Aquatrol AQ2000 Series ® Electronic Controls for Residential Hydronic Heating Simple. Powerful. Affordable. Contractor Install Photos “Other products out there that I have dealt with are very difficult to set up, very frustrating by the time you are done and usually you have to go back a couple times and re adjust them. The Honeywell AQ panel is amazing, it’s very easy to install and to configure. You are going to get out of it what they say you are going to get out of it.” – Anonymous Johnstone Supply “The AQ2000 can do so much that homeowners are interested in today, including energy savings and prolonging the life of the equipment. It’s great for either new construction or retrofit applications. It is also very user-friendly. What we do, is we build the boiler board at the shop not out at the job site. We will build it and program it in the shop and then we send it out into the field to save time on the job. We spec it all the time. This is what we recommend, we don’t recommend anything else.” – Brian Streich Palo Heating, Cooling & Plumbing Ditter Heating and Cooling, Minnesota 2 Tri-State Mechanical, New York Downeast Energy, Maine AQ2000 Series Controls Fall Right Into Place Some hydronic system controls are basic and have limited features and functionality. Others are so complex that they’re difficult to install and use or service. Honeywell Aquatrol AQ2000 Series electronic controls combine functionality with ease-of-use, V8043E Zone Valves making them the perfect choice for nearly every HV190 Hygrovent application. For the AQ2000 Series, Honeywell worked directly with contractors to make sure the Baseboards new controls worked as simple as possible while V8043E Zone Valves meeting contractor needs. Honeywell also drew upon its control HV190 Hygrovent Hot technology knowledge Baseboards and experience gained Tempered AM-1 Mixing Valve through years as a leading hydronics V8043E5 Zone Valves HV190 Hygrovent Cold supplier in both Baseboards L6006 Aquastat Europe and North V8043E5 Zone Valves America. The result HV190 Hygrovent was the AQ2000 Series, with everything from a Baseboards V4043A Zone Valve 2-wire communications protocol that greatly simplifies Outdoor Sensor thermostat with easy expansion. We know most contractors don’t program a hydronic control everyday – with all the available Priority Domestic Hot Water AQ2 514B 4 AQ2 554P 2X D146 Differential Pressure Valve features and settings, it’s tough to remember what they all mean, especially if acronyms and icons are used. That’s why valuable HV190 Hygrovent and easily accessed diagnostics, set-up tools, troubleshooting, dot matrix LED, and menu items FC200 Gravity Check Valve with full English words make AQ controls more Baseboards accessible to those who only occasionally set up a hydronic system.

No need to use one of those zones to run your DHW. Control Panels – Single-Zone Systems For Retrofit Applications AQ2511BO Boiler Reset Control Panel Many of the great features of either the AQ251 or AQ252, but without multiple zone control: • Simple energy savings (from boiler reset) for homes with only one zone of heating Model Number Application AQ2511BO 1 Zone Reset The AQ2511B0 can be used with any non-communicating thermostat such as Honeywell’s VisionPRO IAQ, VisionPRO , FocusPRO , and PRO Series. ® ® ® How Does It Work? The AQ2511B0 Panel saves energy by automatically adjusting the boiler’s water temperature based on outdoor temperature. This allows the boiler to exactly match the heat it provides with the heat lost by the house. It’s like temperature cruise control for your customers house! The greatest energy savings is in the colder seasons where lower boiler temperature produces longer boiler run times, less cycling, more even heating of the house and less standby losses of heat going up the exhaust vent or into the boiler room where it’s not needed. 7 Expansion Zoning Panels Zone Valve s Addit Temp ional eratu re Pum ps Model Number Application AQ2541E0 Extends the capacity of an AQ2000 network by up to 16 additional zones AND one extra loop temperature AQ2554V2 4 zones of zone valves without end switches AQ2574V4 4 zones of zone valves with end switches AQ2554P2X 4 zones of pumps AQ2558P2X 8 zones of pumps AQ255 and AQ257 Expansion Panels Zoning Expansion Panel Features: • Controls up to either 4 or 8 zones depending on the model • Zone synchronization • Auto test function to check out zones at system start-up • R-C transformer and B-B data bus terminal connections and network communication for easy expansion • Status LEDs for easy diagnostics • Use with 2-wire “polarity insensitive” communicating thermostats • Expansion panels add-on simply and require only six field-installed wires to connect to the system • Integral low and line voltage wire conduit within panel enclosure allows you to connect multiple panels together without the need for running wire outside panels to connect them AQ254 Add-A-Temperature Injection/ Mixing Expansion Panels Even with 64 zones, all zones can still be diagnosed, checked out, and settings adjusted from the main panel without ever having to be in front of the thermostat itself! The convenient channel connectors allow you to easily add a zone without running wires outside of the panels. This eliminates the risk of having wires exposed to the homeowner outside of the panel, and makes for a clean and organized installation. To connect the panels, remove the wire channel plugs, reverse them and re-insert them. 8 Communicating Thermostats – Non-Programmable and Programmable AQ thermostats were designed exclusively for use with the AQ2000 Controls. They are the only thermostats you need for enhanced communication capabilities with multiple zones. Note: Non-communicating thermostats can be used for single-zone systems when using an AQ2511B0 Control Panel. Communicating AQ1000 thermostats are required for multi-zone systems.

In general, you should select an AQ2000 control panel to compliment your boiler’s capability. Use the Even the “smartest” boilers need zoning controls. For example, if your boiler already has outdoor resent on board, there’s no need for an AQ panel with reset capability. Instead, use an AQ250 control panel to provide smart zoning to the system, such as Zone synch, freeze protection, DHW priority, pump/valve exercise, etc... convenient selection chart below to select a panel that best suits your job! An AQ25A Panel has advanced set-up features that decrease installation time. Consider using an AQ25A panel with a programmable LCD screen to speed up your installation and provide your customer with the added value of having the outdoor temperature displayed on each AQ1000 thermostat!
