When the water heater in working condition, the display will take turns showing the current real‐
time hot water production and real‐time gas consumption, the figures will be changed accord the
actual working conditions, so that users can understand the water heater current working
conditions.
For example: When the real‐time information display "12.0 L / min", indicates that current real‐
time hot water production by water heater per minute 12 L. When the real‐time information
display "2.0m³/h", indicates that current real‐time gas consumption by water heater per hour
2.0m³
