Welcome to our forum.
The Hot Spring panel shows the "Set" temp, not the actual temp. You will see a green light come on when the spa is at the "set" temp. I believe you can change a couple of jumpers in the control box to display actual temp. Most folks just set their desired temperature and leave it, knowing their spa will be at the correct temp.Enjoy your new spa.
you would think for the money you pay for a HS.... they would give you a digital read out of current temp.
I think when it is set to 100 it can heat to 102 then shut off and the heat will come on at 98.
Well, that would be a large unexceptable window of temperture change if you ask me!
