1. What is the AquaSmart?  
The Beckett AquaSmart is an advanced triple acting boiler temperature control (BTC) designed for use on residential and light com-  
mercial boiler systems. A triple acting BTC incorporates a High and Low limit with differential functions. The triple acting BTC also  
controls circulator functions. This employs a BTC that acts in reverse. The reverse BTC opens to turn the circulator off if boiler water  
temperature drops below a set temperature, typically to maintain a minimum boiler temperature in both the High and Low limit func-  
tions. The circulator circulates the heat transfer uid to the heated zone. The Beckett AquaSmart comes equipped with the Depart-  
ment of Energy (DOE) 2012 compliant HeatManager. All models include the option of enabling the Beckett HeatManager load-match-  
ing energy saving calculation. When selected it provides up to 20% fuel consumption savings.  
2. What is the Beckett HeatManager Calculation?  
The HeatManager saves fuel by dynamically changing the temperature high operating limit to the minimum temperature necessary  
to meet the heating demand. The contractor can adjust the HeatManager calculation to maximize comfort or energy savings. The  
HeatManager calculation is designed to operate the boiler at its lowest possible temperature while still meeting the heating demand.  
By dynamically changing the boiler temperature, it is designed to reduce the energy used by the system without sacricing comfort.

Advanced 2N1 Self-checking Sensor: The 2N1 AquaSmart sensor measures both “boiler water temperature” and “presence of wa-  
ter” (low water cut-off) functions. The AquaSmart’s 2N1 sensor continually performs internal self-checks to determine if the sensor is  
operating properly. With the AquaSmart you can also view Boiler Cycle History  
8. Is the AquaSmart available for Gas applications?  
Yes, both Oil and Gas offerings are available.  
2N1 Sensor with Low  
Water Cut-off  
9. What can cause the AquaSmart to lockout?  
There are four reasons for the AquaSmart to lockout.  
The AquaSmart will lockout when the 2N1 Self-checking Sensor either detects an internal error or is not communicating prop-  
erly with the control. The AquaSmart will not reset from this condition until it can detect a properly working sensor.  
When an internal safety check, such as the check on the B1 relay contacts has failed, the control will lockout. To reset from this  
condition hold the “ENTER (RESET)” key for 5 seconds. If the error occurs again, replace the control.  
The AquaSmart will lockout when the “ENTER (RESET)” key is held for 5 seconds or longer. (Manual Shutdown) The control’s  
operation will be temporarily suspended and will resume normal operation once the “ENTER (RESET)” button is released.  
The AquaSmart will lockout when a low water condition is detected. If the control is set to “MAN” you will need hold down the  
“ENTER (RESET)” key for 5 seconds. If the control is set on “Auto” it will reset automatically.  
10. What options do I have when mounting the AquaSmart?  
There are two basic mounting options for the AquaSmart™ control, the immersion well method and the surface method. The surface  
method is also referred to as a wall mount. Mounting the AquaSmart directly to the immersion well is the most common method. The  
AquaSmart temperature sensor mounts in standard immersion wells. Surface mounting is sometimes required and is part of the  
AquaSmart™ base design. It is also retrot compatible with most standard boiler temperature controls.  
11. When wiring the AquaSmart does the color of the wires have any signicance?  
Besides for using the white wire for neutral, black for hot and green for the ground there is no signicance to the colors of the wires.  
On the other hand the terminals on the AquaSmart are approved for copper wire only.  
12. What are the electrical ratings for the AquaSmart?  
The Burner Circuit is 120Vac for the oil control and 24Vac for gas while the Circulator Control is 120Vac. The AquaSmart has a  
120Vac Zone Control and is 24 Vac thermostats compatible.  
13. Since the AquaSmart is made of plastic will the wiring knockouts hold up?  
Yes, the AquaSmart control has ve different knockouts. There is one on both the right and left side and three more on the bottom of  
the unit. The knockouts are reinforced with a steel plate to secure conduit connectors and provide grounding.  
14. How difcult is the AquaSmart to program?  
The AquaSmart control is equipped with an installer easy-to-use keypad along with a prominent  
backlit LCD digital display. All of the basic functions, including High and Low Limit and High and  
Low Differential are easily accessible on the face of the programming panel.  
15. What happens if I inadvertently select temperature settings that overlap each other?  
The AquaSmart will not allow overlapping temperature settings to be selected. For example: If the HIGH LIMIT is set to 180°F and  
both the HIGH DIFF and LOW DIFF are set to 10° F, the control will not allow a LOW LIMIT above 165° F to be entered.

16. Generally, what is the typical operation of the AquaSmart?  
Following are typical responses to a variety of system actions.  
System Action  
AquaSmart Response  
Burner is turned on until the water temperature reaches the low limit plus the low differential.  
ZC is turned off until the water temperature reaches the low limit plus the low differential  
Maintaining the Low Limit  
Burner is turned on as long as the water temperature is below the high limit. Circulator is  
turned on after circulator-on delay if the low limit is satised.  
Thermostat Call for Heat  
Burner is turned off  
Circulator is turned off after circulator-off delay  
Thermostat is Satised  
ZR Call for Heat  
Burner is turned on as long as the water temperature is below the high limit.  
Burner is turned off.  
ZR is Satised  
Burner is turned off until the water temperature falls below the high limit minus the high  
differential.  
Maintaining the High Limit  
17. How can I be sure that I have installed the AquaSmart correctly?  
When you have completed the installation of the unit you will go through the Control Checkout Procedure.  
These procedures are typical for the default conguration of the control. Before beginning the AquaSmart checkout procedure,  
make sure the control is wired and congured as is required by the application. You will nd the steps for the check out procedure  
in the AquaSmart Information and Operation Manual.  
CAUTION! Do not leave the installation site if the AquaSmart operation did not match the descriptions in any of the steps in the  
checkout procedure. Make all necessary adjustments until the correct operation is veried. The checkout procedure helps to verify  
that the high and low limits are working properly and that the thermostat is wired correctly to the control.  
18. Does the AquaSmart provide any other Benets?  
Yes, there are benets provided in several different areas.  
The homeowner should know that in a short period of time the AquaSmart will pay for itself when the HeatManager is enabled.  
That’s right. Due to the up to 20% energy savings from our energy efcient features the homeowner will realize up to $300 sav-  
ings per year in a typical home. With conserving energy and saving money the AquaSmart is precisely what consumer is looking  
for.  
Additionally, the homeowner benets from increased comfort and peace of mind. The AquaSmart will give priority to  
a call for Domestic Hot Water. This helps to ensure a steady supply of hot water to the home. The AquaSmart will also  
give the homeowner added peace of mind due to its automatic freeze-up resistance feature.  
Our Environment denitely Benets with the AquaSmart. Did you know that if every Boiler in the United States used the  
AquaSmart control it would reduce our nation’s fuel consumption by the equivalent of 24.6 million barrels of fuel/year?  
We all can be a part of this solution.
