Menu Structure
IMPORTANT: Table 6 illustrates the complete hierarchy.
Your menu parameters may be different depending on your
configuration. For example if you do not have a DCV (CO
2
)
sensor, then none of the DCV parameters appear.
The menu hierarchy has been modified to reflect controller
configuration for 2--speed indoor fan application in the
Staged Air Volume option.
NOTE: Some parameters in the menus use the letters MA
or MAT, indicating a mixed air temperature sensor
location before the cooling coil. This unit application has
the control sensor located after the cooling coil, in the fan
section, where it is designated as (Cooling) Supply Air
Temperature or SAT sensor.
