A. O. Smith’s new propriety advanced electronic water heater control, provides precise + or – 1ºF temperature control, which is ideal for industrial and food service applications where accurate hot water temperatures are needed.
Animated icons display detailed operational and diagnostic information.
Fault or alert messages appear if an operational issue occurs.
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.
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.
Modbus/BACnet compatible with optional Gateway interface.
Standard Permaglas glass lining. Exclusive process provides superior protection against corrosion in varying water conditions. Optional cement and epoxy linings.
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).

A. O. Smith’s new proprietary electronic water heater control provides precise + or – 1° temperature control that is ideal for industrial and food service applications where exact temperatures are needed.
The Operating Set Point is adjustable from 90°F/42°C to 190°F/88°C. The factory setting is 120°F/49°C.
Approved for 180°F/82°C sanitizing applications.
Animated icons display detailed operational and diagnostic information.
Fault or alert messages appear if an operational issue occurs.
Each element is constantly monitored and current on/off state is displayed, any element failure is reported and its exact location is shown, eliminates a need for field testing of elements.
Factory standard on board low water cutoff uses a remote electric immersion type probe to prevent energizing of the elements in the event of low water condition and eliminates accidental dry firing.
Units with multiple element contactors are sequenced on with one-second delay between stages. Prevents high amp electrical loads from hitting the electric system all at once and provides a smoother operating unit. Adjustable modulating mode is optional see options.
Control system automatically lowers the operating set point by a user defined value during setback periods. Seven-day clock may be programmed for night set back and or weekend shutdown to reduce operating cost and save energy.
