Features of ICON System Module
Water heater digital display on control board for setting and displaying the temperature setpoint. Pressing
temperature UP and DOWN buttons changes the temperature setpoint. Temperature format may be
displayed in °F or °C.
Single control board with plug in wiring controls temperature, ignition, and blower operation.
Plug in wiring reduces chance of miswiring.
Burner ignition with direct spark ignition – A high voltage spark jumps from the spark rod to the burner
surface to ignite the gas.
Water heater digital display will show diagnostic codes in the event the water heater needs servicing. Aids
in diagnosing and servicing the water heater.
