Single Modulating Valve No Staging -
Stand-Alone Wiring
This confi guration operates as Stand-Alone (Figure 2, below) or
communicating with an AAON Unit Controller (Figure 3, page 6).
This confi guration can use either the MAXITROL ® 0-20 volt valve(s)
or the MAXITROL ® EXA STAR 0-10 volt stepper valve(s)—confi g-
ured at the factory. See Appendix C, page 26 for depiction.
If using a MHGRV-X Controller along with the MODGAS-X
Controller in Stand-Alone, the SAT Sensor always connects to the
MODGAS-X Controller.
WARNING: Do Not Connect Power To VOUT/Ground
Terminal Block!
