Electric heater resistance

In order to protect the electric heater, we are fitting two sets of the resistances, they are 80C % 110C.

Working: when the electric heater are working, if the temperature up to 80C, then this resistance can stop the working itself automaticlly.

Whenever the 80C resistance doesn't work normally, then the temperature will come up quickly, if the temperature is near 90-100C, then it is a little dangerous, then 110C reisistance will work automaticlly, stop the electric heater.

Sometime there are no water inside the tank, we call it " empty heating", it is also very dangerous, the two resistance can protect the heater.

Attention: if the 80C resistance works, when the temperature come down, lower than 80C, then the electric heater can work again. but if the 110C resistance works, then the heater can't work again ( need hand maintenance), that means there is something wrong with the system or the electric heater, please call the technical person to check.

Don't open the heater by yourself.
