Water circulation controller for central hot water supply of building, has custom-memory, where memory value of current valid day time-interval in custom-memory determines output variable of low-pass function

摘要

The controller has a custom-memory, where a memory value of a current valid day time-interval in the custom-memory determines an output variable of a low-pass function. An input variable of the low-pass function is determined from a cyclic sampling checking result in a mentioned interval. A taping operation is processed during a proximate day-period for specification of a content of the memory. A sensor for detecting the taping operation acts as temperature sensor if a mounting tube is heated.
