Quick RefeRence Guide

The Beckett AquaSmart is an advanced boiler control designed for use on residential and light commercial

boiler systems. All models include the option of enabling Beckett HeatManager™ dynamic temperature reset

that, when selected, provides up to 20% fuel consumption savings. The control includes a backlit LCD digital

display with touch pad to easily program temperature limits, differentials, and other advanced options. The

AquaSmart also has memory storage of system history for help with diagnostics and troubleshooting.

Do Not Use This Control in an Application that is Not Within the Ratings

Listed in This Section. Improper Control Operation May Result.

Electrical Shock, Fire, Explosion and Burn Hazards

This control must be installed, adjusted and put into operation only by a trained, licensed, qualied

professional or service agency in accordance with the National Electric Code ANSI/NFPA 70 (Canada CSA

C22.1) state, local codes and authorities having jurisdiction.

The installer must carefully read and follow the installation and service instructions contained in this pamphlet and in

the owner’s manual. Make them available to the equipment owner, so they can be kept for future reference.

Please refer to the AquaSmart Owner’s Manual for more detailed instructions and advanced

programming options.

Figure 1 - Getting to know the AquaSmart 7600 Series Control

OEM Installation: When replacing an OEM-installed

AquaSmart, consult the appliance manufacturer’s wiring

diagrams and instructions for additional information.

Retrot Installation: The AquaSmart can be used to

replace most standard boiler temperature controls. For a

cross-reference of compatible replacements, refer to

Owner’s Manual.

There are two basic methods for mounting the AquaSmart

to the boiler.

Sensor/Immersion Well Mounting – This is the

most common method. If the existing well is not

suitable for any reason, a standard design aftermarket

immersion well with the proper dimensions can be

purchased from a HVAC distributor. The AquaSmart

can then be mounted in the typical way.

Surface Mounting – This is sometimes required

and is part of the AquaSmart base design. The base

has adequate clearance built-in to accommodate the

temperature sensor lead exiting the back of the

control. A 48” extension cable (Pt. No. 52120) can

be purchased separately for applications where

needed.

Installation

B. Temperature Low Limit

In any mode or screen other than an OPTION sub-

menu, press the “LOW LIMIT” key.

The temperature displayed is the current setting.

Use the “▲” and “▼” keys to select the desired

setting. Tap the button to increase or decrease the

temperature by 1°, or hold it to increase or decrease

the temperature by 5° at a time. For cold-start

operation, turn the low limit off by pressing the down

arrow key repeatedly until OFF is displayed.

IMPORTANT: To prevent ue gas condensation and

reduce fatigue caused by thermal cycling on

conventional (non-condensing) boilers, the LOW

LIMIT set point should be 150° F or above.

NOTE: Boiler manufacturer’s temperature

requirements supersede this recommendation.

Press the “ENTER (RESET)” key. Conrm the

setting by pressing “ENTER (RESET)” again if the

value is correct, or “CANCEL (BACK)” if it is not.

C. Temperature High Limit Differential

In any mode or screen other than an OPTION sub-

menu, press the “HIGH DIFF” key.

The temperature displayed is the current setting.

Use the “▲” and “▼” keys to select the desired

setting. Tap the button to increase or decrease the

temperature by 1°, or hold it to increase or decrease

the temperature by 5° at a time.

Press the “ENTER (RESET)” key. Conrm the

setting by pressing “ENTER (RESET)” again if the

value is correct, or “CANCEL (BACK)” if it is not.

D. Temperature Low Limit Differential

In any mode or screen other than an OPTION sub-

menu, press the “LOW DIFF” key.

The temperature displayed is the current setting.

Use the “▲” and “▼” keys to select the desired

setting. Tap the button to increase or decrease the

temperature by 1°, or hold it to increase or decrease

the temperature by 5° at a time.

Press the “ENTER (RESET)” key. Conrm the

setting by pressing “ENTER (RESET)” again if the

value is correct, or “CANCEL (BACK)” if it is not.

To ensure smooth appliance operation, the AquaSmart

requires a separation between the High and Low limits no

less than the greater differential plus 5°F.

For example: If the High Limit is set to 180°F, the High Diff

to 20°F, and the Low Diff to 10°F, the control will not allow

a Low Limit above 155°F (180°F - 20°F [the greater of the

two differentials] - 5°F = 155°F).

A. Temperature High Limit

In any mode or screen other than an OPTION sub-

menu, press the “HIGH LIMIT” key.

The temperature displayed is the current setting.

Use the ▲ and ▼ keys to select the desired setting.

Tap the button to increase or decrease the

temperature by 1°, or hold it to increase or decrease

the temperature by 5° at a time.

Press the “ENTER (RESET)” key. Conrm the

setting by pressing “ENTER (RESET)” again if the

value is correct, or “CANCEL (BACK)” if it is not.
