These factory default settingswere chosen because they are commonly-used by hydronicscontractors across North America. That means that most of thesettings only need to be checked by the installing contractor tomake sure they’re suitable for the installation.Although for many installations, these factory default values forthe Control Module and the Zoning Module(s) are suitable,Honeywell recommends that they be reviewed, and changedas necessary, to get optimal performance of the hydronicsystem controlled by the AQ2000 Series products.A chart of the setting options for each DIP switch is attached tothe inside of the DIP switch cover. More detailed explanationsfor these settings, including the pre-set factory defaults foreach 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 itcannot be removed (exposing the DIP switches)when the front cover of the AQ250 Control Panel is inplace.M23731AAQ15540B
