control this temperature. The output hot water temperature can be adjusted either
manually using the main computer board's dipswitches or with the remote controller.
Using the dipswitches, 4 hot water output temperatures can be selected. Please
refer to the chart below.
� Once the remote control is connected to the water heater, it overrides the computer
board dipswitch settings. If the remote controller is disconnected from the unit, the
computer board will automatically revert to the temperature indicated by the
dipswitches. The computer does not store the remote controller's temperature in
memory. As such, the remote controller must remain connected to the water heater
at all times to maintain any temperature other than the 4 presets.
