4. SOLAR CONTROL SYSTEM User Manual Solar control system is composed by design a touch screen design controller and a main board By sensing the temperatures in different position and communicating with each other the controller and main board can operate the pump station for heat exchange between solar collector and water tank domestic water circulation and the auxiliary heating device The intelligent control system makes it easier and more convenient to run the solar system automatically With microcomputer the large LCD display helps you track the temperature in four positions control the circulation via pump station and operate auxiliary heating FUNCTIONS Monitor and display the temperature at solar panel T1 m Periods programmable for auxiliary heating ith Green backlight Over heating protection for water tank ih Monitor and display the temperature at bottom of m water tank T2 Monitor and display the temperature at top of water tank T3 Monitor display the temperature of domestic water m Intelligent control of water tank heating y m One step reset to default setting Combined with boiler by control 3 way motorized valve m y m Automatically snow melting y Temperature calibrating Clock m Problem diagnosing y SPECIFICATION Temperature measuring range 5 95 C Self Power
