AQ250 SERIES HYDRONIC CONTROL PANELS
4 CONFIGURE THE CONTROL PANEL
Only two steps are required to set up the AQ250 Series Control
1. Check the DIP switch settings for the Control Module.
(see "AQ250 Control Module DIP Switch Settings" on
2. Check the DIP switch settings for each Zoning Module.
(see "Zoning Module DIP Switch Settings" on page 15)
AQ250 Control Module DIP Switch Location
Operation of the AQ250's Control Module is set by the
positions of its DIP switches, which are located behind the
blank cover in the left most section of the Control Module
(beside the section labeled ZR). See Fig. 20 for location of
these DIP switches.
Zoning Module DIP Switch Location
The AQ15540B (pump Zoning Module) and AQ15740B (valves
with end switches Zoning Module) both have DIP switches in
8-switch banks and are concealed behind snap-on covers, as
shown in Fig. 20.

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
