I have jandy controls that are connected to 3 pentair vs pumps, they have freeze protection circuit.
Also have swim jet pump, and cleaner pump.
Vs pumps are for filter, spa boost and water fall.
When it gets cold only the main filter pentair pump is set to come on. And it seems to ignore the programmed freeze protection setting. And it runs at whatever rpm it's programmed for for main filter use.
Is there some hydraulic connection that keeps water moving in the other 2 pentairs when only one is on ?
there is no freeze circuit for the other 2 pumps. I was told by one guy that he water drains out of those so don't worry about them.
What would you do in winter in dallas ?
Set all 3 pentairs to turn on at a low rpm ?
Cover the other 2 pumps ?
Use a drop light and a canvas drop cloth cover and call it done ?
Thanks in advance
