SR201 is controller with micro-computer-full-automatic used for integrated non pressure solar water heater. It is developed with high-performance 32-bit single-chip microcomputer to realize intelligent control. All devices adopt industrial standard, and can operate freely in cold, high temperature and humid environment.
At the same time, clock chip make sure time control accurate. The controller has the advantages of LCD display, with beautiful appearance, more stable and reliable performance, and convenient installation. It has become the most ideal supporting product of solar water heater.
SR201 offer by with Chinese version and English version
