So, for the first time that I could remember, we went under 35 degrees at my house. Seriously, in my part of CA, that is bigger than the invention of In and Out burgers (maybe not that big). So freeze protection kicked on like it was supposed to at 35 degrees and alternated between pool mode and spa mode every 15 minutes until the air temp was back above 35. But, I did find something odd. All three pool lights were on while the freeze protection was active and they wouldn't turn off when I hit the buttons on the remote. When the freeze protection ended, the lights went with it and everything was back to normal operation.
So, are the lights supposed to be on with freeze protection?
