3.5 Use function mode
In standby mode (ie, no water status), press the
function (
@
) key, you can select "
Auto
", "
Eco
",
"
normal
” in turn. The system default mode is
set to
normal
.
Three types of function mode instruction
• Normal
mode (default): This mode allows
the user to set the temperature. The "Auto"
and "Eco" display lights are not lit.
• Auto
mode: ("Auto" display light is bright.)
This mode will adapt the output tempera-
ture based on the water inlet temperature.
This automatically adjusts the set tempera-
ture (as shown in Figure 3.3) allowing users
to get the most comfortable hot water sup-
ply.

Note:
Under the Auto mode, after the water
heater is switched on, the temperature dis-
played is the one set before the heater starts
to work. The temperature will not change ac-
cording to the local water temperature change
after the heater starts to work.
• Eco
mode: ("Eco" display light is bright.) In
Eco mode, after calculation by the microcom-
puter the water heater automatically adjusts
the amount of gas supply. This not only saves
gas, but can also guarantee a constant water
temperature to meet the requirements of us-
ers. In Eco mode, the user can freely select
the desired water temperature by pressing
the up/down keys to adjust the temperature.
This does not exit the Eco mode. To exit the
Eco mode the user needs to enter the stand-
by mode and press the function key again to
change modes.
3.6 Instant hot water production
and real time gas consumption
display
When the water heater is working, the display
will take turns showing the current real time
hot water production and real time gas con-
sumption, the figures will be changed accord-
ing to 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", this indicates that the real
time hot water production is 12L per minute.
When the real time information displays "2,0
m³/h", this indicates that current real time gas
consumption per hour is 2,0 m³.
