In this conguration, the Two Modulating Valves wiring on the facing
page is the Primary portion and Figure 14, below is the Secondary por-

This conguration operates as Stand-Alone (Figure 6, page 9) or
communicating with an AAON Unit Controller.
NOTE: Up to 3 additional xed heat stages can be used by using
Heat Relays 3 & 4 below. If additional xed stages are
required, these should be congured and wired to the
AAON Unit Controller’s relays.
NOTE: The Four Modulating Valves Primary/Secondary
configuration is not supported when using I
