Features and Controls
Setting water temperature:
Use Up or Down arrow key to regulate water temperature. The temperature setting will be displayed for 5
seconds to confirm your new selection.
The "Set Point" symbol indicates the desired temperature, NOT the current water temperature!
Water temperature can be adjusted by 1˚ increments from 59 to 104˚F (15 to 40˚C).
Automatic water heater start:
When water temperature is 1˚F (0.5˚C) lower than the Set Point, the heater will automatically turn on until water
temperature reaches Set Point plus 1˚F (0.5˚C).
The "Heater" icon lights up when the heater is on. It flashes when there is a request for more heat
but the heater has not yet started.
Inverted display:
Press and hold Blower for 5 seconds to invert the display. Note that the ˚F or ˚C icon is not displayed in reverse
mode. Follow the same procedure to return to default mode. If a power-up occurs, the display always returns to
default mode.
Temperature display unit:
Press and hold Light key for 5 seconds to display water temperature in either Fahrenheit (˚F) or Celsius (˚C).
Turning the fiber optic light on (option):
Pressing Light key turns fiber box (motor & light) on. Pressing again turns fiber box motor off but leaves light
on. A third time turns both motor and light off. A built-in timer turns fiber box off after 2 hours, unless it has
been manually deactivated.
The "Light" icon is displayed when fiber box light is on. It flashes when fiber box motor and light
are on at the same time.
Time & temperature display:
The display toggles every 5 seconds alternately showing the hourly time and the current water temperature.
