How can I cool down my hot tub during summer months?

The lowest you can set your tub is 80^oF/26^oC. To cool down your tub, you can change the heating mode to SL = Sleep Mode. In this mode the heater will stay off until water temperature falls to 20^oF/10^oC below your set temperature. However, your hot tub does not have a cooler in it - so if the outside temperature is hotter than 80^oF/26^oC the water in your hot tub will be a similar temperature. Keeping the cover off will allow heat to disperse. Note: SL mode is typically only used for vacation time.
