Control system Work principle 

The temperature sensor and water level sensor put into the water tank, and the electromagnetism valve fix in the water pipe line. The sensor and electromagnetism connect to the digital adjustor. So it can display the temperature and water level valve, of cause you preset the temperature value and water level, once their value is below the preset value, the digital will start the electromagnetism in the pipe line then supply water for water tank, at the same time it will start electrical heater or gas heater booster. Some times, the electrical heater or gas heater is not necessary to connect to digital adjust directly, if they have their own thermostats. 

So if you use the microcomputer control system, you do not need an assistant tank to control the water level. The voltage of the controller can be choosing rang from 100V-230V; The common voltage is 110V and 220V in most country.
