The Thermostat is the only thing worth buying here. The pressure sensor leaks from the seal and the temperature sensor posts are so weak they break. Do not purchase this in a set, buy them separately. Only buy the thermostat.

I replaced these components mid October 2023. Fired up the hot tub and it worked. The next time I tried, the system tripped off on a high temperature alarm. After troubleshooting, I found the new 115 degree hi limit switch is bad. I tried the Amazon chat and got a response that this item could not be replaced or refunded. I thought there was a 90 day warranty. Be ware.

I was not happy with the product. They were sent back, broke when they were installed.

This was very poor quality. The tabs on both of the high limit switches broke right off. When held up next to the OEM pentair product the difference is huge. I wasted my money on this cheap junk. Learned my lesson. FRAUD!!!

Parts worked, but heat ended up dead after a few days. They said it probably a board. 15 years old decided to wat the bullet and buy a new one.
