Description:
In order to avoid occurring bacteria in water tank when the temperature of tank is lower for
a long time, controller will check the temperature of tank every 7 days in a period
automatically, if the temperature of tank is never over 70
o
C during this period, then at the
factory default time of 01:00 on seventh day, auxiliary heating system is triggered
automatically to heat water until its temperature rises up to 70
o
C, bacteria is killed by high
