33 AquaSmart Boiler Control Manual
Troubleshooting
Lockout
The AquaSmart will lock out if any number of abnormal
conditions are detected.
HeatManager Technology
The Beckett AquaSmart comes equipped with the
Department of Energy (DOE) 2012 compliant Heat
Manager load-matching energy saving algorithm. The
Heat Manager saves fuel by dynamically changing the
temperature high operating limit to the minimum
temperature necessary to meet the heating demand.
The qualified service technician can adjust the
HeatManager algorithm to maximize comfort or energy
savings.
The HeatManager TM algorithm 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 sacrificing comfort.
The default HIGH efficiency 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
amount of connected radiation, boiler size, system
design temperatures, etc. The efficiency setting adjusts
how aggressively the HeatManager TM algorithm attempts
to reduce the boiler operating temperature. If a loss of
comfort is experienced, decreasing the efficiency setting
will help regain comfort at the expense of fuel savings
(see section A of “Programming Additional Options” for
instructions on changing the efficiency setting).
Display Boiler Status Mode
KEY:
D - Current operating temperature mode of boiler.
STANDBY will be displayed if neither the burner nor
circulator are energized.
CIRCULATING will be displayed if the circulator is
energized but the burner is not.
HEATING WTR will be displayed if a non-priority heat
call has caused the burner to be energized.
HEATING DHW will be displayed if a priority heat call
has caused the burner to be energized.
FREEZE RES will be displayed if the burner has
been running for 1 hour or the AquaSmart has been
locked out for 1 hour.
E - Current boiler water temperature measurement
F - Adjusted high limit when economizing
G - Lockout reason (see Lockout section under
“Troubleshooting”.)
STANDBY
WTR: 180F A D

LOCKOUT-
SENSOR ERROR C
G
1. SENSOR ERR - The sensor has either detected an
internal error or is not communicating properly with
the AquaSmart. The AquaSmart will not reset from
this condition until it can detect a properly working
sensor.
2. SELF-CHECK - An internal safety check, such as
the check on the B1 relay contacts, has failed. Hold
ENTER (RESET) key for 5 seconds to reset from
this condition. If the error occurs again, replace the
control.
3. CANCEL - The CANCEL (BACK) key was held for
5 seconds or longer, which temporarily suspends
the control’s operation. The control will resume
normal operation once the CANCEL (BACK) button
is released.
4. LOW WATER - A 2-in-1 sensor is installed and it
does not sense water. The control will resume
normal operation once water is detected and the
LWCO delay on time (if used) has expired.
ECONOMIZING-
HIGH LIMIT: 155F B
F
NOTE: When economizing, the display will toggle
between screens A and B every 5 seconds.
Frozen Plumbing and
Water Damage Hazard
If the residence is unattended in severely cold
weather, boiler control safety lockout, heating
system component failures, power outages or
other electrical system failures could result in
frozen plumbing and water damage in a matter
of hours.
For protection, take preventative actions such as
having a security system installed that operates
during power outages, senses low temperature and
initiates an effective action. Consult your qualified
service technician or a home security agency.
