First winter with open pool - what % for SWCG?

[DaveTheAccountant]

Now that my water temp is in the 50s, is there a benefit to turning my SWCG down to 10% for preserving life? Mine is undersized, so it runs at 100% otherwise.

Likely the SWCG will turn off completely due to cold water.
If not, lower it sufficiently to cover the FC losses you show via testing.

There's 2 schools of thought and nobody is wrong.

1) if it helps at all, it's a plus and it's less liquid chlorine you have to manually add at the times it kicks back on for a spell

2) it's too much hassle wondering if you'll need to step in and add LC today because the cell didn't produce yesterday. (My vote).

Unrelated : It's true that every hour the cell produces is another off it's finite lifespan, but it won't use many hours over the winter and you'll never know it failed 51 hours early (?) out of 10k hours.

Also, while wanting to preserve the cell life is a noble cause, liquid chlorine is typically more expensive, FC for FC. So it will usually cost you more to save cell lifespan. For those of us with oversized cells, it may cost 2x to 4x more.

However. You won't be needing much FC either way over the winter so I personally still prefer getting in a grove and manually dosing full time once it's too cold to produce regularly with the cell

Unlike many other SWG systems sold in the US the Jandy Truclear does not have a flow switch and a temperature sensor. The Truclear uses a gas trap to determine when it should shutdown for safety. Otherwise the cell plates have power.

You don’t see any cold water indicator on the display.

Here is what the TruClear manual says:
