Reliable Temperature Monitoring
Each Zodiac Jandy Hi-Limit Switch utilizes a sensitive thermal sensor to constantly monitor the water temperature. If the temperature reaches 130°F, the switch will immediately interrupt power to the heater, ensuring your system remains within a safe operating range.
Automatic Safety Cutoff
These Hi-Limit Switches provide an added layer of protection by automatically cutting power to the heater in the event of a temperature spike. This eliminates the need for manual intervention, enhancing the overall safety of your Zodiac Jandy heater.
Easy Replacement
Designed as a direct replacement for Zodiac Jandy LRZE, LRZM, and Lxi heaters, the Hi-Limit Switches can be easily integrated into your existing system. This allows you to upgrade or repair the safety components with minimal disruption to your heater’s operation.
