Description
technical field [0001] The invention relates to a control device, in particular to an energy-saving heat exchanger water pump delay automatic shutdown control device. Background technique [0002] At present, the heat exchanger generates a lot of heat when it is working, and there is still a lot of heat for a long time after it is just closed. Now every time after the heat exchanger is turned off during operation, it is necessary to manually turn off the corresponding water pump of the heat exchanger. There is a lot of instability in this kind of control, resulting in insufficient utilization of energy and increasing labor costs. Therefore, this control method is not very ideal in actual work. [0003] Chinese patent CN 102393065A discloses an electric water heater that saves electricity and water, and belongs to the technical field of water heaters. It includes the main engine, the water inlet of the main engine and the water outlet of the main engine; the main body of th...
