Factory Setting Function
When in the power off state, if the “MODE” button and the “POWER”
button are pressed for 3s simultaneously, the display screen will be
fully bright and the system will enter into the factory setting mode
(buzzer will ring, if any). Then, the system will enter to the
“heating/heat preservation” state after 2s. The factory setting
parameters are shown in the following table.
The Basic Parameters of Factory Setting
Function Factory Setting Parameter
User setting temperature 70 ℃
Booked time 8 hours
Booking mode Default cancel
Power 600W (Heating at full speed)
 Alarming Function and Self Problem Detection (Not Available in
Empty-shell Machine)
If there is a problem due to several cases (such as dry-heating,
over-temperature and sensor turn off the heating device or short
circuit), nixie tubes on the display screen successively show E2, E3
and E4 with blinking display. All other nixie tubes and the indicator
lights will not show signs. For instance, if there is a buzzer, it will
give six short alarms. At this moment, all relays are switched off
and all buttons do not work. After the problems are solved and
electricity is connected again, the water heater will recover to the
power-off state. In the
power-on
state, the system will
automatically conduct machine inspection. If there is a problem, the
corresponding error code will be displayed accordingly, and the
system cannot be operated (i.e. the water heater is unable to
start.)

Identification of the Dry-heating Problem
If the system detects the rising of inner container temperature that
is in ≥ 15
o
C /min or ≥ 8
o
C /30s, and the temperature is greater than
50
o
C, the error code E2 will be shown on display screen with
blinking display.
