1 When heating source is staged electric heat, the controller binary outputs BO6, BO5,
BO4, and BO3, are used to control discrete electric heat stages 1, 2, 3, or 4, respec-
tively.
2 When heating source is electric heat sequencer the heat analog output AO3 is used
to control a step controller/sequencer, up to six stages.

Draw-through
Blow-through
Note: Configure the supply fan to indicate the relationship of the supply fan to the heating
source. For example, if the heating source is located after the supply fan in the air stream,
blow-through should be selected. If the unit is heating and cooling (two-pipe changeover),
indicate the relationship of the supply fan to the secondary heat source, if installed.

1 When cooling source is hydronic, the cool analog output AO2 is used to control a
modulating valve.
2 When cooling source is DX cooling, controller binary outputs BO3, BO4, BO5, and
BO6 are used to control discrete compressor stages.
