热量表类型:直读式 性能及特点Properties and characteristics
●智能化管理、实现了预付收费管理；
●回写功能：用户刷卡的同时会把暖通阀状态写刷卡中，便于管理中心了解暖通阀的运行情况；
●欠电保护功能：当检测到电池电压低于设定值时，提示性自动阀，运行的数据自动保存；
●定期自检功能：定时开关阀防止阀门长时间不用而“锈死”；
●“普通模式”和“节能模式”，由管理部门自行选择。
●Intelligent management,realized the advance fees management
●Towrite functions:the user will also take the credit card of hvac valve state ,to write about management center of valve operation ,Heating
●Owe protection function:when the battery voltage detected than setting ,indicative of automatic valve,operation data automatically preserve.
●Regular self-checking function:timer switch valve to prevent valve for a long time withour “rust”
●“Commonmode”and “model”,the management department to choose.
