Control system

Working 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, of course you preset temperature value and water level value, once their value is below the preset value, the digital will start the electromagnetism vale 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 adjustor directly, if they have their own thermostats.

So if you use the microcomputer control system, you needn’t an assistant tank to control the water level. The voltage of the controller can be choosing range form 100V-230V; the common voltage is 110V and 220 V in most countries.
