SR501 Solar Intelligent Controller for Compact Solar Water Heater Solar Smart Controllers

 

Introduction:

SR501, micro-computer automatic controller for solar water heater, It is used to control integrated un-pressurized solar thermal system. It is developed using the latest NEC high-performance microcontroller to achieve intelligent control; All devices are industry standard and maintain good operation in cold, hot and humid environments.
At the same time, it uses a dedicated clock chip, accurate time control. The controller uses LCD liquid crystal display, the appearance of beautiful, stable and reliable performance, easy installation, making it the best matching products for solar water heater.
