APPENDIX
COMPONENT TERMINOLOGY
Heating Chamber: Made of heat insulator-coated copper tubes connected in series (serpentine), this chamber
is where the water ows through and is heated by over 20 feet (6 meters) of internal
heating elements.
Wiring Harness: is harness provides for the electrical connectivity between the heating elements,
mechanical relays, solid state relays, transformer and the supplementary load center with
quad circuit breakers.
Safety Relays: Eight relays completely cut power to the heating elements in case of a leak, temperature
cutout and rmware fault.
TRIACS: TRIACs regulate, via rmware control, the amount of power to the elements in order to
smoothly heat the water to the desired temperature. Residential units contain four (4)
TRIACs; commercial units contains eight (8).
Over-Temperature Switch: Monitors the internal temperature of the heating chamber.
If the temperature of residential water heater exceeds 158°F (70°C), the Over-Temperature
switch will shut down the heater as a safety precaution. e heater will automatically reset
this switch when the temperature drops back below 122°F (50°C).
If the temperature of commercial water heater exceeds 197.6°F (92°C), the Over-
Temperature switch will shut down the heater as a safety precaution. e heater will
automatically reset this switch when the temperature drops back below 161.6°F (72°C).
Hot Water Outlet: ¾˝ NPT and port for temperature sensing thermistor; heated water comes out at
this location.
Flow Sensor: is sensor determines the incoming water ow rate and communicates that to the
microprocessor controller board.
Incoming Water Inlet: ¾˝ NPT and port for temperature sensing thermistor; where cold water enters the heater.
Wiring Block Access: Electrical wire access to main terminating lugs (2 hot, 1 ground.) Electrical wire is top fed.
Quad Circuit Breakers: Simplifying installation, the circuit breakers provide an internal shut-o to the water
heater. e size of the circuit breakers is dependent on the amperage model of the unit.
Display: Backlit LCD with push-button control.
Controller Board: e brain of the heater. It controls the advanced features including temperature set point, time
of use, startup delay and gallon/time limits.
