Tome control valve is a device of the heating supply system that fulfills automatic charge collection and management. This valve adopts IC Card to conduct prepayment management, and under Holley Management System, integrated with heat meter, it could easily fulfill the function of heating charge collection and control.
Could be set with multistage alarming times upon user's request, when reaching the alarming time, LCD screen will display "recharge" and the buzzer will ring three times within every minute, which could be dispelled by inserting user's card.
After the insertion of user's card, the loop display contents at least contain the following information, deadline date (automatically close the valve when time reaches), blocking time, accumulated working days, current date, current time, stage I alarming days, stage II alarming days, class number, valve's condition etc
Battery Reactivating Function:
By the end of each month, valve will automatically open and close one time, by this means to discharge and activate battery.
Under voltage Detection:
When the battery is under voltage, low voltage mark will show on the LCD screen and the valve will close, after card insertion, a maximum 3 days after valve open will be available; Professionals are needed for battery replacement.
