Heating system operating method, involves comparing condition change of mixer with preset threshold value for condition exchange of mixer, and reducing reference mixer operating time as parameter in control device when value is exceeded

摘要

The method involves providing a heating circuit with a pump and a mixer consuming heat. An actual operating time of the mixer is provided between on-condition and off-condition. A reference mixer operating time is adjustable as a parameter in a control device. A condition change of the mixer is counted between the on and off conditions in a preset time space and compared with a preset threshold value for the condition exchange of the mixer. The reference mixer operating time as the parameter in the control device is reduced when the threshold value is exceeded.
