Stand-Alone Wiring
This configuration operates as Stand-Alone (Figure 2, below) or
communicating with an AAON Unit Controller (Figure 9, page 12).
This conguration is used to control one modulating valve, which must
be placed on the gas valve 1 header (attached to Heat 1 Relay).
NOTE: Up to 3 additional xed heat stages can be used by using
Heat Relays 2, 3 & 4 below and up to 12 more additional
xed stages can be added by using the 12-Relay E-BUS
Expansion Module. (Figure 8, page 11).
If using an MHGRV-X Controller along with the MODGAS-XWR2
Controller in Stand-Alone, the SAT Sensor always attaches to the
MODGAS-XWR2 Controller.
