SPA HEATING
There is a Spa remote located in the pool area outside, just around the corner from the covered porch, mounted on a post. See pic below.
Just tap the Spa button to turn on heat. The Spa will heat to 103 degrees and will stay on for 3 hours before automatically turning off.
****THE HOT TUB AND POOL CANNOT BE HEATED AT THE SAME TIME. If you start heating the spa while the pool is heated, the pool temp will decrease.
