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,
Honeywell 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.
