The flat-plate solar all-in-one machine further comprises a self-resetting temperature controller 7 and a current limiting switch 8. The signal output end of the self-reset temperature controller 7 is connected with the control end of the direct current heating pipe 5, the self-reset temperature controller 7 is powered by the battery component of the PVT heat collector 2, namely the self-reset temperature controller 7 is connected with the battery component of the PVT heat collector 2 through the electric wire 6. The self-reset temperature controller 7 is used for controlling the switch of the direct-current heating pipe 5, the power is supplied by the battery component of the PVT heat collector 2, and the photovoltaic energy of the PVT heat collector 2 is fully utilized.
The current limiting switch 8 is connected in series with the power supply end of the self-reset temperature controller 7. The self-resetting temperature controller 7 is effectively protected by the current limiting switch 8.
The signal input end of the self-resetting temperature controller 7 is in circuit connection with a temperature sensing probe 9, and the temperature sensing probe 9 is arranged in a blind pipe 10 of the water tank liner.

In order to prevent the temperature sensing probe 9 from being affected by the heat generated by the dc current, an isolation should be provided between the temperature sensing probe 9 and the self-resetting temperature controller 7.
In the present embodiment, if the self-resetting temperature controller 7 and the temperature sensing probe 9 are rigidly connected, both the self-resetting temperature controller 7 and the temperature sensing probe 9 may be provided in the blind pipe 10, and a heat insulating material may be provided between the temperature sensing probe 9 and the self-resetting temperature controller 7.

When the temperature detected by the temperature sensing probe 9 is lower than T1, the direct current heating pipe 5 is normally heated, the water in the water tank 1 is heated by combining the light heat energy source provided by the PVT heat collector 2, and when the temperature reaches T1, the direct current heating pipe 5 is disconnected. When the direct current heating pipe 5 and the light heat energy source are insufficient in heat supply, and the real-time temperature T acquired by the single temperature sensor of the computer board is less than T2, the alternating current heating pipe 4 is started to assist in heating, and when the temperature reaches T2, the alternating current heating pipe 4 is disconnected.
