Modes
There are two types of modes depending on the actual water temperature inside the inner
tank of the water heater:
Heating mode
When the actual temperature of the water
is less than the set temperature, it enters
into Heating mode. The Heating LED
indicator glows as shown in (Fig. 25).
Figure 25
When the temperature of the water drops by 5°C from the set temperature due to usage of
water, the water heater again enters into the Heating mode.
Standby mode
After the water heater reaches set temperature,
it will enter into the Standby mode due to
thermostat cut-off and Heating LED indicator
switch off as shown in (Fig. 26).
