from 10:00 to 10:00 am, it means there is no back-up heating in this
time.

If you want to shut off one timing heating, then you can set the turning on time and turning
off time with a same value ( for example, no this function during the second time section,
then you can set turning on/off time is 10:00 ~ 10:00)
When time is outside of the preset schedule, back-
up heating doesn’t work automatically
even when the tank temperature reaches the switch
–on temperature of heating.
Note:
When there is no sensor installed in the top part of tank (no T3 sensor), controller will
take the signal of T2 (sensor in bottom of tank) automatically to control this function.
The time in this controlled is 24 hours mode, when you set schedule, the switch-off
time of heating should be larger than the switch-on time. For example: if you set the
switch-on time of heating is at 17:00, but switch-off time of heating is 6:00, then this
setting doesn’t take effect, that means within this time section, heating function doesn’t
work. The correct set is like flowing: it should be divided into two time sections, one
time section is from 17:00 to 23:59, the other time section is from 00:00 to 06:00.
