Solar controller SR91

SR91 designed to regulate and control operation of the circulation pump, guided by data obtained from temperature sensors. They are mounted on the tube issuing from the solar collector and the inlet and outlet to the storage tank. Safe and effective performance of the system as a whole largely depends on the water treatment operation of the controller, so proper selection of its very important
