No, pool heat distributes heat to both the pool and the spa simultaneously; the spa will not be warm if pool heat isn’t turned on. Turn the manual timer on the lanai wall to turn on the spa jets and heat the spa up to 102 degrees Fahrenheit. When the jets are on, the heat will be directed toward the spa and away from the pool. Note that the spas are not “hot tubs”; they will not reach temperatures usually associated with hot tubs and cannot be heated on their own, separate from the pool.
