1.3 function keys,6indicator lights,1 led digital tube display function keys
2.A.on/off key(middle) b.power level ▼ key(left) C.power level ▲ key(right)
3.Indicator lights:6 red quadrate Led
4.Display:two digits red8 led digital tube
5.The functions:
a)After power connected,digital tube flashes--,no other signals
b)When you press on/off key ,digital tube lights and displays instant temperature(water temperature of outflow opening),which means the unit gets ready for operation;press on/off key again,digital tube flashes to display--;
When the unit get ready,press power level ▼▲keys;there are six power levels,which are indicated by ths six LED indicator lights(corresponding power rating 1.5KW-8KM);
When you finish adjusting power level,ths six indicator lights will twinkle in turn,which means water heater is in heating.
The functions:
A. Only after water switch(magnetic induction signal)is closed over 3 seconds,it can start heating;once the switch is disconnected,heating is stopped immediately;
B. When the leakage(10-15mA)detectingnsignal is effect,the system will stop heating immediately,with all indicator lights off,as well as digital tube displays malfunction alarming signal E2(leakage),now the system is in automatic detecting,and it will turns to operation state after the malfunction is solved;you can re-start with the keys
C. The precision of temperature detecting is ±2℃,when sensor detecting finds exceptional malfunctions such as short circuit,open circuit,over heating(water temperature≥65℃) etc,the system will stop heating immediately,with all indicator lights off,as well as digital tube displays malfunction alarming signal E1,now the system is in automatic detecing,and it will turns to operation state after the malfunction is solved;you can re-start with the keys. |
