
24 VAC hot connection to power the economizer board.
Connects through circuit traces to R/24V~ terminals and pins
distributed on the economizer board.
Connects through circuit trace to 24V~ IN pin HOT
OAH parameter reports input status (0-100%H). Used in outdoor
air enthalpy
calculation for dual enthalpy economizer free cooling
changeover.
Connects through circuit trace to 24V~ IN pin COM
Connects through circuit trace to 24V~ IN pin HOT
SAH parameter reports input status (0-100%H). Unused in
current control revision.
Connects through circuit trace to 24V~ IN pin COM
Connects through circuit trace to 24V~ IN pin HOT
IAQRange parameter sets the CO2 parts per million measured
by the indoor air quality sensor when it outputs 10 VDC; IAQ
parameter reports input status (0-5000ppm). Used for demand
ventilation functions if the NetIAQ parameter indicates ?Unrel.
Connects through circuit trace to 24V~ IN pin COM
Connects through circuit trace to 24V~ IN pin HOT
OAQRange parameter sets the CO2 parts per million measured
by the outdoor air quality sensor when it outputs 10 VDC; OAQ
parameter reports input status (0-5000ppm). Used for demand
ventilation function when DVent-Mode selection is Diff between
IAQ and OAQ and the NetOAQ parameter indicates ?Unrel.
Connects through circuit trace to 24V~ IN pin COM
Connects through circuit trace to 24V~ IN pin HOT
MOA-Range parameter sets the cubic feet per minute/liters per
second measured by the air monitoring station sensor when it
outputs 10 VDC; Fr Air parameter reports input status (0-
50000CFM/23595lps). Used for economizer minimum position
reset in speed-controlled indoor blower applications.
