Balboa Optional Freeze Sensor for the VS Series spa controllers. OEM part number 22312. Sensor activates at 40 degrees F.
SpaGuts P/N: 25-175-2312
This sensor gets plugged into J22 "Aux F" location near the Sensor A connection of the VS Series main circuit board. See board wiring diagram for location (J22 pin terminal location may vary for different boards). Apply thermal compound to the bottom side of the sensor (metal side), and ty-wrap the sensor with the metal side (that has the thermal compound on it) facing down onto the water line that would be the coldest in the winter time. This would be a permanent installation. Ty-wraps and thermal compounds are not included, and can be purchased at an electric supply store.

When selecting your spa or hot tub sensor, it’s critical that you go by part numbers and not just by appearances. The part number on a sensor can be found on a white or silver label located directly on the senor cable (The ID label may also be located on the casing of the sensor). Buy based on this part number. Do NOT purchase a hot tub sensor just because it looks the same as the one you’re replacing. Spa and hot tub sensors can look identical, but have different resistant and material to work with different spa and hot tub controllers or circuit boards. ALSO pay attention to the type of cable plug that is on the end of the sensor cable. Different spa and hot tub sensors use a certain type of cable plug that plugs into compatible spa and hot tub controllers or circuit boards.
