1.Intelligent management, realize the prepaid charge management.

2.Data memory: the card can remember the warm valve data and can transfer it to the administrator, enable easy management.

3.Low power supply protection: the valve will be closed automatically when find the low power supply meanwhile data saved.

4.Self-inspection: regular test to protect valve from rust.

5.“Normal mode” and “energy conservation mode”, decided by administration section.

6.Unique online charging system, easy to realize station and sub station communication, make card and read data.

7.Low temperature protection function ,to prevent the pipe be cracked when valve closed in a lower ambient temperature

8.RF card, without any electrode exposed, well damp-proof and easy to use.

9.User card with double key encryption, one card one password.

10.Remind user to charge the card when remaining time is not enough. Remind user to change battery when low power

11.Data reading function: when user goes to administration center to charge the card, the accumulated warm consumption volume and battery status can be read by administration center.

12.Display function:purchase volume, remaining volume and accumulated consumed volume can be displayed on the LCD screen, and user can check the remaining and consumed volume of the meter via the card.

13.The M-BUS remote control card-swiping valve is applicable to “188 protocol standard”, and auxiliary products of heat metering reform.


It is used to measure and control the heating situation of the users, so that the users are freely 
distributed and controlled by the users (energy saving application), and the unnecessary waste is reduced

Operation instructions:

This valve timing and purchases are in hours, purchases of card case, energy-saving valve users every brush user card   

will move a valve (" on "or" off "), ordinary users only valve after purchase and warm card for the first time the valve

opens, then charge when the valve is not action, but shows the basic information.

1. Display and reading instructions.

Figure 1  exchanging data  

figure 2 buy one hour this time



4, the method of reading: user want to see her with warm situation at ordinary times, put the user card in the valve

of radio frequency induction zone awaken the LCD panel, then the valve will shut down automatically (energy saving),

then in turn on the LCD panel shows you the latest cumulative amount of residual amount, a new, as shown in the figure

below, the parameters such as the valve closed at this time, please brush user card again, the valve will automatically

open (energy saving).




(valve in action)


(The cumulative amount is 107 hours and 20-29 points.)




(Show this new purchase for 30 hours.)

(Show the remaining amount is 55 hours, 50-59
