When you finish setting the DIP switches for all the Zoning
Modules, replace the front cover of the AQ25A Control Panel
and the cover of each Expansion Zoning Panel.
NOTE: The snap-on DIP switch covers are designed so they
cannot be removed (exposing the DIP switches)
when the front cover of the AQ25A Control Panel is in
place.

Zone Address: The positions of these 4 DIP switches define the unique address for
each zone on the AQUATROL network. For each group of 4 zones, there can be only
one DIP switch in the right hand (ON) position.
The correct DIP switch settings for each zone module are:
• First Zone (1-4) Module: 1 = ON position; 2, 3, and 4 = OFF position
• Second Zone (5-8) Module: 2 = ON position; 1, 3, and 4 = OFF position
• Third Zone (9-12) Module: 3 = ON position; 1, 2, and 4 = OFF position
• Fourth Zone (13-16) Module: 4 = ON position; 1, 2, and 3 = OFF position

• If set to SYNC, zone synchronization is enabled.
• If set to NOT, zone synchronization is disabled.

• If zone valves are normally closed (N.C.), set the NC/NO DIP switch to the OFF
position.
• If zone valves are normally open (N.O.), set the NC/NO DIP switch to the ON
position.
7
• If set to Group (ON position), the AUX Pump contacts on the Control Module are
switched when any of the zones on this Zoning Module are active.
• If set to - (OFF position), the AUX Pump contacts are not affected by activity on
these zones.
8
• If set to 2-stage (ON position), then 2-stage operation is activated on thermostat
inputs. The zoning module operates as two 2-stage zones.
• If set to 1-stage (OFF position), then operates as four 1-stage zones.
