SR201 1.5KW Solar Controllers for Compact Non Pressurized Solar Water Heater

SR201 microcomputer automatic controller is used for intelligent control of Integrated non-pressure solar water heater. It is developed with the latest NEC high-performance single-chip microcomputer and realizes intelligent control. All devices adopt industrial grade standard and can operate freely in cold, high temperature and humid environment. At the same time, the clock chip is used to make the time control accurate. The controller LCD liquid crystal display, beautiful appearance, stable and reliable performance, easy installation, is the most ideal accessory product for Integrated non-pressure solar water heaters.

The SR201 solar controller can display the water temperature and water level; control the water tank water supply through water temperature, water level and time setting; and can control the electric heating and other ancillary equipment to fully control the solar water heater. The list of more features is as follows:

1.Time setting
