AQ255 and AQ257 Series

Expansion Zoning Panels

PRODUCT DESCRIPTION

The AQ255/AQ257 Series Expansion Zoning Panels provide

additional zoning capacity for an existing hydronic installation

controlled by an AQ2000 Series Boiler Control Panel such as

an AQ250 Relay Boiler Control, an AQ251 Reset Boiler

Control, or an AQ252 Universal Injection/Mixing Boiler Reset

Control.

FEATURES

The AQ255/AQ257 Series Expansion Zoning Panels have the

following features:

• Availability of 4 Expansion Zoning Panels.
• Zone control of either pumps or zone valves, in

multiples of 4 zones

• 4-zone or 8-zone models for pump zoning; 4-zone

models for zone valves

• Ability to use both zone valve models and zone pump

models in the same installation

• Zone valve panels contain an AQ10X38 transformer

(power supply module), which connects to 120 Vac

power and supplies 24 Vac power to the Zoning

Module.

• Communications between components via the

AQUATROL® network, using communication bus

wiring.

• Any panel can be configured to activate a group pump

when zones are active

• Zone valve models can be used with Normally Open or

Normally closed valves

• Can be installed up to 500 ft. away from main AQ2000

Control Panel, for convenient operation of remote

zoning equipment
