Radio frequency card intelligent HVAC valve, also known as radio frequency card intelligent heating timing controller. It is mainly composed of intelligent time control valve, prepaid charging system and radio frequency card, is a mechanical and electrical integration products with heating intelligent management and control functions. Tianjin Yitongda production of radio frequency card HVAC valve using mature high-tech hardware integration, after technological innovation and invention of intelligent energy-saving products, through continuous improvement, in the premise of high operational stability, with a number of core technologies and features: 1, using the U.S. Texas Instruments (TI) of the MSP430 series of single-chip microcomputers, ultra-low-power hardware and software design, embedded information memory, power failure data is not lost. 2, the use of radio frequency MSP430 series of single-chip computer, ultra-low power design, embedded information memory, power outage data is not lost. 2, the use of radio frequency non-contact IC card technology, combined with multiple security measures, with a high degree of security and confidentiality performance. 3, the use of special static zero-power electric ball valves, with a high output torque, low power consumption, anti-scaling, corrosion-resistant, small pressure loss, etc., and has a regular wash valve function. 4, unique energy-saving features designed to open the valve when in use, not in use when the valve is shut off, so that the user's energy-saving and cost savings associated to improve the user's energy-saving positive Correlation, improve the user's energy-saving enthusiasm. Energy-saving switching valve operation increases the battery purchase cost is far lower than the energy-saving gains, so that energy-saving design is practicable.
