Hello Everyone, I am new to this forum, if anyone can help me out it would be greatly appreciated. I have a spa manufacturer style spa, made in clearwater florida, my tridelta 4 button topside controller reads 40 degrees, when I raise the digital temp. to desired temp and let go of the button, it automatically goes back to 40 degrees. While i increase the temp, the heater kicks on, but then kicks off when the temp display plummets back to 40 degrees. I can manually turn the heater on on the spa pack below, but I have to manually shut it off, not knowing what the actual temp is. I have also tried to reset, but no luck yet. Not sure if it is a temp sensor or thermostat, please any guidance would be appreciated.
Chris
