This was a direct replacement in my spa and fixed an issue where the heater stopped working properly and would not heat above 95d. I was also getting a FL error on my panel which meant there was a Flow problem. Replaced with this new one and it's all good now.
Product was exactly what was described on the web site. It fits perfectly.
As always-great service & support.
Fit no problem and tub is heating once again
Been using spa depot for over 20 years always provided as described parts and great customer support with quality parts

Fixed the problem without any problem
It's a thermostate..I used it on my hot tub.
