We have a system inside the house to be able to control the pool and spa and for some reason everything works except the heat control for the spa. I need help
The way you are asking this is like saying "The heat doesn't work in my car. Can you help?"
Can you see how vague this is?
My strong professional suggestion is to call in a technician familiar with your system.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
