Can your pool heat pump control the water circulation pump economically?

Yes. We have 3 modes for water pump. The 3rd one is ecomomical as below:
When the water reaches target temperature, the heat pump shuts off, and the water pump shuts off. But after 15 minutes,the water pump will turn on for 15 minutes to probe the pool water temperature, then turns off for another 15 minutes and then turns on for 15 minutes. This process will continue until the water temperature lowers and heat pump turns on again, then water pump will run.
