FUNCTION
Defines what kind of OAU is
installed
Determine what outside air fan
curve to use
Determine what exhaust air fan
curve to use
Tells OAU to run in unoccupied
mode
Tells OAU to shut off if one of its
fans fail
Determine if the OAU's wheel is a
modulating one
Sets Design OA CFM for ventilation
Sets absolute minimum OA CFM for
ventilation
Determine how to control the
exhaust fans
Sets offset CFM setpoint of exhaust
based on intake
Sets required building pressure
Determine if there is tempering
heater installed
Sets the outside temp and below to
allow tempering
Sets target supply air temperature
during tempering
Sets outside air curve correction
factor
Sets exhaust air curve correction
factor
Tells RTU to adjust fan speed for
low outside air CFM
