1． Digital display temperature , the range is from 0-70 ℃.
2． Temperature allows to setting from 20-60℃, default is 35℃.
3． 55℃ over heat protection
4． flow switch + water level probe double protection to prevent from the heat elements working in air
5． Flow switch time-lapse 20 seconds.
6． Water level probe time-lapse 5 seconds.
7． Diagnostics system,6 indicator LED shows power supply, heating ,temperature keeping, flow rate ,water level, over heat different work stages and operations that can be used for elementary diagnosis if a problem should occur.
