7 Configure The Control Panel's DIP
Switches
Setting up an AQ250 Control Panel is quick, simple and
straightforward. Only two steps are required – checking the
DIP switch settings for the Control Module and checking the
DIP switch settings for the Zoning Module(s).
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 Figure 15 for location
of these DIP switches.
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) will be
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.
DIP Switch Configuration
Control Module
1. 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.
Zoning Modules
2. The AQ1554P2 (pump Zoning Module) and AQ1574V4
(valves with end switches Zoning Module) both have
DIP switches in 8-switch "banks" and are concealed
behind snap-on covers as shown in Figure 15. A chart
of the different settings for each DIP switch is attached
to the inside of the DIP switch covers. More detailed
explanations for these DIP switch settings, including the
pre-set factory defaults for each, is shown in Table 3.

3. The only difference in setting up the AQ1554P2 and
AQ1574V4 Zoning Modules is that DIP switch #5 for the
AQ1554P2 needs to be set to "PUMP" or "VALVE",
according to whether this Zoning Module will be used
for zoning with either pumps or zone valves without end
switches. DIP Switch #5 is not functional on the
AQ1574V4 Zoning Module, as this Zoning Module can
only be used for valve zoning.

Check the DIP switch settings and, if necessary, change the
position of the DIP switches to suit the desired operation of
the hydronic installation.
4. DIP switches #1-4 define the "identity", or "address", of
each zone on the AQUATROL network. This is how the
Control Module knows that – for example – the zone
labeled "Zone 1" on the first Zoning Module is different
than the zone labeled "Zone 1" on a second Zoning
Module.
5. If there is more than one Zoning Module connected to
the AQ1500 Control Module, DIP switches #1-4 MUST
be set to uniquely identify each zone in the installation.
