2 Modulating Valves, 2 Ignitors,
1 Stage (2V2IGN1S) - Stand-Alone
Wiring
This configuration operates as Stand-Alone (
Figure 7, below
) or
communicating with an AAON Unit Controller (
Figure 10, page 13
).
This configuration is used to control two modulating gas valves (one on
each header), in which the first and second valves operate together for
one modulating stage. One valve is connected to Heat 1 Relay and the
second valve is connected to Heat 2 Relay.
NOTE:
Up to 2 additional fixed heat stages can be used by using
Heat Relays 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.
