Installing And Connecting Components Is
Easy With honeywell's AQ2000 Controls
Simplified Wiring
• Logical interface — The modules in all AQ2000 control panels are laid
out in the same way, so there is no big learning curve
• Six pairs of 24 Vac terminals on the secondary of the AQ10X38
transformer for neat, organized wiring
• Connecting panels for multi-zone systems is easy thanks to integral
wiring channels that serve as snap fit connectors between components
for easy installation and alignment of panels
• Multiple ground screw connections and conduit knockouts for neat,
organized wiring
• Straightforward terminal strip design offers plenty of room for wiring;
plus, terminals are located in the front
• All relay and reset control panels* are factory pre-wired and come
complete with transformer, controller and zoning modules for up to 4
zones, minimizing installation time; All control panels are expandable up

to 16 zones, (and up to 64 zones, using AQ254 "Add-A-Temperature"
Expansion Control Panels) communicating on the same network
• The AQ2511B0 and AQ2521M0 reset control panels can provide
outdoor temperature compensation for systems that are configured as
one large zone; Ideal for retrofitting outdoor temperature compensation
to an existing installation without zoning changes
Additional Easy Connections
• Switching from pumps to valves is easier than ever because the
AQ2504B2, AQ25A4B2, AQ2514B2 and AQ2524M2 control
panels have built-in zoning modules that can be used by either
pumps or 2-wire zone valves (without end switches)
• Only two wires are required to connect thermostats, plus
polarity doesn't matter; that's especially valuable for retrofit jobs
where the thermostat wires are already in the wall
*AQ25511B0 reset panel does not include a zoning module
