Hot Tub Thermostat
 
Sensor Limits Looking for a replacement temperature sensor for your hot tub? You’ve come to the right place! At Pool Supply Unlimited, we make it simple to find the spa replacement parts you need to keep your hot tub running its best.
 
What is a Hot Tub Thermostat Sensor Limit?
 
A hot tub sensor limit (also known as a “hi-limit”) is a safety component that is designed to protect a hot tub and its equipment from overheating. It monitors the temperature of the water in the hot tub, and if the temperature exceeds a set limit, it will cut off the power to the heater, preventing damage to the hot tub and ensuring the safety of users.
 
If you notice the temperature of your spa water is not aligned with the hot tub thermostat or your thermostat is displaying no temperature, your hot tub temperature sensor may need replacing. We offer several hot tub temperature sensors to help solve your problem. Browse our selection to find the right hot tub temperature sensor for your spa!
