SR501 Controller for Low Pressure Solar Water Heater Temperature
Sensor Control
Introduce:
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.
