Control system capable of selecting heat source

The utility model relates to a control system capable of selecting a heat source. The control system capable of selecting the heat source can select different heat sources in different stages, and is characterized in that hot water of different temperatures can be supplied in different production operation stages. The control system capable of selecting the heat source comprises a baking room, a heat source controller and at least two water tanks. A heat exchanger is arranged inside the baking room. The heat exchanger is communicated with each water tank through a water pipeline. At least two water tanks are arranged in parallel. A water tank temperature sensor is arranged inside each water tank. A baking room temperature sensor is arranged inside the baking room. A valve is arranged on a corresponding pipeline on each water tank. The heat source controller is respectively electrically connected with the water tank temperature sensor, the baking room temperature sensor and the valves. Through the novel contro
