Lately the water features turned on with freeze protection mode are not turning off after the air temp warms up and freeze protection mode is no longer active. In the app, the waterfall switch shows active and will turn off when asked, so it seems to be a Zodiac Automation issue. I don’t want to overlook the possibility that this could be an early warning sign of a hardware failure that could fail to turn on when it should resulting in freeze damage. Any thoughts?
