Balboa sensor kit assembly - Temp/Hi-Limit

This kit contains two Balboa sensors that use the same socket: one for temperature and one for overheating protection (called "Hi-Limit").

The temperature sensor should be installed in a waterproof gland mounted in the shell of the hot tub, so that it is in direct contact with the water. The hi-limit sensor installs in a metal pocket on the outside of the heater.

It is compatible with almost all Balboa control systems that use a pressure switch.
