Iaqualink freeze protect - spa mode?

[atxjmy512]

Within the freeze protection settings for iaqualink - should spa be checked too to make sure water flows through those pipes?

If so - how does that work? Does it switch between filter pump and spa mode periodically or send water through everything simultaneously?

If you select Spa it will alternate to Spa Mode, moving the valves, but not firing the heater, every 15 minutes.

Thanks! Safe to assume I should enable this?

Or just adjust the actuators using the toggle switch to get some water through the suction and return line’s while in Pool mode.

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...

This would reduce flow overall correct? I know that won’t matter in term of freeze protection, just trying to get a sense of the merits one method vs the other. Lower but constant flow vs stronger but intermittent flow that cycles every 15 minutes is essentially what I’m picking between?

Correct. Not moving the valves every 15 minutes is the plus. Less wear.

Quick question. Do I open both the spa return and spa main drains in the “less wear” method? I can’t figure out how to get my spa main drain actuator should be fully open and not block the main pool drain.

Mine will only articulate 90 degrees - either open spa drain & closed main pool drain or closed spa & open main. I can camber it open maybe half way between the two but the electronic actuator will only move that 90°.

Use the toggle switch. Let the valve move enough to allow some flow then put the toggle in the Off position.

I am. It stops after 90° of movement which is really strange because I have the same exact model of actuator on my return lines and it articulates a full 180° when using toggle.

There are three positions of the toggle switch. On1, Off, On2.
Once the valve is cracked open to flow for spa, move the toggle to Off.

Got it. So stop it roughly when it's point 45 degrees. I don't need it fully open for flow, cracked is enough?

I would say more like 10-15 degrees, but enough for flow.
