Product Description

140x140

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.

Specification
There are 2 installation ways for positioning the sensor of temperature and water level on the bottom part of tank:
one way is inserting sensor from hole of collector, the other is inserting sensor from bottom of tank. Diameter of installation hole is 47mm.
