Temperature sensor set for older Balboa spa controllers. Generally suits Balboa controllers with a pressure switch on the heater tube. One sensor fits into a pocket in the spa wall, and the other slips into the heater element sleeve. Having a spare set of sensors is mandatory for any Spa technician. May resolve some sensor errors.
