Jandy Freeze Protect Cycle Spa/Pool

It looks like that the Houston area will get a rare arctic blast in a couple of days (highs in the 20s, lows in the teens).

I have a Jandy RS-8, and currently have the Filter, Cleaner, and Waterfall pumps scheduled to turn on when the freeze protection cycle kicks on.

In our last pool, we had Pentair equipment, and I remember the freeze protection logic cycling between pool and spa mode every 30 minutes. Is there the same logic on the Jandy system?

In the meantime, I have added Spa to the list of items that will activate in the freeze protection cycle. Will that cycle between pool and spa mode for a certain interval?

Thanks in advance!

If you have checked the box for both pool and spa to go on at freeze protection then they will activate. I am not sure of the time cycle between the 2 as I have never done that. In pool mode, I have flow to my spa for spillover - it is always on so I do not set the spa for freeze protection.
Not sure what type of cleaner you have but if it is pressure side cleaner like a Polaris then in Pool mode the water naturally flows through it. The purpose of the booster pump is to create the higher pressure needed to push the cleaner.
Also, it would be good to cover your equipment pad with a tarp. Tie it down so it does not blow and ensure nothing can touch the pump motor. Also, do not turn on your heater. With the pump running under the tarp, it should generate sufficient heat to keep the surface pipes above freezing. Just ensure there is some ventilation under the tarp for pump to not overheat.

If filter mode is active and then you also activate spa mode my RS system goes into spa mode. If both the filter mode and spa mode are checked for freeze protection I would image spa mode would also take priority.

You may want set the freeze activation temp to something above your current outdoor temp so that the freeze protection activates so that you can see how it behaves regarding the filter and spa modes?

Thanks for the replies so far.

HermanTX, I have a Paramount IG cleaner (which has its own pump), so I figure I’d keep that water flowing during freeze protect as well. Good call on the tarp. I put one over the equipment and pipes, held on with bungee cords.

So I’ve raised the freeze protect temperature to test, and it doesn’t go into Spa mode (at least the couple of times I’ve checked).

Really, the only thing I’m worried about is the valve that toggles between spa and pool mode. But, since I now have the tarp over everything, it may render that a moot point.

The poor pool equipment is going to be running nonstop for almost a week!

*** UPDATE: Just checked, and it just cycled to Spa mode. I don't know when it did it, but if I had to guess, it was at the 30 minute mark. ***

Keep an eye on that actuator valve switching cycles in this weather. Three days ago when Tulsa began the ice/sleet event leading into this frigid week, my valves stopped cycling completely in freeze protection mode. We didn’t realize it until the spa drained way down and the top jets began spraying what was left all over the yard. After inspecting the suspect actuator valve, it had started to form ice in the time it took for the cycles to change in freeze protection mode. I have a spillover from my spa, so after refilling the lost water, I manually set the actuators to 80/20 so water would constantly move through the pool loop and spa loop without that freeze protection cycle delay. Once the valve was where I wanted it, I switched the actuator to “OFF” so it would stay put. So far, so good.
