Operation of the AQ250's Control Module is set by the

(beside the section labeled ZR). See Fig. 20 for location of
these DIP switches.

DIP Switch Configuration
AQ250 Control Module DIP Switch
Settings
AQ250 Control Panels come from the factory with pre-
defined settings for all DIP switches. These factory default
settings were chosen because they are commonly-used by
hydronics contractors across North America. That means
that most of the settings only need to be checked by the
installing contractor to make sure they're suitable for the
installation.
Although for many installations, these factory default
values for the Control Module and the Zoning Module(s)
are suitable, Resideo recommends that they be reviewed,
and changed as necessary, to get optimal performance of
the hydronic system controlled by the AQ2000 Series
products.
A chart of the setting options for each DIP switch is
attached to the inside of the DIP switch cover. More
detailed explanations for these settings, including the pre-
set factory defaults for each DIP switch, is shown in
Table 2.
When you finish setting the DIP switches for the Control
Panel, replace the front cover of the AQ250 Control Panel.
NOTE: The snap-on DIP switch cover is designed so it

cannot be removed (exposing the DIP switches)
when the front cover of the AQ250 Control Panel
is in place.
