Description
technical field [0001] The invention relates to the field of circuit control, in particular to a circuit control module in a boiler controller. Background technique [0002] Boiler is a multi-input, multi-output, multi-feedback system that requires multiple temperature adjustments, display adjustments, and many interference factors. Therefore, the performance of the boiler controller is directly related to the safe and reliable operation of the boiler. At present, there are many potential safety hazards in the boiler. There have been many phenomena such as boiler dry burning, pipe burst, fire extinguishing, container flooding, temperature failure, no alarm, explosion, etc., causing huge safety hazards to the people and great losses to enterprises. property loss. Because the use environment of the boiler controller is relatively extreme, after a short period of use, the function will weaken or fail, and there will be problems such as large temperature error, garbled display,...
