temperature < return water set temperature, and the current water tank temperature ≥
return water set temperature + return water temperature difference, the return water

If backwater pipe temperature ≥ return water set tempe return water temperature
difference for 5 seconds or temperature control return water time ≥ 2 minutes, the water
pump will turn off.
The buzzer sounds three times, prompting the user to use hot water; When the pipe
temperature < return water set temperature, the water return pump is started again and
