Last night, OAT in the area must have reached close to 37ºF as the "freeze protection" feature in my system was turned on. PB had set it up to run the filter pump, water features pump and cleaner pump. My two questions are: does the cleaner pump need to be freeze protected (my understanding is that the filter pump moves water through the cleaner pipes as well) and 2) can I change the temp. at which freeze protection kicks in? I have the Easy Touch Pool & Spa Control System, but don't see an option to change the temp.
