One Modulating Valve, One Ignitor,
One Stage (1V1IGN1S) -
Stand-Alone Wiring
This configuration operates as Stand-Alone ( Figure 2, below ) or
communicating with an AAON Unit Controller ( Figure 9, page 12 ).
This configuration 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 fixed heat stages can be used by using
Heat Relays 2, 3 & 4 below and up to 12 more additional
fixed 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.
