Abstract:
1. A device for regulated water heating using energy derived from photovoltaic cells, the device comprising terminals (X 1 , X 2 , X 3 , X 4 , X 5 ), where to the terminal (X 1 ) an electrical ground (PE) is connected, which is then connected to a thermostat (T 2 ), whereas to the terminal (X 2 ) a line conductor (L) of the alternating current is connected, which is then connected to a normally closed contact (Y 1 ) of a thermal fuse (TP) and then the line conductor (L) is connected to a normally closed contact of a thermostat (T 2 ) and then the line conductor (L) is connected to a terminal (A 1 ) of a coil of the contactor (ST), whereas to the terminal (X 3 ) a neutral conductor (N) is connected, which is then connected to a normally closed contact (Y 2 ) of the thermal fuse (TP) and than the neutral conductor (N) is connected to a terminal (A 2 ) of the coil of the contactor (ST), whereas to the terminal (X 5 ) a conductor (L+) of the direct current is connected, which is than connected to a terminal ( 1 ) of a switch of the contactor (ST) and than the conductor (L+) brought from a terminal ( 6 ) of a switch of the contactor (ST) is connected to an inlet terminal of a heating coil (R 2 ), whereas to the terminal (X 5 ) a conductor (L−) of the direct current is connected, which is then connected to a second inlet terminal of the heating coil (R 2 ).
