Solar Water Heater Controller SEA-SC-1910(for pressurized solar water heater) 

SEA Solar hot water intelligent controller is the product that applies the single chip microcomputer (SMC) 
technology and it has been made through many living imitation experiments to optimize the controlling 
software.  The controller brings functions that ensure the solar system works efficiently, to achieve 
automatic controlling of water level, displaying of water temperature and automatic loading of water etc.
