Surface mounted thermostats respond to tank surface temperatures to sense a call for heat, set point temperature settings and high limit (ECO) activation.

  • Page 6: Sequence Of Operation

    SEQUENCE OF OPERATION Residential and light duty commercial electric water heaters are designed to operate using several different operating modes. The common modes and sequence of operation are as follows: 1. Single Element Operation. 2. Double Element Non-Simultaneous Operation (single phase). 3.
  • Page 7 SEQUENCE OF OPERATION Non-Simultaneous and Simultaneous Operation Double element electric water heaters are designed to operate in either Non-Simultaneous or Simultaneous mode. Non-Simultaneous Mode: Allows only one heating element to operate at a time. For example, when the tank is cold, the upper element is energized first, heating the top of the tank.
  • Page 8 SEQUENCE OF OPERATION A 4 wire, double element heater wired for simultaneous operation is essentially two single element systems operating independently. The heaters are wired internally with two independent circuits, one circuit for each thermostat/element combination. When installed using a two wire service, the blue and red (or white) wires will be connected together, likewise black and yellow wires will be connected together.
  • Page 9 SEQUENCE OF OPERATION Sequence of Operation- Double Element, Non-Simultaneous Operation, 3 Phase. Line voltage is applied across terminals L1 & L3 of upper thermostat. Likewise, Line Thermostat closed Closed at terminal T2 voltage is applied to terminal L3 of lower thermostat.
  • Page 10 SEQUENCE OF OPERATION Sequence of Operation- Double Element, Simultaneous Operation, 3 Phase. Line voltage is applied across terminals L1 & L3 of upper thermostat. Line voltage also extends to terminal L1 of lower thermostat. Also, line voltage is applied to terminal L3 Closed Thermostat closed of lower thermostat.
  • Page 11 SEQUENCE OF OPERATION Some electric utility companies will offer discounts for using electricity during “Off Peak” Times of the day. The system allows the use of an “Off Peak” meter, which interrupts power to the lower element during high power demand periods. Sequence of Operation- Double Element, Non-Simultaneous Operation, Single Phase, Off Peak.

  • Page 12: Troubleshooting

    TROUBLESHOOTING Most common cause for improper electric water heater operation can be linked to heating element failure. When troubleshooting an electric water heater with the incidence of “No Hot Water” or “Insufficient Amount of Hot Water,” It’s always a good idea to check the heating elements first by following the procedure on page 15. Common Heating Element Failures: 1.
