Is it possible...

With a Hayward Swim Pure, is it possible to have both top two lights (Power & Generating) to be GREEN and the water be too cold (53) for it to be producing chlorine?

I have had it running 24/7 for 3 days and losing 1ppm per day. No other lights are lit.

What are the diagnostic readings?

NOTE: Output is scaled back to 20% or lower (depending on where the dial is set) at 60°F and chlorine production stops altogether at 50°F.

Between 50 and 60 degrees, the output is 20% of the actual setting.

I just turn mine off at this time of year and add liquid as needed. This last week I've only lost .5ppm of FC and that is also with the spa running a couple of days. My water temp is in the mid 50's right now and I'm thinking your pool is using a lot of chlorine for your water temp if you are measuring 1ppm of loss each day.
