3. How does this new HeatManager logic compare to the HeatManager Classic we are familiar with?
As opposed to the new HeatManager calculation the Beckett HeatManager Classic works to hold off the burner from fi ring if
the outlet water temperature from the boiler is warm enough to still heat the home. This causes the burner to cycle less and
indirectly lowers the average boiler water temperature, which generates fuel savings.
The Beckett AquaSmart HeatManager calculation adjusts the high limit of the boiler based how long the system is on or off. If
the system is calling for heat, the adjusted high limit will increase over time but never above the high limit set point. If the sys-
tem is not calling for heat, the adjusted high limit will decrease over time. The minimum temperature the AquaSmart will allow
the adjusted high limit to drop is based on a number of factors including the high limit, low limit, differentials, and HeatManager
effi ciency settings.
The AquaSmart HeatManager never overrides the low limit, which can be benefi cial in keeping hot water available in tankless
coil systems. If Domestic Hot Water Priority (DHWP) is set on one of the AquaSmart's inputs, a priority heat call will temporarily
override the operation of the HeatManager.
4. How do you know how to set the HeatManager function for different applications?
The default HIGH effi ciency setting should work best for most systems. However, there are many system factors that may have
an effect on its ability to react to changes quickly enough and supply adequate heat, such as the amount of connected radiation,
boiler size, system design temperatures, etc. The effi ciency setting adjusts how aggressively the HeatManager calculation at-
tempts to reduce the boiler operating temperature. If a loss of comfort is experienced, decreasing the effi ciency setting will help
regain comfort at the expense of fuel savings.
5. How will the new HeatManager calculation interact with a system utilizing a tankless coil?
The HeatManager calculation will positively affect the hot water available in a system utilizing a tankless coil.
Because the HeatManager does not change the low limit setting to accommodate the tankless coil or "hold off"
the burner when it needs to fi re, you can expect more consistency in your hot water supply.
6. Does the AquaSmart have any other fuel effi ciency features?
Yes, one of the AquaSmart's advanced features is the Circulator-off delay. Once the call for heat is satisfi ed
the circulator-off delay holds the circulator pump on for the delay period. The Circulator-off Delay increases the effi ciency of the
system by delivering more heat to the Zones instead of keeping it in the boiler or losing it up the chimney.
7. What other advanced features does the AquaSmart have?
There are several. They are as follows:
Circulator-On Delay: Once a call for heat is received the Circulator-On Delay holds the circulator pump off for the delay period.
This allows the boiler to heat up faster and spend less time in the condensing range. Consequently this reduces the amount of
condensation produced, which enhances the life of the boiler.
Domestic Hot Water Priority: The Domestic Hot Water Priority (DHWP) setting ensures that hot water will be produced when
needed by temporarily overriding the HeatManager Dynamic Temperature Reset functionality when there is a call for domestic
hot water. The Domestic Hot Water Priority has a maximum duration of twenty minutes. Circulator Seize-up Protection: There
are times when the circulator may be inactive for an extended period of time, especially during the summer months. This
feature will briefl y energize the circulator periodically exercising the circulator pump, which helps to prevent seize-up during the
summer months. Automatic Freeze-up Resistance: Automatic Freeze-up Resistance is when the circulator circulates water
to all zones calling for heat during most control or system failure modes which delays or prevents pipes from freezing. This
normally happens when the burner has been in failure for one hour or the AquaSmart has been in lockout for one hour (Except
in low voltage situations).
