<p>The device for regulated water heating using the energy gained by photovoltaic cells, which consists of terminals (X1, X2, X3, X4, X5), where to the terminal (X1) is brought a protective earth (PE), which is then brought to a thermostat (T2), whereas to the terminal (X2) is brought a line conductor (L) of the alternating current, which is then brought to a normally closed contact (Y1) of a thermal fuse (TP) and then the line conductor (L) is brought to a normally closed contact of a thermostat (T2) and then the line conductor (L) is brought to a terminal (A1) of a coil of the contactor (ST), whereas to the terminal (X3) is brought a neutral conductor (N), which is then brought to a normally closed contact (Y2) of the thermal fuse (TP) and than the neutral conductor (N) is connected to a terminal (A2) of the coil of the contactor (ST), whereas to the terminal (X5) is brought a conductor (L+) of the direct current, which is than brought to a terminal (1) of a switch of the contactor (ST) and than the conductor (L+) is brought from a terminal (6) of a switch of the contactor (ST) to an inlet terminal of a heating coil (R2), whereas to the terminal (X5) is brought a conductor (L-) of the direct current, which is then brought to a second inlet terminal of the heating coil (R2).</p> |
