ELECTRIC WATER HEATERS
ADVANCED ELECTRONIC CONTROL
A. O. Smith’s new propriety electronic water
heater control, provides precise + or - 1ºF
temperature control, that is ideal for industrial
and food service applications where accurate
hot water temperatures are needed.
EASY-TO-READ TEXT
• Animated icons display detailed operational
and diagnostic information. Fault or alert
messages appear if an operational issue
occurs.
LOW WATER CUT OFF
• Factory standard on board low water cut-off
uses a remote electronic immersion type
probe to prevent energizing of the elements
in the event of low water condition and
eliminates accidental dry firing.
PROGRESSIVE MODULATING
• Matches number of elements to current
load conditions. Rotates and lead lags
element loads to provide long life and equal
wear.
ECONOMY MODE OPERATION
• Control system automatically lowers the
operating set point by a programmed value
during user defined time periods. Seven-day
clock may be programmed for night set
back and or weekend shutdown to reduce
operating cost and save money.
BMS COMPATIBLE
• Modbus/BACnet compatible with optional
Gateway interface. Call 888 WATER02 for
more information.
PERMAGLAS® GLASS LINING IS
STANDARD
• Exclusive process provides superior
protection against corrosion in varying
water conditions. Cement and Epoxy linings
are optional.
ASME CODE CONSTRUCTION
• All models are constructed to the
requirements of ASME and are available in
125, 150 and 160 psi working pressures
(125 psi working pressure - standard).
Consult factory for ASME code tanks with
greater or lesser working pressures and
special configurations or materials.
INCOLOY IMMERSION HEATERS
• Heavy-duty elements have incoloy
sheathing: provide excellent protection
against oxidation and scaling. The input
ranges from 15kW to 900kW (see
accompanying chart).
FUSING
• Control and power circuit fusing to meet
N.E.C.
COMPLIANCE
• Meets the standby loss requirements of
the U.S. Department of Energy, NRCan and
current edition of ASHRAE/IES 90.1.
MAGNETIC CONTACTOR(S)
• Heavy duty UL rated for 100,000 cycles.
OTHER STANDARD FEATURES
• Color-coded circuitry for easier servicing
• Anode rods for maximum corrosion
protection
• Standard voltages include 208, 240, 380,
400, 415, 480, 600 volt single or threephase
• International voltages available (consult
factory)
• Factory-installed terminal block(s)
• Temperature and pressure relief valve,
supplied but not installed
OPTIONAL DUAL-ENERGY SOURCE
CAPABILITY
• Provides emergency back up energy source
or winter/summer boiler operation. Can
be specified with optional water to water
or steam to water heat exchangers. Both
single and double-wall heat exchangers are
available. Complete control packages can
be factory-installed for hook-up and run
capability.
THREE YEAR LIMITED WARRANTY
