After the user touches the "Start" button, the pump starts to

work. When the water temperature reaches the set upper

limit temperature or there is no flow in the pipeline, the pump

stops working. After starting, click the "Start" button again

to turn off the pump.

The current time is within the set period. If the water temperature is lower than the set lower

temperature limit, the circulation pump starts to work. When the water temperature reaches the

set upper temperature limit or there is no flow in the pipeline, the water pump stops working.
