Secondary Board 2V1IGN1S - Stand-Alone Wiring
Figure 6: Secondary Board 2V1IGN1S Stand-Alone Wiring Diagram
Secondary Board (2V1IGN1S) -
Stand-Alone Wiring
In this configuration, the Two Modulating Valves wiring on the facing
page is the Primary portion and
Figure 6, below
is the Secondary por-
tion, thus creating four modulating valves as one stage.
This configuration operates as Stand-Alone (
Figure 6, below
) or
communicating with an AAON Unit Controller (
Figure 14, page 17
).
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 a MHGRV-X Controller along with the secondary MODGAS-
XWR2 Controller in Stand-Alone, the SAT Sensor always attaches to
the Primary MODGAS-XWR2 Controller.
