Find here the temperature sensors and Hi-Limit sensors as well as their spare parts compatible with the Gecko M-Class and S-Class control boxes.
A temperature sensor, as the name implies, is used to detect the water temperature, which is indicated on the spa's keypad.
An overheating sensor (called "Hi-Limit") is a safety device programmed to activate when the water temperature exceeds 40°C, the maximum temperature generally recommended.
The latest X and Y series boxes are equipped with the in.kin technology, an all-electronic heating protection that shuts all accessories off if it senses water over heat, and the in.flo technology, an all-electronic dry-fire protection that eliminates
the burden of adjustments, calibrations and failures associated to usual water flow sensors.
