CONTROL PANEL INDICATIONS
LED display
1. Indicates the “Temperature Set Point” when blinking. Displays the “Actual
Temperature” when the display remains lit.
2. It displays both the “Preset Water Quantity” and the “Actual Water Quantity”.
“Combustion” - When lit indicates that the water heater is operating and burning
gas.
“Water valve” - Indicates one of the following three states:

flow is less than 0.66 gallons per minute (2.5 liters per minute)
3. When on and remaining lit, the firepower of the water heater is operating at either
the minimum or maximum operating point. The actual water temperature may not
reach the preset temperature. The water flow rate needs to be adjusted so the unit
is operating within its capacity range. This will allow the desired temperature to be
reached.
