Two Modulating Valves Staged - Stand-Alone Wiring
Figure 4: Two Modulating Valves Staged Stand-Alone Wiring Diagram
Two Modulating Valves Staged -
Stand-Alone Wiring
This configuration operates as Stand-Alone (Figure 4, below) or
communicating with an AAON Unit Controller (Figure 8, page 11).
If using an MHGRV-X Controller along with the MODGAS-XWR
Controller in Stand-Alone, the SAT Sensor always attaches to the
MODGAS-XWR Controller.
NOTE: Up to 12 fi xed stages can be added by using the 12-Relay
E-BUS Expansion Module. (Figure 5, page 8).
WARNING: Do Not Connect Power To VOUT/Ground
Terminal Block!
