4.2.3 Detailed description of functions
4.2.3.1 Heating/Heat preservation function
The system could judge heating/heat preservation state and light up the corresponding indicator
based on the difference between actual temperature and setting temperature. If the water heater is in
heating state, indicator “HEATING” lights up (bright green); indicator “READY” lights up (bright red)
when in heat preservation state.
The water heater could be directly heated to the setting temperature after just starting or readjusting
the setting temperature. When the setting temperature is reached, it will stop heating and enter into
the heat preservation state. If the difference between actual temperature and setting temperature is
greater than the temperature return difference, water will be heated again.
