COMMERCIAL ELECTRIC

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.

•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.
