Why is my water temperature creeping above the set temperature?

Due to your Beachcomber hot tub being extremely energy efficient, your filtration time is set to run too long or during the daytime hotter hours, causing the pump to heat the water above set point. See your owners guide on how to change to fewer hours and also set to run at cooler night time hours. F2 (filter two hours) 1n (night time) should correct this issue
