Inlet valve will open automatically once the system has started and will fill with water until the water level
reaches maximum level. If water level is still lower than the minimum water level 10 minutes after, it indicates faults of the water supply system, so all heating elements will stop working and LCD will display “-E”.
Auto heating up by sections:
Generator will compare the measured room temperature with the setting temperature and then decides the number of working heating elements.
Auto water supplementing:
If the water level is lower than the desired level when operating, auto water supplementing function will be on and open the inlet valve. Once the water level reaches the desired level, auto water supplementing function turns off. If water level is lower than the desired level 3 minute after the water supplementing order is given, it indicates faults of the water supply system, so all heating elements stop working and LCD displays “-E”.
When setting time is over or ON/OFF button is pressed, system will drain automatically and displays ‘-d” on the LCD. The drainage valve and the drainage pump will be turned on to drain. After a while the system will open the inlet valve to fill in water in order to wash and cool down the inner tank and heating elements.
The whole process takes about 3 minutes, and the system will be shut off automatically after drainage.
